Windows XP black blinking monitor/NV4_disp error

Q: Windows XP black blinking monitor/NV4_disp error

I think this is a video card error but am not sure. I did restart my computer in safe mode and it works fine this way. I did update my driver but it didn't help any. I am getting a full black screen that sits there for 3-7 seconds then you see the internet explorer page then when I try to search or go anywhere theres the black screen again. I only put the computer in safe mode to see if it was the monitor or not. Ive never had this happen before. Please help!

I need some help. I have acomputer monitor that is roughly 10 years old. THe monitor last night decided to suddenly turn off and the power button started blinking. I unplugged the power to the monitor and let it sit overnight. This morning I went and plugged the power back into the monitor and pressed the power button on it. When I pressed the power button the button started blinking again. I have never had a monitor die like this and I would like to know why it died and if it can be fixed. Some more info is that i had only been on the computer for less than 2 hours. I have not spilled anything on the computer, the vent is completely uncovered, and the computer is in good working conditions according to the mannual. I need to know asap please. The tower still works perfectly fine it is only the monitor.

A:Monitor is black and the power button on the monitor is blinking

If you could try the monitor on another PC, that would confirm the monitor is faulty. In any case if the monitor is bad and considering its age, it would be best to just replace it. It would not be worth fixing.

Hi, I've got a problem with my laptop not booting Windows 10.

Asus N71vg
Dual boot OS Windows 10 (main partition + 1 data)+ Ubuntu 14.04

Ubuntu boots ok, but I wasn't able to mount and access two partitions that were used by Windows.

Windows won't boot. After selection in grub menu boot sequence doesn't proceed further than black screen with blinking cursor.

I tried using Windows recovery usb:
System restore, Image recovery are unfortunately not an option.
Startup repair couldn't repair it
Via Command prompt I was able to access files on both of my drives.
There isn't an option to enable Safe mode (I don't know why).

Since Ubuntu is working OK, my guess is that something is corrupted with partitions or MBR. Reinstalling Windows is an option, but I would rather not have to.

I was following this thread, but I am not sure what to do or to read out whether my disk is ok and that is a problem for win7.

Another thing I tried is to if fix mbr via Command Promt and bootrec /fixMbr command.

There aren't solutions that worked for me, so help would be appreciated.

A:Windows 10 boot error - black screen with blinking cursor

Ubuntu can mount the windows partitions and you must be able to read the contents.
I feel your windows partitions need dskchk
you must have a gparted program. or you can install it.
I hope you can do a check of the partitions . if it does not show the partitions you have more problems than you think.
do not commit any thing with the gparted unless you are sure.

I saw this ad on craigslist for a free monitor.

The following description follows:

The model is a Dell UltraSharp 1702FP. I don't know exactly what's wrong with it; about two weeks ago in the middle of use, the screen suddenly went black and the LEDs started flashing in a pattern.
any ideas?

This evening I decided to reboot my personal computer, which uses Vista. Up until this point it had worked fine, including earlier today. Every time I attempt to reboot it, it starts by bringing up its normal white screen about being a gigabyte motherboard. It then never shows any of the data involved with the reboot - instead, it goes straight to a completely black screen, and stays on it indefinitely. There is a blinking green light on the monitor. As the light blinks, there is a faint "clicking" or "flickering" sound.

I have attempted multiple computer restarts, adjusting the monitor cords. None of it has had any effect. There is no error message, at least not that I've had the ability to see. As I cannot see anything happening on the screen, I do not know if this is purely a graphics problem or if there is also a problem with the computer.

Thanks in advance for any advice...

Im new here so sorry if this is the wrong place to post this.

Here is my problem:

I have just recently purchased a new Philips HDTV (32") and I have connected my pc to it via hdmi. I use a dvi-hdmi converter via the DVI port on my graphics card (NVIDIA XFX GeForce GTX 260).

The screen blinks and changes to black for a second usally displaying no signal or unsupported format in the top right hand side of the screen. Then it switches back to normal. The blinking happens randomly but never takes longer than a few minutes to happen.

I have all the latest Nvidia drivers installed.

One more thing I had a 32 inch tv before this one and it worked ok. It had issues with the text being blurry and it ended up blowing .

But any help would be really appreciated!

Thanks in advance!

I have a Dell Inspiron 6000 running XP Pro. This morning I received an error code M1004 (something about overheating) and the computer was frozen at that point. I cleaned out dust from the heat deck, as it was completely blocked with dust. I also did a hard shut-down then restarted, and all I get is a black screen with a blinking cursor. I can only use F2 or F12. I've tried running diagnostics with no help. I upgraded my BIOS with no luck. I also tried to run chkdsk from the XP repair module, and I'm getting a message saying that one or more volumes have unrecoverable errors. I also get a directory enumeration error when I try to use the dir command on the C drive. I'm trying to figure out what to do now, as I unfortunately didn't back up about 1 GB of pictures that I need to get off this hard drive. Please help. Thank you!

You can pull that drive out of the computer and put it on another computer as a Slave drive or buy yourself a USB enclosure and put the drive in there and you will be able to copy your pictures and any other valuable data. Then either buy a new drive (as this one may be bad) or put it back in and Boot off of the XP CD, Format and reinstall.

hello. as the title states, i have a windows 7 pc that won't boot past a blinking cursor on a darkened screen. it went through a chkdsk /r and lots of different things that took 50+ minutes; renamed some, deleted some, then rebooted. nothing. i went into the registry and opened a hive and made sure the bootup went to explerer.exe -- nothing.

then i decided to take some files off the drive from another pc. when i plugged it in, explorer showed a 'system reserved drive' (in my case, m and a 'local drive' (n. when i click on m:, it shows it to be empty, and when i click on n:, i get the window, 'n:\ is not accessible, access is denied' but does show there to be data on it.

so, then i right clicked on both drives and changed the security to allow everything for SYSTEM & Administrator (see, read, modify, etc.). i know i have admin rights to do this and everything is running smoothly, as all the files appear to be getting their attributes changed. now, i right click on both drives and see i have full rights...but i STILL can't see or access the files on n:! i can see the files as their attribs are being changed one by one, so i know they're there, but i can't manipulate them in explorer.

for some reason I can't even get into windows 7, after I get pass the screen that says "asus" , my laptop brand, It goes into a black screen with a blinking cursor in the left hand corner like this:

A:Can't get into windows, black screen with blinking cursor

Hello grive and welcome to Seven Forums.

Have you tried booting into Advanced Boot Options? As soon as you start your machine click the F8 key (top row of keyboard) and keep clicking until you see the Advanced Boot Options screen. This tutorial has a bit more info.

Advanced Boot Options

From here you should be able to choose from several different options including Safe Mode, Last Known Good Configuration, etc.

Depending on your specific computer you may also have a hidden recovery partition that can return your machine to factory specs (just like the day it was when you got it home.) On some laptops you can press F9 at start up and that should open the recovery process. I believe you get four different options:

1. If none of the following recovery options is selected, the computer will just be rebooted to load Windows (if Recovery is started from the hard drive) or run the bootable disc in the optical drive.

2. The first partition is deleted (the others remain intact) and a new system partition C: will be created.

3. This option removes all the partitions from the hard drive and creates a new system partition C:.

4.This option removes all the partitions from the hard drive and creates two new partitions C: (60% of the drive’s storage capacity) and D: (40%).

You might want to check your owners manual or quick start guide to see if it gives more info.

Hi all,

I was hoping that someone can guide me through resolving this problem that I think is related to Windows XP.

I have an old Thinkpad T42 laptop that stopped booting up, but instead would go to a black screen with a blinking cursor on the top left-hand side. I tried booting from a CD (after changing the boot list), but that didn't work and also tried using a repair CD but that didn't work either (i.e. nothing showed on the screen). At some point much later, when I started up the laptop it went to the IBM thinkpad splash screen and then to a screen that says:

Error 0271: Check date and time settings

Press F1 to Setup

I've read on the internet that this issue is likely caused by a bad CMOS battery so I ordered a new one.

What I wanted to know before replacing the battery is:

1) Could that have caused the blinking cursor/black screen problem as well or is it more likely a virus that corrupted the Master Boot Record or perhaps I have both problems?

2) Would it work if I just swap out the hard drive and use the hd from a Toshiba Satellite C870 laptop either internally or somehow externally? The Toshiba powers up but the screen is cracked so I cant use that laptop now either!

I just want to be able to use the Thinkpad until I replace the Toshiba and am looking for the easiest solution.

Appreciate any suggestions.

When i tried to do this this time and i chose install my computer says that it cant read the disk.

When you put the windows CD in did you change the BIOS to 'boot from CD' first?
If it is set to try and boot from the Hard Drive before the CD it probably wont even look at the CD.

I am using Windows 8.1 with all the latest updates.

I'm trying to get into safe mode, but when I do it is only a black screen with in each corner it says "Safe Mode" and the whole screen blinks every few seconds resetting the cursors position. The cursor and text are only visible when I am moving the mouse, otherwise it's all black. I can't do any button combinations like CTRL ALT DEL or anything.

Normal mode works fine, and I can't think of any viruses/malware that work allow you to work in normal... but not safe mode.

I have all my W8 options disabled (Windows 8 mode, fast boot, secure boot) to see if it was those but to no avail.
Everytime I try, I have to go into safe mode. It sticks, so I can't just reboot/reset and go back into normal mode. I have to go into the emergency cmd and do bcdedit to delete the safeboot value.

I usually clean my PC every so often, the same with OS re-installation but nothing is wrong with the normal mode and the OS still seems quite fast with the SSD.

I have never seen safe mode function, this is the first attempt at running it in safe mode.

Anyone have any ideas as to what could cause this? I have seen a few threads on others experiencing it but most are Window 7 or older and they are all in normal mode and they can't get into safe mode to fix it... I can't get into safe mode but can get into normal mode...


A:Safemode is black screen with blinking mouse. *Windows 8.1

To be honest, I have never seen this.
The only thing that comes to mind is incorrect display/graphics drivers or the graphics card is crapping out. Check also the monitor driver.
It's unfortunate that you are unable to access Device Manager in safe mode, or are you, to see if any yellow exclamation point or red "X"

A:black screen with blinking cursor tried installing Windows 7 again

Hmm just so I have it right you cannot install 7 back on the drive you put the Linux OS on? Plus have you any data you need backed up? Because I reckon that you will need to complete wipe that drive using diskpart clean all or Partition Wizard - wipe and reformat it before you can do a proper install.

To reinstall this is a good way of doing that and gets the freshest ISO of the version of 7 that you had originally.

I have a Dell XPS 8300 desktop running Windows 7 Home Premium 64-bit. Last night, I was checking Hotmail, and then I left the computer for about an hour. Upon returning, all I saw was a black screen with a blinking cursor in the upper left corner. I have no idea what happened while I was gone, nor the sequence of events that occurred resulting in this black screen. I have tried restarting the computer, but I keep ending up with the black screen/cursor.

Here?s the sequence of events I experience when attempting to restart:
1. Press power button
2. After a few seconds, I see a circular Dell logo. A blue status bar at bottom advances fully from left to right. Also on this screen are instructions in the lower right for F2 (Setup) and F12 (Boot Options).
3. Finally, it ends up on a black screen with the blinking cursor in upper
left corner. Sometimes, before the blinking cursor appears, it will say ?keyboard failure?, but often times it doesn?t say anything at all, and just goes straight to the cursor.

I have tried both the F2 and F12 commands, but honestly, I have no idea what I?m looking at nor what to do once I get into those options. In the F12 command, I did get into a Diagnostics screen. It ran an extensive check called ?Dell ePSA Pre-boot System Assessment ? Service Tag GLQ1FP1? which took several hours (I let it run overnight).

This is my first time posting here. I've noticed that many people appear to have had the same problem, but when I read the responses, I can't seem to find one that fits mine in particular (perhaps I just don't understand how to implement them).

When I hit the startup button, I get the IBM thinkpad logo and "to interrupt normal startup, press the blue access IBM button" and then the screen goes black with a blinking cursor on the top left hand corner and Windows won't load. Out of frustration, I tried re-arranging the boot priority order and network boot priority order but returned them to the default settings because I'm not technically proficient.

I also tried following the instructions for getting into safe mode (from the microsoft site) but hitting F8 doesn't work.

This problem may be virus related because I got an avast warning yesterday that it detected a windows32 malware and moved it to the chest. I declined the option to restart at the time - I was working on some stuff - later, I inadvertantly put it on standby without scheduling a boot scan on startup. Anyway, next time I tried to boot up I started having this problem.

I did have the windows security 2011 virus two weeks ago and managed to remove it but I don't know if this is related.

I have a Dell Inspiron with Windows 7 which was infected by what KasperskyTDSSKiller called the Pihar.c rootkit.  I selected the 'cure" option and was prompted to reboot the laptop to complete the removal process.  Upon a reboot, the Dell logo appeared and then the black screen with a blinking cursor.  After researching similiar situations in the Bleeping Computer forums, I created a Windows 7 system repair disc from a clean machine but have been unsuccessful in getting the machine to boot from the CD.  Unfortunately F8 nr F12 don't do anything when pressed.  The initial Dell logo screen suggests that F12 should open the boot options but it doesn't recognize any of the F keys.  The only thing I can do is press Ctrl Alt Del, which restarts my computer.  Any suggestions on how I can get past the black screen would be greatly appreciated.  Thanks.

Hi everyone,

I need your help/suggestions on this one before I do any harm to the system.

The problem is my DELL E310 will not boot to Windows XP. It got as far as the DELL Logo and then it comes to a blank black screen with blinking cursor on the upper left corner.

At the DELL Logo, I can F2/F12 to change the boot sequence and boot to Windows XP pre-SP1 Install CD. I have tried going into the Windows Recovery Console. Typing "dir" gets a "An error occurred during directory enumeration" for C:drive. Typing "chkdsk" gets a "The volume appears to contain one or more unrecoverable problems."

What was I doing before the blinking cursor...? I was trying to set up dual-boot configuration with addition of a 2nd SATA hard drive. Before attempt to install XP on new drive, a quick check in Control Panel | Computer Management | Disk Management confirmed that Windows was seeing the new drive:
Disk 0 (existing C:drive) 144.33 Gb NTFS, 39 Mb FAT and 4.64 Gb FAT32.
Disk 1 (new drive) unallocated.

I tried to install Windows XP to the new F:drive (after creating the partition), but the installer wants to install to C:drive instead. On the installer set up menu, it reports Cartition [unknown] 132 Gb.


A:Blinking cursor on blank black screen, Windows XP

Use your windows install cd and get back into the Recovery console, instead of chkdsk, run the FixMBR and Fixboot commands. In all instances that i've encountered the "blinking curser", it's been a corrupt or modified MBR record.

I'm resigned to the idea of re-installing Windows 7 and starting from scratch, but that's a pain. Is there any way to fix the boot sector through the command prompt or another back door way to repair Windows?

Unfortunately, the post that I have linked is no longer applicable (to me), because the person in that post decided to reinstall his/her OS.
Whenever my computer starts up, it is automatically directed to a blank, black screen save for a blinking white cursor on the top-middle of the screen. The Windows logo animation screen does not even appear, it just skips to the aforementioned black screen. I have so far waited about 12 hours for something to happen, and of course nothing happens. I am not redirected to Startup Repair or anywhere else after any reboot.
I recall that prior to this, while I was trying to organise some of my files, my computer suddenly decided to close all programs and shut down on its own for no conspicuous reason.
Once again, system restore points do not work, and I am unable to use Safe Mode or any of its variations, because the computer won't let me do so. Malwarebytes and Spybot are my antivirus programs installed, and the solution of reinstalling the OS itself is off-limits to me because I am unwilling to see the extinction of all of my personal stuff.

A:Windows 7 frozen black screen with white blinking cursor

I apologise, I just realised that I forgot to note that I am unable to provide a FRST.txt log for the computer this time because I am unable to get into Advanced Boot Options. No matter how quickly and repetitively I tap the F8 key, the black screen always manages to come first. I should also note that the white blinking cursor starts off from the top-left corner, then dashes to the top-middle after about a second passes. So consequently, I am unable to get into System Recovery Options and run any program through Command Prompt.
I still await any possible instructions. Again, I apologise if I sound impatient.

Hi there,
I have ACER 5745 Model, and have windows 7 ultimate and Linux OS on my drives. Windows 7 is in C drive and Linux is in E drive. While I was working on my windows 7 system, the electricity went off and since my battery is dead, so my system shut down immediately while I was working on internet. Well this thing has happened many times before but every-time I was able to restart my system. But since last time whenever I am trying to boot my windows only a black screen appears with an underscore blinking in top left corner. I have later on logged into Linux to check whether it is functioning or not, and it is working fine, but when I try to log into windows it does not boot up. When I press power button, it goes past POST, till the point where options appear whether I want to choose Linux or Windows. When I choose Linux it works fine but with windows the problem of black screen with blinking underscore appears.I have tried everything from using F2 and going into 'set up' , pressing F12 and going into 'boot', but nothing seems to work. I have tried F8 to check into safe mode but of no use as safe mode doesn't appear even after repeatedly pressing F8. I have then checked "Memtest 86" and have done 11 passes.

HI, I am unable to boot into windows 7 in either safe or normal mode, All options using a win 7 boot disc leads me to a System Recovery Options screen where the keyboard and mouse pointer are frozen and my options are diminished.
What i believe has happened is my son has informed me he was trying to install a game and needed winrar to extract the contents, The file he was trying to install brought the AVG virus program to life. Viruses were quarantined and files deleted.
This was yesterday evening. When I tried to fire up the PC this morning the black screen is as far as i could get.
The PC in question is a HP Touchsmart 610 all-in-one with Intel i5 and 14gb ram.
It is used daily for my work as a freelance graphic artist.
I was prepared to format and re-install but i cannot even find a way to do that at this stage.
I would really appreciate any help to sort out this problem.

A:Unable to boot into windows 7 Black screen + blinking cursor

Instructions for a Windows 7 Repair installation.
A Windows 7 Repair Installation will require a installation disc.
If you do not have a Windows 7 installation disc you can download a free legal ISO image of Windows 7 SP1 at  Windows 7 Forums.  You will need to download the same version of Windows 7 that you have installed,  This image is hosted by the Digital River store which is an official distribution partner of Microsoft.  This is a genuine untouched image which is safe to download. 
Attention:  If you do have a Windows installation disc, skip Part A and go to Part B, Step 1b.
Part A, Steps 1a - 6a
The ISO image will need to be burned to a DVD in order to create a bootable installation disc.
1a)  To burn a ISO file to a DVD please download ImgBurn and install it.
2a)  Insert a blank DVD into your CD/DVD drive tray, and then close the tray.
3a)  Open ImgBurn, and click on Write image file to disc.

4a)  Click on the Browse for a file icon:

5a)  Locate the ISO file you want to burn, and click on the Open button.
6a)  Click on the blue arrow to start burning the bootable DVD.

Please note:  In order to boot from this DVD you may need to change the boot order in the BIOS so that the CD/DVD-ROM is the first device in the boot order, and the hdd is the second device.

Hello everyone. First of all, I would like to start off by saying I love your forum here. I have used it many, many, many times in order to resolve a problem I encountered here in our computer repair shop, so much props goes to you guys.
We have a customer's computer running Windows XP Professional that will not boot. After the Compaq splash screen, it simply hangs at an all black screen with a white blinking cursor in the upper left hand corner of the screen. I have already searched your forums as well as poured over Google searches and tried various things. The things I have already tried to no avail are:
1. Boot into Recovery Console from Windows XP Pro CD and fixboot/fixmbr
2. Replace RAM with new RAM.
3. Replace NTLDR file from a working Windows XP Pro machine
4. chkdsk /r
5. Used a guide here on your forums for using xPUD with mbr.bin on a USB. Not sure what was supposed to of happened, because nothing did after I followed all the steps. Completely unchanged.
6. I have also tried booting into Safe Mode, which also does nothing.
Finally, out of my own frusteration, I booted the computer to Hirem's Boot CD and used it's "Fix NTLDR Is Missing" tool using the first option out of 10 possible fixes and wham! Boots Windows first try. However, upon restart of the customer's computer I am again greeted with the black screen and a blinking cursor. I must use Hirem's Boot CD to boot Windows each time.
Obviously one would assume it's an NTLDR issue, but... Read more

Dell Inspirion E1750 with Windows XP Media Center edition...

I had gotten several blue screens of death previous to this ultimate meltdown (usually while being on facebook)

One day, while I was facebook, my anti-virus software (AVG) popped up saying I had malware and it was quarantining it. After the quarantine, the program said I had to restart, so I clicked OK for the restart.

Then the computer never restarted. It shows the Dell screen, but then doesn't get to loading Windows. It goes to a black screen with a blinking underscore in the top left corner.

I do have the ability to get the BIOS, but that's about all I can do with the computer to my knowledge at this point. I am posting this from another computer, so I can't run any of the programs suggested to diagnose problems.

Is there a way to save the computer? Is there a way to save the data on the C: drive? Hopefully both?

It sounds like your hard drive may have been corrupted. Do you have a Windows recovery CD?

If so, try to boot the computer on the windows cd and select Repair. This will attempt to repair your current windows installation. Hope that helps!

Hi guys,

The other day I was using my old desktop and using firefox when suddenly firefox froze up while browsing and I was unable to ctrl+alt+del or click start or anything for that matter in order to close it down. I then turned off my computer manually by pressing the power button as I sometimes do when my computer freezes and turned it back on. Unfortunately, when I turned it back on the computer is stuck on the black screen with the blinking underscore in the top left hand corner.

I unfortunately am not good with computers and would like to avoid reformatting my computer, as this old desktop contains the largest amount of my media such as music and movies that I had been meaning to put onto an external hard drive. Furthermore, I do not have an XP installation disc and am unable to locate the system recovery discs that came with the PC (like I said, it's old, circa 2006, and they are most likely lost somewhere in the house or thrown out by now). Thank you for all the help and support in advance.

A:Windows XP black screen with blinking underscore in top left hand corner

if you haven't tried, as you switch on press the F8 key up and down repeatedly, if this works you will be at the safe mode menu - try last known good config. If still no go, try booting to BIOS - if this doesn't work I would say hard drive issue. Download the hard drive manufacturer's diagnostic program, this has to be burned to a disk. Then put the disk in and let it boot the pc and run the test.

Hi I made a thread yesterday regarding a minor PC problem I had while trying to install windows XP on my uncles PC the problem was solved thankfully.

I now have an even bigger problem of my own with my PC.
I turned my PC on in the evening and the monitor screen was blank and displayed a blinking orange light, the fan does come on. I doubled checked the wires to see if any were loose but everything is inserted correctly.

What&#8217;s weird is the PC that I was installing windows on yesterday was doing the same thing but once you turn it off and turn it back on it would be fine and load windows.
But my one is not even doing that, there is nothing wrong with the monitor has I have brought it recently and I also checked the PC using my brother&#8217;s monitor and the same thing happens.

Once I finished installing windows on my uncles PC I turned my PC on and watched highlights of a soccer game so it actually was working last night. But I have no clue as to what has happened?
Can someone please help me?

I'm not very knowledgeable when it comes to computer, ah, specs (or finding information about the one I have)... so I don't have much for you to go on.

Computer is a Dell, with Windows XP Home Edition. Monitor is LCD.

A few days ago (around Wednesday morning) my monitor began to click on and off. The screen would flash black and the light, next to the on/off button, would flash from green (on) to yellow/orange (off). At first it wasn't that bad. When I switched pages on the internet, scrolled, or highlighted something on the page it would flash.
It steadily got worse, going from internet pages to flashing on and off right when I turned the computer on, all through the loading and welcome screens.
I thought maybe it was just the monitor, so I switched it out and hooked up my old hp pavilion mx70 monitor.

That monitor worked perfectly fine with my old tower, but when hooked up to my new one it... Erm, got 'static-y'. It looked like an old TV that had a VHS tape in the player, being re-wound. I know that sounds odd, but it was like spikes from the side of the screen surging inwards. I thought it was because the monitor was so much older than the tower. Soon the static got steadily worse, and I used it for about a day before it got to be too much.

I switched to Safe Mode with Networking on the hp monitor, to see what would happen, and it was fine! No static. Today, I switched back to my LCD monitor and put that into Safe Mode with Networking and no b... Read more

A:Solved: Monitor or Tower problem? Monitor is blinking on and off.

Video card is busted. When in safe mode, the video card's drivers are not loaded, so the card does not function at "full blast". It will not cause trouble because of that.
Dell model would help finding a replacement, but it can well be assumed that there's a PCI-E 16x slot for add-on graphics. This would be a cheap replacement in that case:

This is all an assumption on the most propable cause. The problem could also be your power supply or motherboard, but those are pretty unlikely.

My OS:Windows Xp, Home edition.

Starting off, a couple of days ago while browsing facebook, and logged into starcraft II. I started getting screen static and then a blue screen to a shut down. The blue screen error was explained by a nv4_disp. Which I googled and seems to be a video card error.

I did a file recovery and had a friend of mine reinstall all the motherboard drivers and 90% of the drivers needed to run my pc. The only one we didn't install was the newest version off the nvidia website. Due to a time restraint. So we just downloaded the regular drivers that I recieved when purchasing the 8800 GT GPU. (The disc). When I got home I wanted to make sure all my drivers were up to date so I proceeded by going to nvidia to get the latest driver for my 8800 GT. 5 minutes after the complete install while browsing the web looking for latest drivers off all my hardware, I got a blue screen again. This time not explaining but just flashing and shutting down my computer.

Now I know this is what was suggest, and this is what I did.. so should be a easy fix right? --> boot safemode uninstall and reinstall newest drivers for my video card. (8800 gt).

But it didn't take the "newest" updated drivers. But handled fine for several hours with the (disc drivers recieved with my GPU), while installing the rest of the drivers/networking etc.. with my "IT friend".

Now I'm wondering if I should uninstall the video drivers I installed and then proc... Read more

Ok so this is what happened.

I was playing Assassin's Creed when all of a sudden the game freezed and an error message popped up which said that the nv4_disp.dll has stopped functioning. It is at this point that the computer completely froze. I waited 2 minutes for the computer to work again but it didnt so I forced the shutdown.

Upon restarting, my computer would go past the Windows XP boot screen as normal but then after that it would just turn black and stay black even though the monitor is on.

I rebooted into safe mode and uninstalled the nvidia drivers and rebooted normally. It worked!
When I reinstalled all of my drivers, I rebooted my system and the EXACT same problem happened again. I tried this again one more time but to no avail. So then I went into 'Last known good configuration' and here I am now surviving on 1hz refresh rate.

If anyone can help me get my display drivers functioning again I will be unbelievably grateful so please help me somebody.

This is called artifacting and it is a strong sign that your video card is dying with the exception that it may be an overheating issue. Is the fan on the card working? How is your PC's airflow?

My best guess though is the card is dying.

Alright, I've been trying to play Bioshock for about 2 days now and haven't gotten any further than 10min. into the game before getting the BSOD. It references the infamous nv4_disp.dll error. My specs are:

Pentium M 2.0GHz
Windows XP Media Center (SP2)
1gig RAM
NVIDIA GeForce Go 7800 GTX (it's an XPS laptop)

I don't thnk my comp is running out of RAM, I have RAM Idle and it never shows that I'm running too low when Bioshock is running. I have Forceware 84.69, I think it was the last they made for the GeForce Go series.
Dunno if it's relevant, but I reformatted my HD about a month ago, and had accidentally installed Forceware 163.71 for a while (it's for GeForce 7800 but not GeForce GO 7800, the laptop version). It ran with a decent amount of stability, until I tried playing Bioshock.
I know my specs are a little under par for this game, but I've gotten several minutes of good gameplay so I know my machine is capable of running it, I just don't know why it's hitting this BSOD most times I go to a loading screen (which happens often in the early parts of Bioshock).
I'm willing to try anything, talk to me people.

However, in my quest to solve that problem (IRQ more or less error message) I updated my graphics drivers to the 94.24 forceware. Since then I'm getting a new error message. nv4_disp.dll. I have a BFG Nvidia 7800 gs oc graphics card and I'm running win xp sp2. rather than simply rolling back the graphics driver I was wondering if anyone had a recomendation for a specific driver thats particularly solid.

as always thanks so much for all the help


A:nv4_disp.dll error message

Try updating it again to maybe a later version of forceware???

I have a Pavilion 23xi that has recently started to go black (blank screen) after being on for a while.  The power switch shows white (on) and becomes  unoperational.  The only way to get it back on again is to remove the power cord on the back of the monitor and replug it in.  This will work for a while and then will do the same thing over again and has become a pain.  The monitor is fine otherwise.  What can be done to fix this problem.  Please advise, thanks

I upgraded my pc with a 120gb ssd from a 500 gb HDD. I installed Windows 7 on the ssd and formatted the old drive and thus removing its windows installation, however i did not remove the 100 mb system partition (did not know how to).

When I restarted the computer it showed a black screen with a blinking line in the top left corner, at the same moment it ussualy displays the windows startup logo.

I disconnected all other drives but my ssd and reinstalled Win 7 after having formatted it. It worked fine for hours, and I was able to boot without problems. I had disconnected all drives but my ssd while installing windows 7 but when i reconnected the old drive (on which there was still the 100 mb system partition) the black screen with the blinking line was back. The ssd is in sata1 and Bios sees all drives.

it would be great to be able to resolve it without reinstalling windows a third time.

thank you very much in advance.

My system has Windows XP Sp3 installed.

My video card is an Nvidia Geforce 9800 GTX.

I have no BSOD or problems whatsoever. I noticed there were new drivers so I went to download them.

I installed the new drivers and upon restart got BSOD at the windows loading screen involving "nv4_disp.dll". I believe it was 0x00000050.
Anyway, I didn't install the new driver in safe mode, nor with antivirus disabled. Would this cause the problems?

I rolled back the driver and no more BSOD.

The only reason I wanted the new driver is because I was hoping they fixed it in the nvidia control panel so you could select "dual view" with 2 monitors, instead of only "clone" view being available.


A:BSOD nv4_disp.dll error after installing new NVIDIA drivers

you can try uninstalling the driver you have now and then installing the new one.Just make sure you know what version you have now. Just incase you have to revert back.
You should always uninstall a driver before installing a new one.

Hello Everyone,

I will try to keep it brief (fat chance), hence the list. BTW, what is the prize for the longest post in the history of the forum? I prefer cash.

1.Thanks for making this fantastic forum available and for all of the help you provide.

2.I noticed several Vets, and maybe there are actives among you? I spotted one person that is a gold star parent. Thank you all for your service and the sacrifices you and your loved ones made to keep us, and most of the world, free.

None worked for me so here I am. Yet another among the needy.

Here is a list of before the problem, the problem, and what I did to attempt a fix.

1.Battery near collapse. Said fully charged but only lasted a very short time before low batt alert.

2.Updated Java JRE 32 & 64 and plugins for FireFox and IE. It was a struggle. Finally went to for a utility that succeeded.

long story incoming :9

Okay well I recently restarted my computer and was stuck with a black screen with a blinking __ after my video card bios popped up.

So I kinda freaked out and restarted it again trying to get into safe mode, did not work at all so I restarted it again and left it on.. nothing happened so I walked upstairs to go on my laptop to think of some stuff that went wrong.. I probably left for a good 25minutes..

I figured my harddrive died/my windows OS got corrupted because nothing was booting.
Came back downstairs and restarted it again... and now it is properly working..... my problem is I'm kinda afraid to restart it again and have it not properly work..

is there anything I can do to backup my data like move to somewhere safe on my hd if i wanted to reinstall windows?

I have everything on the C:/ Partition which means if I wiped it I would lose everything if I'm correct and i have a good 25gigs of music and games I would hate to re-download/install.

and the last question is if i was to just buy another harddrive could i use this one im using now as a slave even if it has windows on it, it wouldn't boot the windows and i could get the data off of it?
perphaps nothings wrong and is was a fluke??

I'm sorry for causing trouble but i really don't know what to do. My last resort is to reformat and i was hoping it won't come to that.

My PC is a pentium 4 windows xp.
it was doing fine a week ago until i noticed that the screen randomly blinks like it turns on and off but the monitor does not turn off its just the screen that turns black. It happens randomly. at first it rarely happens like there are days when the pc didn't have anyproblems at all. and we ignored it but now its starting to get frequent. what's worst is that the PC hangs a lot specially when i use the internet or photoshop.

the blinking starts it happens during while i'm downloading a site or doing something in word or photoshop. i think when the pc is the screen turns black then comes back again. i hope i'm not confusing you guys i am trying to explain my problem to the best of my amatuer abilities

Hi, I seem to have gotten a nasty virus and now when I start up my computer the correct display background will appear, but there will be no start menu or icons. Instead, there is a black box with a blinking cursor inside it called C:\Windows\System32\cmd.exe
I have a Dell Inspiron e1505 and I have all school information and pictures and I really don't want to have to buy a new computer. I tried scanning my computer with Avast!, which has worked fine for me in the past, but the virus is no longer letting me run it correctly (it says there are missing components that won't allow it to run properly). I tried Spybot Search and Destroy which got rid of a ton of viruses and spyware (I did this in Safe Mode which works fine), and when I tried to start up again the black box problem came up again.

So I was using my (obviously) XP desktop, a Dell Dimension 5100C. I've had it for a few years, and to my knowledge have never opened it to add new parts or anything. Today when I was using it, it randomly turned off. Now, whenever I turn it on, i get a black screen and a blinking underscore. First, it loads the Dell logo and gives me two options: F2 and F12. I tried F2 but I couldn't really find anything. Then I did F12, the boot menu. It listed 2 options: Onboard SATA hard drive, and Onboard USB drive. I tried the first option, and it just froze on that screen. I tried the second, and it said that the drive was not found. I really don't want to format the harddrive since I have sensitive information on it. Any ideas?

A:Black Screen with Blinking Underscore

i believe your hard drive is dead

even if you did run the reformat disc it wouldnt do anything.
but if you want to test it put in your recovery disc and continue thru the options but stop before it actually starts wiping the drive.
if it goes anywhere you have a different problem
but if it doesn't detect any drives than its dead

I have a HP G60 laptop. When I power up, I just get a black screen and a single cursor that doesn't blink. I doesn't even show the the logo for windows or HP / Compac. No buttons respond, except cntrl.alt.del. and that just flashes the screen for a moment, then back to the black screen again. I would send you more specs but I can't get to them. Thank you in advance for your time.

A:black screen, NON blinking cursor.

If you don't see the HP logo, then you've probably got a video problem (although other things can cause this).
Start by trying an external monitor on the computer to see if you can see the HP logo when it boots.

Beyond that there's not much else that you can do. Maybe take it to a local shop for an estimate?

HI, could i have malware problem?
XP SP3 Gateway E-4100 desktop running fine usually, occasional slow-downs...
but yesterday the OS wouldn't load. black screen with blinking and i could get into the BIOS screen, but couldn't figure how to boot in safe mode. changed boot order to CD first.
Tried using Gateway original OS install CD; it would spin, show the Gateway green screen and make its video adjustments, then turn black again.

The only change i can think of is that we received a warning email from Comcast ISP reporting a pc on our home network had a BOT infection; didn't say which pc; we have three dekstops and 2 laptops; XP, vista, and 7.

Thinking i needed a new pc, i removed the printer usb cable to insert into a working desktop; and ingnored the gateway.
also removed a wireless mouose usb receiver.
hours later i thought i'd turn monitor back on and try to boot up again; and it showed black screen with "mouse and keyboard settings are not active"; but did allow me to boot up with hard drive, and pc worked as if there had never been a problem.
I assumed that unplugging printer cable or mouse receiver from usb's had fixed the problem; but same devices had been in use for several years.

Hello and sorry for the generic title:
Recently my computer closed all programs and continued to shut off. When it came back on, it was able to get past the Dell Logo Screen but could not continue to the login screen, instead it loaded a Black Screen with a Blinking "underscore" cursor on the Top Left-hand of the screen.

Prior to this, a process called "svchost.exe" used an abundancy of memory and caused my computer to lag very badly, I found that while "svchost.exe" is a commonly used, important Windows process, many viruses and trojans can disguise themselves by naming their process this. I used a program called "Process Explorer" to ultimately "Suspend" the Process right before it used alot of memory, and I was able to use my computer without problems from then on.

While trying to solve my Black Screen issue, I found a Thread on the hp forums that had a similar, if not exact, replica of my issue. The link is here:
Black Screen w/ Blinking Cursor - HP Support Forum - 1330837

I thought it was weird that with the Black Screen I had, I only had to press the Power Button once to turn my computer off, rather than hold it down. Ultimately, I followed DavidPK's solution, created a Windows 7 Recovery Disc, and as I was trying to presumeably reset or rebuild my BCD, I found that my Black Screen issue had not been solved.

A:Black Screen with Blinking Cursor

Hi tracethom,

From your description, the issue appears to be 'software related'. Since the system goes past the 'Dell logo', it may be a corruption on the 'Operating System'. However, I recommend you to run 'hardware diagnostics' to check 'hard drive' functionality. This will eliminate the possibility of 'hard drive' as the root cause of this issue. This becomes even more important, as you've mentioned about the system shutting down on previous occasions.

To run 'diagnostics', restart the computer > Repeatedly tap 'F12' key at 'Dell Splash Screen' > Use 'arrow key' to highlight 'Diagnostics' > Tap 'Enter' > Capture error, if any and share details.

You may also try the following steps (If the diagnostics pass) to see if they help:
1. Unplug all devices from the system and release the static charge: Unplug all the external peripheral devices from the system (USB Devices, Monitor cable, Power cables, etc) > Press and Hold down the 'power button' on the tower for 10 seconds continuously > Plug the 'power cables' back in > Plug the monitor cable, keyboard and mouse > Try powering on the system only with the basic (essential) devices attached > Repeatedly tap the 'space bar' at the 'Dell splash screen' > Confirm 'Delete Restoration Data' if prompted.

2. If the issue persists, restart the system again > Tap 'F2' key repeatedly at Dell splash screen (BIOS screen appears) > Check if the 'Hard Drive' is detected here (Capture and share the detail... Read more

I'm sure you've heard of this before, but let me assure you I've tried all the steps the previous topics had to offer. This is a windows xp problem and a ubuntu problem as well.

So, I installed Ubuntu 9.10 32 bit on my Gateway laptop, and it kept crashing because the filesystem would never load. Again I reinstalled the OS two times, until GRUB crashed as well. While I was doing this, there was a 20GB partition on the hard drive that never showed up on GRUB, it was my old windows xp service pack 2 OS. I haven't been able to access it since I installed ubuntu. So, I took a service pack >>3<< disk and I deleted the ubuntu partition and installed the OS on that. It installed, but after I enter my BIOS password, the blinking underscore is still on that screen, and it just does that forever. Doesn't boot, doesn't do jack ****. Oh what should I do, gurus of computer wisdom...?

I purchased a used computer on was supposed to come with Windows XP installed. When I started the computer, it showed an error message saying something to the effect that there was no operating system.

So, I tried to boot it off of a Windows 98 boot disk. Then I checked the BIOS to make sure it was starting in the right order.. and it seemed to be.. but this is way over my head.

After that, I ran fdsk thinking something was corrupted since as I said the computer was supposed to have XP installed.

Well, after I ran fdsk, all I get is a black screen with a blinking cursor.

So, I emailed the seller of the computer and he sent me a new Windows XP professional CD. Not pirated. I put the CD in thinking the computer would recognize it but nothing is happening. Just a black screen with a blinking cursor.

I have no clue what is wrong or what needs to be done.. please help! This computer is an HP 512C with 256 megs of ram, 1.7 celeron, 40 gig hardrive...

Thanks for any help.

Ok so I have a Compaq EVO D51S running Windows XP Pro but whenever I turn it on it goes through the first two (boot options then logo) screens, then I'm stuck with the black screen with a blinking cursor, I'm going to try changing the CMOS battery in an hour or so but have a feeling it may not work, I've tried booting a Windows CD to put a fresh install on but I get the same screens, any ideas?

will it let you type anything in? If it does allow you to type in words, type the word "help" and see if a list of msdos commands come up.

I entered the administrator password given to me and it worked to get me past the "system disabled" screen, but it only opens up a blinking cursor on a black/blank screen.  What must I do now?  Please advise.  Thank you.

I have already posted at the Expert Exchange, but I am getting no traction there so I am thinking of reposting here.

All the tech spec are in my post below, but I wanted to summarize the problem so that it wasn't such a chore to read:

Basically, I had 3 drive, each with one OS: Win XP, Vista 64 and Win 7 64

For some reason the Drive with XP crashed and it's dead. Now I am trying to revive my Win 7 Disk but all I get is the same blinking cursor on a black screen. Each time the repair disk that came with my Win 7 upgrade tells me that everything is OK but each time I try to reboot I end up on the blinking cursor.

The reason the machine crashed is pretty clear: The win X{P drive was booting the rest of the OSs. Now that's gone the Vista and win7 drives don;t have a valid boot loader. The repair disk seems to think everything is fine, but it isn't.

It has been suggested to me to use BCEDIT : BCDEDIT - How to Use

But in iorder to use it it would have to be installed on the disk.
Does anyone have any ideas? Thank you.

hi, i updated my windows 7 laptop today and when it restarted i was faced with a black screen and a blinking cursor in the top left. It was working fine before. I have inserted the disk and booted it and was able to get a repair screen but when i do a startup repair which says it hasnt found any problems. I have also tried restoring it to 2 days ago but even though it says it worked i still have this black screen. All i can get is a setup manager and a boot chooser. Im not sure if the setup manager is bios. I can get a command prompt when i boot the cd. I can only boot the cd if i press f12 on startup and choose cd/dvd. Please help :S

A:what causes a black curser to start blinking

hello ,

your system could be infected ith maleware

do you have a Windows Xp cd, not the restore cd's that come with some systems, the cd will have the Windows logo & 3D hollowgram/image on it

if you do not maybe you can barrow one from a friend/family member/co-worker as long as it is the same version that is on your system

if you have (Windows XP Home Ed. sp2 ) then the cd will have to be that / if you have a cd with (Windows XP Home Ed. )you will have to slipstream (SP2 ) onto a disk that you create

this also applies to (Windows XP Professsional )

now if you do have the Windows XP cd with sp2 please follow these steps


performing a (sfc) system file checker

It is a scan that checks the core files & dlls of the (os) operating system and replaces them if they are corrupt or missing with the correct original version

  My HP G72 laptop recently shut down automatically and when I try to restart it, I get a black screen with blinking cursor in the top center of the screen. I have gone through various topics posted in this as well as other forums, but I am not sure how I need to proceed with this. I do not have a system recovery disc with me. I was able to go into the command prompt and when I did DISKPARTand list volume, I noticed that my C: drive has a Syatem Label but its size is only 200MB. My D: drive has no label but all my stuff that typically would be in the C drive is in the D drive. I have not created any other partitions in my computer. My E: drive has Recovery label but there is just one text file in there. I have backed up all my data and was thinking of re-installing the OS, but I wanted to see if there are any other alternatives which could address the issue. 
I have been running my laptop for several days continuously. I believe this could be a result of a virus attack for one reason that this happened as soon as I clicked on a link unintentionally.
Any help would be much appreciated.

I have a HP pavilion a6130n desktop that only displays a black screen with a blinking cursor in the upper left corner when you turn the machine on. Not sure if there have been any changes to the computer recently as it is not actually mine.

I can get into the bios fine but when i try to boot into safe mode i am unable to bring up the advanced boot option menu, i have tryed the F8 and F11 keys mulitple times with no luck. I have also tryed disconnecting the media drive on it because it says to do so on HP's website when doing a system restore. Right after the HP post screen (think thats what it is) it just goes black.

Any ideas why the black screen with cursor? or why i am not able to get into the advanced boot options?

Thanks in advance for any help

Hello, i have a Packard Bell Easynote TJ68 laptop. When i turn it on it comes up with a black screen with a blinking underscore in the top left corner of my screen. F8 does not work and neither does F12 or F2, the menus come up for the latter two but anything i do just puts me back at the black screen again. i cant log in and ctrl-alt-delete doesnt work either. I also dont have any CD's for the OS, the laptop didnt come with any CD's. the laptop is a refurbished one if thats helpful, please help!

A:Black screen with blinking underscore

This normally happens when you have a device plugged in that the computer tried to boot from, i would start by going into the bios and making sure the HDD is the first device to boot in the boot order menu. Just looked then and the key you use to load the bios is F2 ( hopefully that is right) it will tell you briefly when you start-up he machine in any case.

The menu your looking for is normally Boot with a sub menu along the lines of " Boot Order" or "Boot Priority".

Sorry i cant be more specific about that part..

Anyway, give that a go and let us know.

Hi there,

I just purchased a Dell Studio XPS 1640 with Vista Home Premium 64 bit software. I downloaded the latest itunes and quicktime to my computer. After installing, I play my m4v's and mp4's and I get this blinking black bar on the bottom of the player itself. It spans across the whole player (not the computer screen) and about 2 inches in height. Any ideas? Help!

Version downloaded: 64 bit version of itunes 8.1.1 (included quicktime 7.6)

Errors: There was a corrupted file error upon original startup of itunes 8.1.1 but I did not play any videos at the time. Once I noticed the blinking black bar on quicktime and itunes I immediately uninstalled and downloaded the itunes 64 bit version again. Still the issue occured, but no error upon start up like the previous install.

A:Quicktime Help! (Blinking black bar issue)

With more investigation, I found a solution, though I don't know what it means, but it stopped the blinking black bar!

What I did:

On QT player it self I went to:

The top menu tabs and clicked "edit" next to "file"
click "Preferences" then click "QuickTime Preferences"
click the "advanced" tab under QT preferences.
Halfway down on the advanced tab you'll see a section heading for "video"

You'll have options for Safe Mode or DirectX. You could enable safemode which got rid of it or you can disable Direct 3D video acceleration under DirectX.

Now why this worked I'm not sure, possibly someone out there could answer that for me? I have an ATI mobility Radeon HD 3670 vid card with 512 mb of ram. My vid card has the latest drivers.

Anyhow, maybe this could help someone else? Who knows! but that's what I found!

Hi everyone.

First time I've ever had a problem with my laptop in the 3.5 years that I've had it to this point that I have no idea how to fix.

I got overloaded with viruses/malware, but did remove all of it with MalwareBytes. Then, my computer froze and shut off later on, and became in the state that it is in right now.

When I try to boot normally, or click f8 to boot in safe mode, a black screen with a blinking underscore appears in the top left hand corner, and stays like that.

So, I ran f2 + f10, to get to the Setup Utility, and ran the Primary and Secondary Hard Disk Self Test, as well as the Memory Test - and all three tests came back with no errors found.

What else is there to do?

Thanks very much for any help!

Computer: DELL Inspiron 9400
OS: Windows Vista

So, my cousin gave me his laptop last night and said it wasn't working. He told me that it was a black screen and that was it. I gave it a look and started it up last night. The computer began to start and you saw the Dell splash screen, which read: DELL MPO61 Series, Bios Revision A09. In the upper right-hand corner there was the option to press F12, which gave you access to the Boot Menu, and F2, which gave you access to the Setup.

I thought it was something with the BIOS and that it needed a System Restore with a repair disk. I did research and was reading about everything from laptop screen issues to HDD failure to SATA failure. So, I did the following:

I entered F2 and changed the Boot Sequence to Internal HDD, which still gave me the black screen with the blinking cursor. The Boot Sequence was on CD/DVD.

I entered F12 and tried a one-time boot from the Internal HDD, which gave me the black screen with the blinking cursor again.

In F12, I also entered the Diagnostics and ran a PSA+ Pre-Boot System Assessment. The diagnostics checked everything from the system board to the hard drive to the cd-rom to the video card and lcd and memory. Everything passed the diagnostics tests. I'm a bit confused.

If I can't boot from the HDD, but the diagnostics is telling me that it ran a DST short test and that it passed, is the drive still good? Or is the drive toast?

Also, I tried F8 and logging into safe... Read more

I have been following different topics in this forum, I did try the "Verifier", but everything was fine.
I have no clue if this is graphic card, cable och screen problem, i have nothing to go on.

I may also add, this is happening randomly. But It could be worse when playing games!

I did try to remove and reinstall the drivers for my graphics card, also reinstalling the computer. But the problem is still there?

Well, basically what happened was I fell asleep and left my computer on.
When I woke up, it seemed to be kind of dead, it wouldn't turn off but it wouldn't do anything either. It looked like it wasn't connecting to the monitor. So I pull the plug, and try restarting it, it hits something similar to the problem before.

I do it again, it loads up this time. Everythings fine and dandy for a while, and then it locks up, first Mozilla Firefox freezes up, then a few other programs, then I hit the start button, it seems to work, for a second. Then it locks up showing only the skin of the start(No programs appeared or anything, only the black outlining of Vista). It seems the computer has frozen.

It won't turn off, so I plug pull. I turn it on. An HP Invent screen appears, and then the black screen with the blinking cursor. I can't do anything here, nothing, except turn the computer off normally.

I can, however, access the ESC, F10, and F11 options when I'm at the HP Invent screen.
So does is it a hardware problem? Or maybe I just did something to corrupt the system?

A:Black screen w/ blinking cursor

It may have been in "Hibernation" and was trying to copy the "In Use files" back to memory from the hard drive.
Now that you have pulled the plug several times Lord knows what has been done your OS and data.

You do have back ups of all your data, right?
Rebuild your machine to factory settings, install programs and restore your backups.
