CD/DVD not recognized BIOS wont boot from USB

Q: CD/DVD not recognized BIOS wont boot from USB

I have a Toshiba Satellite a85-s107 running Windows XP Pro, I have no floppy either

I cannot get the cd/dvd to be recognized even after reinstalling all of the drivers from the rescue cd using an external cd/dvd drive

If I could just get this dinosaur to boot to the external CD/DVD I'd be golden

My only choices in the bios are;

Any ideas??

I don't seem to understand your problem.

You say your Windows doesn't recognize the DVD drive, right? Why do you need to boot off the DVD drive, then?

I've built an 128gb Samsung (830 Series) SSD into my Acer RL70 Nettop. It was empty and when I tried to boot the nettop there was only the message "ERROR: No boot disk has been detected or the disk has failed". Then I connected the SSD to another computer and installed windows on it and it worked on that PC. When I put it pack into the Nettop i got the same error again. In the Bios, it shows the SSD correctly.

I also tried booting Windows or any recovery tool from a memory stick, but the error message appears before anyting else can load. The memory Stick is shown correctly in the bios and also it works with other computers.
I've tried the options IDE and AHCI as well as different booting priorities.

I don't know what else to try. If the memory stick can't boot, shouldn't it be a problem within the bios then?

Here are a few screens:

I have a Dell 700m running XP. Tonight I was streaming a movie online and took down my ad block program to view the video. A little while in firefox froze and I couldn't get it to close (even with ctrl, alt, del). Then I got the blue screen of death (i didn't write down the codes). I tried to restart the computer and keep getting the blue screen of death.

When I try to restart in recovery mode I get the blue screen saying to check for viruses on the computer computer. And to run CHKDSK/F to check for hard drive corruption, and then restart your computer.
Techinical information:
***STOP: 0X0000007B (0xF7BFE524, 0xC0000034, 0x00000000.0x00000000)

I tried to boot in safe mode and got the same message but with a slightly different code.
***STOP: 0X0000007B (0xf7b16528, 0xC0000034, 0x00000000.0x00000000)

When I tried to run the XP setup disk it stated "Setup did not find any hard disk drives installed on your computer"

Is there any way I can fix this without losing everything on my hard drive? What do I have to do to get it to recognize the hard drive again? (I read about putting the sata driver on my computer by putting it on a disk and adding it during the boot up process with F6 but I didn't know if this would delete the contents of my hard drive and also I don't know where to find the proper sata driver.) I know a bit about computers but not too much. I would greatly appreciate any help you can provide me. Thanks!

Hey there.

I'm trying to reformat my friends computer and i'm running into some serious problems.

Basically :

My friend has TONS of viruses and spyware (even got a call from provider threating to cut off the internet) and basically wants a reformat.

Now I have the XP CD in and go into the BIOS and change the boot setup to CDROM --> HDD (It won't lemme actually put my boot menu in my own order, just from "Basic" Which is HDD --> CDROM and "advance" which is CDROM --> HDD)

Now I did not get ANY message saying "hit any key to boot from CD"

As well, I hit F10 for Boot Menu and choose the CD ROM and still nothing happens and it continues to load from the HDD.

Now when i'm actually in XP, it's funny, I look at the CD ROM drive in My Computer, and even though the XP disk is there, it shows NOTHING on the disk, it doesn't read it (and it worked before), I try to populate the drive, and I get nothing.

I have reformatted this computer before and it was easy, now, the 2nd time, it seems impossible.

Any Tips?

Ok so, I got my hands on a free old PC. Its an Intel Celeron 328. It was running windows 98, but I took that off and began installing XP. While it was installing I hunted down some left over RAM chips that I had sitting around. It currently had one 64 mb chip and two open slots. I went out on a limb and filled both with 128mg chips... Except one was PC100 (same as the current one) and the other a PC133. (im guessing those are speeds)

Another piece to the problem might be that I turned the computer off to install the RAM while it was rebooting to finalize XP installation.

So, now the computer will turn on, and everything runs, but it wont even boot to the BIOS screen...its just black.

Did the faster RAM mess something up? Did not letting XP reboot mess something up? Or was it neither and the computer just died???

I have a custom built desktop and an asrock 970M Pro3 mobo. I have windows 10 and I noticed that today my computer was being really slow. I would open google chrome and when I would look something up it took at least 1 minute to load anything. I have an program called rainmeter and a few other addons for it that told me my cpu was at 100%. Long story short my cpu was running at 100% constantly even when (besides for windows programs) I only had skype open. I looked online and saw people were having the same problem. They said to update the bios and the original creator of the thread would always say something along the lines of "Thanks it worked my pc is back to normal!" So I downloaded an update for my motherboard bios and then after I started it my screen went black. Ive tried restarting the pc and dont know what to do. Please help!

Replaced my motherboard on a PB 150 with a new board and 233hzCPU. I have 64mg ram running win98 with a C:&D drive and a cdrom (G). The c& d HD have an exact copy of each other. It seems the system wont boot the operating system after the bios loads.Can I change the boot drive in the bios and see if the system loads from The D: drive? What else could be wrong??
Thanks in advance.

A:wont boot past bios.

You will have to determine yourself by going into the bios and checking itf it allows bootup from specific drives or not. You say you replaced the MB an CPU, did you reformant and reload the OS and Programs over again or simply place the old HDs into the new system? If you did not do a clean install, the old paramaters for the board and system are still listed in Windows and there is a conflict between what was and what is now seen on bootup. You state that C:\ and D:\ drives are exact copies of each other. If your saved information is indeed identical between the 2drives, I would use a Win98 boot disk, Fdisk, Format and reinstall your OS on the C:\ drive. When setup the way you want, simply copy over the data from the D:\ drive. You will still need to reinstall the Programs as they dont just copy from one drive to another. If the old system was still available, while in Safe Mode, you could have gone onto System>Device Manage Tab and near the bottom, remove everything under System then transfer the HD from the old to new. Windows would have then looked for the misssing system components and installed the new stuff. Just curious also about the comment that you have a C:\+D:\ HDs and G:\ Cd-rom. What happened the the E:\ and F:\ drives?

I have a dell XPS (one of the first versions from the early 2000's) running XP Pro . It has crashed alot recently and I was advised that it was probably a RAM issue. I ran 2 different RAM diagnostics (one Downloaded from microsoft one on the Dell Diag disk). Neither found a problem. I have had corrupted files and the windows repair wouldnt fix so I have had to do clean installs of windows.

Now the computer eont even load the Dell boot screen. All I get is the lights (three lights in middle above keyboard) come on the one with a letter A (I believe its a capslock light) flashes 5 times and then it shuts off. Never boots to even the Dell Bios screen.

I have a pretty big problem. My friend bumped my computer desk kinda hard (tripped on it) and it somehow reset the power to my computer. At the time, I was playing a pretty intensive game. The computer rebooted, and now the hard drive light is on constantly and the computer hangs at the menu screen before the BIOS. There's no power to my keyboard, so I cant press any function buttons to even try to access the boot menu. I've checked all the connections on everything - nothing fell out or got loose. I gave the computer about 10 minutes to cool down, but everything was running very cool to begin with.

If it's a hardware problem, I have recently (in the past week) installed a new slave hard drive and changed the thermal paste on my processor. And the RAM in my computer is kind of old, but the BIOS usually indicates bad RAM with a couple beeps. I'm perplexed. Any ideas? I can't afford a new computer.

heres the problem history:

-I wanted to install a PCI video card on this Socket 478 mobo and for some reason when booting with the new card ON the pc would freeze.

-So I checked the Bios Version and was an old one so I did an upgrade with the new version of the Bios. After flashing correctly as indicated in the mobo's manual I went in the CMOS settings and set it up to Optimal Settings and rebooted.

-the result: The system keeps asking me for the floopy disk with system to boot up and I noticed this message:

"CMOS/GPNV checksum Bad"

and I know most of the people would say try replacing the battery and I did and still getting the same problem so its not the battery.

when in a:/ I try to go to c: or e: and wouldnt recognize it. I also tried rebooting and going to the BIos again and tried to set the HD manually and its not there!

for the past few months, my computer doesn't want to boot. I tested my RAM, graphcs cards, blu-ray burner, and HD, the only thing I couldn't test were my psu, motherboard, and cpu. hopefully the problems lies somewhere in there. I did get a BSOD and looked at the dump and it pointed to my RAM, so I ran memtest overnight and it didnt find any problems so I'm wonder if my motherboard RAM slots are faulty? I also used a cooler masters psu calculator to see if my system was underpowered. I have 750w and it said I needed at min. of 786w, but it suggested the same psu that i was using. anyways, every once in awhile I can get my computer to boot if I remove and reinsert my hardware. Once my computer boots, I have no problems. The problem happens when I have to shutdown the computer. Once I shut it down, it wont boot. and suggestions?

If you are pushing the limits of your PS it could be causing your problems. Try running with one graphics card for a while and see if the problem goes away.

Hello all, first time poster although i often come to the boards to find solutions. You'll have to bare with me as I'm not that computer savvy (even though i think i am). Basically I have a Fujistu Esprimo Mobile v5505. I got fed up of Vista and thought i would install my old XP pro. I partitioned my drive and installed XP, i then formatted the drive that Vista was on. I came back and when i turned on my computer i got the NTLDR is missing error, now i would be able to deal with this but I cant even enter the bios to change boot options (which were set to flash, cd, HD). Before I fiddled with my laptop I had the options on the Fujitsu load up screen to enter BIOS/change boot options etc not anymore. I hope someone can shed some light on this matter.

remove the bios battery if you can get to it.
on my laptop it is located when i take off the hard drive cover on the bottom.
If yours is not check the other covers by unscrewing them.
The battery is a small circular battery like a watch battery.
Leave the bios battery, and notebook battery out, for about 5 minutes, and dont forget to remove the charger plug too.

First congrats on an excellent forum and helpful members. I have used the info this site loads of times before reading past threads and until now have never needed to post...

So here goes.
I have just installed a fresh (not new) hard drive in my system which is;
Fujitsu Siemens Esprimo P5600
AMD Athlon 64 3500+
2GB Ram
160GB SATA Hard drive
XP Pro SP3

The drive had XP already installed but was configured for an Athlon Dual Core system so i did a clean install. Deleted all partitions then created a new partition with NTFS file system (the slow method to check for disk errors)

Then i installed XP pro Sp2 all done from Fujitsu operating system recovery CD.
All went flawlessly and was working great.
Next day i went to boot and the splash screen came up with Fujitsu Siemens on it and the F2 or F12 options and the blue progress meter. The progress meter got to half way and then hung for about 2 mins and a black screen came up with a load of writing on and the message;

pxe-e61: media test failure, check cable
operating system not found

I did read a thread on techguy about this but it didnt solve my problem and my symptoms are quite different.

If when i see the splash screen i immediately press F2 to go to bios setup i can enter setup and view all settings. The HD is present and boot priority set to Hard drive. I then exit without saving or changing anything and it boots into windows and works fine.

Okay so I had this PC (acer aspire x1300) since 2010. It worked fine until one day my pc wouldnt boot into windows. I played around with it and did some troubleshooting, and found out that my SATA connectors on my motherboard werent working. Only way i got my computer up and running again is to use a USB to SATA adapter for my hard drive, and did a fresh install of windows 7. it was fine at first but my computer ran WAY slower than it usually does, so after a month i got really tired and wanted to find out how to fix the SATA ports on my motherboard. I thought updating my bios would do the trick, but it didnt and i had THOUGHT I did a bad flash. I tried literally EVERYTHING to get it to run, and the most i got from it was it powering on for a few seconds, no beeps, no video, no bios, and it would shut off. i gave up. I left the computer sitting in my storage room since 2011 (the cpu, ram, cpu fan, power box were all disconnected for these four years) and yesterday i decided to try to fix it again.

How to perform a Repair Installation of Windows? XP.

Two things are needed here, just a bit of old technology, an ink pen and a piece of paper to write down any special settings that might have to be changed back after the repair-installation is completed.

Please Note: Performing a "Repair Installation" in this manner should not delete any Personal Files, it should 'repair' the core of the installation but to be safe with your data you should follow the next two paragraphs.

You might have to remove the hard drive from this computer and install it in another computer as a slave drive and after it is able to be accessed by Windows on that computer you will have to manually backup all of your important data that you have to another media like CD-R's, DVD or external hard drive. Then when this is done return it to the original computer as a master drive on the primary IDE cable. and do the following:


The details that follow require an above-average understanding of the technical topics involved. If you do not understand the Registry material presented here, either find a technically knowledgeable friend or do not attempt to repair your system Registry yourself.

Hi Guys,
Hoping someone here can help me with some ideas for fixing my problem.

I have a Toshiba A70 notebook and the thing wont boot up and it has had various other issues like the power jack was broken. I ordered another motherboard and replaced the motherboard. I also have tested the locked screen and connections on another identical computer. I also tested the keypad and touchpad on another notebook and they all work fine.

I have also tested the hdd and optical drive and they work no problems on the other notebook.

In desperation I swapped out the processor for another one I had and same problems. The processor in there was a 3.0ghz processor and the one I swapped it for is a 1.8ghz.

So I turn the unit on and the light around the power button goes on and the fans and drive sound as though they are spinning up and three seconds later it goes quiet as normal. On a working computer this is when the Toshiba splash screen will come up but nothing is displayed. I tried using a torch to see if it was the backlight and I have confirmed that the lcd unit as a whole works. I also tried the vga adapter and an external monitor and same.

So if anyone is familiar with this issue or has any suggestions then they would be greatly appreciated.

Does it work if you put back the old processor?

The problems you are facing are probaly a result of whatever you changed. You could need to flash the bios to handle the new processor.

But it does sound like a LCD Backlight problem but you confirmed it's not.

Try checking the processor compatability.

I took out the new pair of RAM, and my PC bios gave me an error screen (detecting hardware) and said "overclock failed" and to reset the bios settings.

I didn't overclock the RAM or the processor so I don't understand why it said that.

I have an asus z97m-plus motherboard and 2x4gb corsair vengeance RAM, the new pair of RAM is also 2x4gb corsair vengeance, all of them are clocked at 1600mhz.
What I noticed though is that my RAM is clocked at 1333 mhz by default (I didnt change anything) which is weird because and it should be 1600mhz (?).

So I made a usb stick as I normally do.

Laptop detects it fine and can boot of it, laptop is old style of bios.

I tried to disable fast boot, disable secure boot, but still its bypassed.

Ironically a older usb stick I have with a 32bit windows on boots fine.

I noticed in the asus bios, on the drag drop boot order page the usb stick has [uefi] written next to it and isnt an option to boot it without [uefi] is this related to the problem?

The dvd drive has 2 boot devices one with uefi and one without.

Note I dont want to make a specialised uefi boot media, it has to work on old and uefi bios's.

Hi All,

PLEASE HELP!! I have a laptop containing important information thats not booting...

RAM: have removed ram and get CAPS key flashing constantly. replace RAM CAPS flashes once then stays off.

MOBO: CDROM drive flashes for a couple of seconds then goes out...

HD: HD access light flashes and goes out.

FAN: i can hear it!

The display shows nothing at all.. so i dont get the BIOS display or cant enter SETUP

The laptop fails to boot from a windows 2000 CD (win XP was the OS)

i used to hate people that kept posted please help messages... now i sympathize...

A:Inspiron 6000 wont boot due to BIOS problem??


Well it does sound like its a faulty Motherboard, if the info on the drive is important then either put the drive into another I6000 or use a 2.5 to 3.5 adaptor cable and read the drive contents on another machine.

Laptops by nature arent repairable by the common man and need specialist tools to determine cause of failure, that said if the unit is in warranty then ring Dell asap and get them to help you.

Pentium 4 1.7 GHz, 1024 mb [2*256, 1* 512], Compaq.

Found this machine without HD or memory.
its misbehaving-
Added an old HD and booted one time to XP but I couldn't pass the admion login screen without the password. With other HDs it had various problems. It said a few times an error with the IDE cable. I tried 4 different ones and kept getting the same error, so I doubt its that.

I removed the battery and reset the CMOS then replaced the battery. On startup the memory counts up and stops at 832 mb and a message says there is a problem with the memory and to try removing memory sticks to isolate it. That is 192 mb short of the total: Is that relevant?

Now it gives 2 beeps at startup, which if what I have read on these sites in correct means a memory error.
So I tried the different sticks separately but with all it gives a 2 beep code at startup.
I swapped the HD again, and maybe that is another separate problem, as an IDE DPS self test says it failed completion code 7. Now when I try to boot I get "NTLDR is missing, press any key to restart".

Also, when I go to BIOS, often the boot order has changed by itself. Also, one of the first times I went to BIOS it didn't even recognize a hard drive but then booted from it anyway!
I am not offered in the bios any Voltage analysis of the system to check the PSU.

My laptop is a Acer aspire 5738z running windows 7 home premium 64 bit and my problem is my laptop will not start. When I turn my laptop on it starts to run like normal: GPU fan starts, Disk drive kicks in, and the LED for the on button is working but nothing on the screen. I've tried too do alt + f10 for a restore, nothing happened. I've also tried to plug it into a monitor and my tv. Before this occurred it had been turned off during boot (don't ask why, I cannot answer that) and I preceded to take it apart(to fix the overheating issue due to acer not putting fan holes on the bottom of the laptop ((thanks Acer -.-)) and I didn't realise something was wrong with it until I reassembled it and tried to turn it on. So I'm not sure whether is corrupt BIOS, a hardware problem, or corrupt MBR (my own personal diagnosis, don't know whether it's right or not). Also I have tried turning the laptop off taking the battery out letting the motherboard discharge then pressing the power button for a minute, leaving it for a minute, putting the charger in then turning it on.

Thanks. =]

A:Laptop wont boot Black screen no BIOS

You may need to take it apart again and make sure everything is connected properly. Did you follow steps to keep yourself grounded while working inside the system?
As you add and remove hardware, follow these steps for ESD safety:Shut down and turn off your computer.
Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working. If you do not have an anti-static workbench, desk, or pad, you can use your computer tower/case by finding a metal hold in it, such as a drive bay.
Once these steps have been followed, it is safe to remove and replace components within your computer.

Hi nikar15 , 
Welcome to the Community Forums. 
Would you have the machine number? Check on the machine number from the sticker or check it from here ,just keep your serial number confidential.
Was it previously on Win8.1 ? Did you manage to create a recovery media ?
It would have to power drain the machine by removing the charger , battery and harddrive and to press and hold down the power for 12 seconds. 
Without the harddrive and battery , try going to the BIOS by FN + F2 or use the Novo button to start. If you manage to get the BIOS set up screen , go to the Exit Tab and load optimal defaults and save and exit. Turn off and put back the battery and harddrive and check.

Hi guys.

Been having BSODs almost every day for 2 months. Today the computer won't even boot to bios, even though I can hear the fans and maybe harddisk running.

Before the bootproblems i ran the following tests:

Memtest86: 7 passes with no errors
Memtest ( inside windows 7: Showed errors right away
CPU and GPU temperature measurement: Normal temps

The BSOD i got before the system stopped working completely are attached.

I would really appreciate it if someone took the time to help me, been trying to solve this problem for weeks on my own.

I think it might be the RAM, but it could also be the motherboard, cpu, harddrives etc right?

A:Lots of BSOD, now the computer wont even boot to BIOS!

If the system won't boot to the BIOS, you have a hardware problem. You'll have to fix the hardware problem BEFORE you can do anything else (all of our diagnostics rely on being able to see something in the screen).

Although I'm not a fan of the HCIDesign test, it tells us something that MemTest doesn't.
You'll have to test the individual RAM sticks one-by-one to see if you can isolate the problem stick(s).

What happens when you try to boot to the MemTest disk? Does the system work with that? If so, then there's probably not a problem with the video card. But, if it doesn't work with that, then it's time to look at the video card.
Double check all cables, then try another graphics card to see if that's the issue. If you don't have a graphics card to try with, then see about purchasing one from a place that will let you return it.

There are 34 memory dumps dated 15 Jan to 11 Mar 2011
13 different BSOD error codes
and 11 different causes blamed
This is most likely a hardware problem (as described above).

Once you get back in Windows, please do the following:
- Please update these drivers from the device manufacturer's website - or uninstall/remove them from your system. Reference links included below.
- DO NOT use Windows Update or the Update Drivers function of Device Manager.

Well, BIOS problems can be solved only by an Toshiba authorized service partner.
I assume the ROM module where the BIOS is stored, has not been flashed properly.
The Rom module can be flashed again using an special crisis disk.

Therefore I see just one real option for you: get in contact with the service guy to get it fixed.

I have an hp g72 and I encrypted my hard drive with truecrypt and I am unable to to anything with my computer now for the most part. In truecrypt setup i chose to not encrypt the startup files (I ask asked if i wanted to encrypt them and it said some computers need theses to be unencryted and some work fine without). If the HDD is plugged in, I cant do anything at all. I tried to get into bios and it recognizes that i press the key by saying something along the lines of "press f10 to enter bios" where it had said "press esc for options", then it goes to a black screen where I can not type. When I remove the HDD I can access bios and I changed the startup delay to 5 sec (to possibly give me more time to enter bios) and i changed boot order to boot from cd (my truecrypt recovery cd) but neither helped.

Any help is greatly appreciated.

A:Computer wont boot or access bios with HDD attached after encryption

It seems very odd that a hard drive would prevent the BIOS from operating in the way you mention. It does sound like an error has occurred with truecrypt and the boot loader section has been damaged.

I suggest you read through the truecrypt rescue instructions and see if you can restore the drive.

I am having problems with direct booting into Windows 8 installed into a VHDX file.
This is a four-partition UEFI boot on a GPT drive. EFI files are residing on a second partition of disk 0 (the ESP partition) in the EFI folder. The boot virtual disk is residing on the fourth partition of that disk 0.

I realized some days ago that my system was slow in responding. But not long i got the blue screen with white writings about 'crash dump things'. So i press the power button to switch off and on again. I enter windows normally. So fast forward to 3 days later. The system was responding very slow again so i used the power button again. On putting it on, the system will just stop with a blinking cursor at the left top corner(after the bios page). So i used the recovery cd that came wt it to try repair. The only option that worked was 'startup repair' and 'command prompt'. The 'system restore', 'image restore' from the menu did not respond to selection. So i used the startup repair option. On finishing, i restarted the system. But now, after the bios page, what i got was a blinking empty screen with the fan blowing simultaneously as if it wants to work normally. The f8 thing isn't responding at all. Please any solution?

Hello there,
It seems like you did not perform a clean installation of Windows and that's why your system is acting up. 
Follow the steps below to install a new copy of Windows:
1. To format your hard disk during Windows 7 installation you will need to start or boot your computer using the Windows 7 installation disc or USB flash drive. Insert your Windows 7 disc in your CD/DVD drive. Please note: will need to restart or turn on your system with the disc in the drive. 
2. After turning on your system with the CD in the drive go ahead and press any key when prompted during your computer post routine and then follow the instructions presented on screen. If you don’t see this go back to step 1 to setup your BIOS to boot from CD or USB flash drive depending on your installation media.
3. On the Install Windows page simply enter your preferences and click next.
4. Accept the Windows license agreement.
5. On the “Which type of installation do you want” page go ahead and choose the “Custom” option.
6. Select Drive options (advanced) on the “Where do you want to install Windows” page.
7.  Select the partition that you want to change, choose the formatting option you want to perform and then follow the instructions.
When allocating space choosing the default MB size for your drive is typically the best for most users since you want to take full advantage of all your disk... Read more

Its a packard bell laptop, and the system started to freeze for no reason. No viruses. Now, I can usually only move the mouse pointer-if it lets me start windows at all (xp). As of tonight, the system wouldnt let me even pass the startup screen, it kept asking for a non existent system password to continue! The system bios clock seems to reset itself too, so I believe the whole problem to be related to the cmos battery.

My main question is, how much should I roughly be expected to pay for a cmos battery and installation from a general pc repair store? The laptop is out of warranty, so I dont really want to be spending £30+ just for Packard to find and install one either. The reason I need someone else to do it is because this particular packard system has the most awkward setup, and therefore access to the battery is next to impossible..

as you can see from my (slightly blurry) photo-

there are only 3 panels on the back of the machine that you can remove- 1 hard drive, 2 ram, and 3 wifi card (I think!).. the cmos battery (the circle!) is to the right of one of the panels, under the casing. I have tried removing the entire casing, all screws and connections, and even from the front, trying to get to it by removing the keyboard, but it proved impossible to me, so Id rather get someone else to do it. No doubt the difficulty is on purpose so that you would always send it to packard for repair, and for a high price, bu... Read more

Hi, i bought a 6150b from a company auction. Everything worked perfect for the longest time. Then last week i went to go turn it on, and all it does is run the CPU fan for a couple seconds, flash the AC LED about 7 - 8 times, and while thats flashing the power and hard drive LEDís stay solidly lit. Then it completely turns off. This all lasts about 3 seconds at the most. Thatís what happens when on battery power.

When on AC power, the same thing happens, except it continues doing the cycle over and over again until I unplug it.

I think it might have something to do with the LCD monitor, since it does not even show a slight flicker at all. No color change like it would from when turned off to a black back lit screen when turning onÖ.simply nothing.

I opened her up (no warranty anyways) and checked all the connections for the keyboard, monitor, DVD drive etc....also reseated them as well, with no luck.

Pulled the both RAM modules and reseated them as well, nothing.

Pulled the battery as well, no change. Still cycles the same over and over again while on AC

There are no audible errors codes (real nice HP...), and im lost at this point.

Any and all suggestions are greatly appreciated.

A:Compaq Presario 6150b wont boot - no BIOS screen - powers on and off repeatedly

I think instead of just pulling and replacing the CMOS battery you might purchase a new one and install it. Proceed from there. If you get a screen and it's still has a problem try a new PSU. Jazz

I have an old PC (Compaq Presario Desktop 7470 ) that i purchased from a yard sale. I removed the old HD and replaced it with a quantum 30gb at Lct 20 HD that had Windows ME OS on it. I booted the pc and it booted fine except windows booted up in 16 bit color. I shut down and booted again. same thing. i shut down a third time and checked BIOS settings, then set them to default. Now BIOS doesn't recognize the HD or the CD-ROM drive. I have checked all connection, reset BIOS, removed the CMOS battery, I literally have tried everything I can think of to get things going on this old PC, but I am at the end of my rope. I will say that scandisk will recognize the HD and says it is OK. I have also taken the HD out and hooked it up to another PC and it boots up Windows ME just fine. I have also tried every jumper setting on the HD and Cd-rom to no avail and the only drive that shows up in BIOS is the 3.5 floppy drive which will boot up a Windows ME Boot Disk. I don't have a problem installing a fresh OS but want and need the PC to recognize the drives before i can do that correct?
I am ready to pull my hair out!! Can anyone please help me?!!!?

A:HD recognized by scandisk but HD not recognized by BIOS

probably the booting sequence is wrong due to the fact that you told the BIOS to load the preferred defaults. If you have a standard BIOS:

*go to advanced BIOS settings.... your going to see a big list of options .

<< check this picture for visual example>>
*take a look at the first , second and third boot device and change them to:

1- HDD - 0
2- HDD - 1
3- HDD - 2

Alternate them accordingly.

**probably the reason why your pc booted up at 16 bit the first time , may be
because you haven't installed the drivers for your video card yet.

I have tried to work forwards and backwards from barebones to complete and still nothing.

So my co worker asked me to look at her laptop its a toshiba tecra m2. The boot keeps hanging up on the system32 file agp440.sys . I went on the internet and found a windows xp pro disk to try and replace the system32 file using recovery. After a learning how to add SATA drivers to the windows xp boot I was able to detect the hard drive and just before windows setup screen comes up the computer blue screens with a 0x0000007B stop error... I read that the battery could cause this so i carefully took apart the computer and replaced it with no change. I put a windows 7 disk in to see if i could use the recovery console in it and suprisingly it booted no problem, i was able to use command prompt but with no idea what the problem is i have no idea what to do with it. If anyone has any ideas it would be appreciated. Thanks for reading the problem hope someone has an idea. any more info needed just ask


A:Windows wont boot hangs up on agp440.sys and wont complete boot off the disk :/

Info on 7B STOP errors..., scroll down to 7B in left column.

IMO, you have compounded the situation by using a "downloaded" version of Windows, since I suspect that such may contain embedded malware as part of the package.

Any number of things may have caused the initial hang, as you can see by reading the data at the Aumha website.

Synopsis: PSU died, replaced PSU with different model, system boots to bios successfully but does not recognize any devices in SATA ports, nor do those devices appear to be getting power. Now can't even get to BIOS, entire PC flicks on and off repeatedly as soon as I turn the PSU on regardless of whether I hit the power button on the front of the computer.

Original PSU that died: SeaSonic M12II 750 SS-750AM 750w PSU
CPU: Intel Core i5-3570K Ivy Bridge 3.4GHz
GPUs: ASUS 670 non-top version, SLI (2x)

A:PSU died, new PSU, bios wont recognize SATA devices, now wont turn on

I had a similar problem when I had an Antec PSU die on me. After I replaced it, my Biostar mobo's BIOS would no longer retain settings, and both my Pioneer DVD burners were completely dead. Not recognized in the BIOS, they would not acknowledge any discs inserted, nothing worked. I also started getting BSODs pointing to a corrupt BIOS. Replacing the burners didn't help. Putting the Pioneer burners in a new machine didn't work.

It turned out that the dying Antec PSU had wrecked the Biostar's BIOS chip and both Pioneer DVD burners. Replacing the BIOS chip was more expensive than buying a new motherboard, and reflashing the chip wasn't possible because the flash utility told me I already had the latest BIOS version. I ended up trashing the board and buying an ASRock board and Samsung burners.

If you get a new motherboard (or try another known-good working PC), and you connect your present SATA devices and they don't work, then the dying Seasonic may have burnt them out, too.

I am having trouble trying to figure out why this is happening to my system. I have four HDs connected to my machine. I have two of them connected to a Promise ATA100 PCI card, and the other two are connected to the Primary and Secondary IDE controller connections on my MB. When I boot up my system, all four drives are detected by BIOS. When I get into Windows XP Pro (SP2), only three of the drives show up under the My Computer screen. I have rebooted several times, and sometimes, the fourth drive does show up in WinXP. I have run chkdsk /f on the problem drive, and it comes back as clean.

Can anyone speculate as to why the HD is not detected correctly every time?

Thanks in advance.

Okay, here is the problem. I just bought a new system and want to move all my files from the old on to the new one. The old one will still be used so it cannot be formatted. I plug it in (jumper still set to master) and it boots from the IDE disk (winxp pro), now I don't want this, I want it to boot from the s-ata disk, on which my configured Windows XP pro is installed.

So I change the settings of the IDE disk to slave. It boots from the S-ATA disk (whoohoo) but fails to see it in windows/bios (DOH!). What am I doing wrong and what can fix it.

On an Asus Desktop M32AD. At boot, the F1, CPU fan error screen. I threw a new power supply and a gtx 950 in there. No problem. But I reconnected the hdd and DVD drive backwards in the 3/6GBS ports or whatever and my only hdd was showing up as removable media in the notification area. So I fixed that and now I get a CPU fan error at boot and my BIOS doesn't recognize the cpu fan even though it runs and everything is connected properly. I can just disable the CPU fan monitoring in the BIOS, but that's pretty weak. Any idea of what's going on here? Tons of threads, but nothing of value to me.This is a new computer, all new parts, putting the GPU and Power supply was easy, and there has been no issue with those and I've connected everything properly. I keep checking and trying to find out what the deal is. Really don't feel like sending my computer in. I'd buy another fan if any of you think that would work.

A:CPU Fan not recognized by BIOS.

I recently had a similar problem with a Compaq Desktop running Vista that had a noisy CPU fan. I found out that the computer required the 4-pin [conductor] fan, wouldn't work properly with a 3-pin fan although the fan did operate. Apparently it's all about the signals back to the motherboard about the fan being at the right speed, the CPU is properly cooled, etc.

Back to the table of knowledge again! Think I have two problems, maybe one is causing the other? Hard drive is not being recognized...on startup I get "inaccessible boot device". I go into bios and see there is nothing listed for a primary HD and also note that it also says "CMOS battery low" and "CMOS memory size wrong". The PC has been sitting in the attic for about three months since my son gave up on the HD issue but ol' computer impaired here thought I would give it a try. Would sitting with no power cause the battery to drain off?

MOBO is an ECS(?) K7S5A
HD is one that was left over from some other unit. My son said I had to change HD's so's not to loose his info on the original. HD is good cause I put it as slave in my PC and it worked fine. Not sure how much memory installed but the stick is in the DDR slot.

I know..kinda sporadic info but maybe can give someone as idea of whats wrong?

Hello all,

I had two machines. A dell and an Hp which I received from an office. The hp was more up to date. The dell had my software on it. I am fairly facile with hardware so I opened the case and tried to add the dell HD to a what appeared to be an extra bay below the Hp Hard drive.

I adjusted the jumpers to CS and poof, nothing. So, I took out (disconnected) the dell drive. Then I had the Hp drive up and running in windows internet ready etc...Well, so I figure time to try the other hard drive again.

No dice. It won't boot and seems only to want to recognize the older HD as Primary master. I tried switching the cable order -- nada. I tried changin the jumpers to master/slave appropriately. Nothing. So, I decided to just go back to barebones.

Well, now, it's not even recognizing the HP drive. "There is no boot drive present...please insert boot disk or drive..." It is not recognized in BIOS at all. Even with P/P OS turned off. If I disconnect the harddrive, I can get the windows repair CD to boot, but since it doesn't recognize the harddrive that's somewhat moot.

My next attempt will be to download maxtor's diagnostic test and see if it will find and test the drive. If not, maybe somehow it got screwed up. Otherwise I am out of options besides, replace that drive.

A:1TB Barracuda not recognized by BIOS

The typical solution is to update the BIOS if a new version is available. Until the BIOS can recognize the HDD, Windows cannot access it. The Seagate tools disc may have a software workaround. Have you tried running the Seatools application? It may work from within Windows, if not, you could boot from the CD.

And this post should likely be in the hard drive forum.

A:HDD is not recognized by Bios and Windows

Hello Raeion. Welcome to the forum.

When the hard drive is not recognized in the BIOS it means that either the drive is defective or there is a connectivity problem.

The first thing to double check is connectivity. This is how I would proceed:
(Please use proper static precautions!)
Disconnect the hard drive (I assume there is just one) - power and data cables.
Boot the machine and go into the BIOS settings > set SATA mode to AHCI and leave it there.
Reboot the machine, check the BIOS again. Should be in AHCI mode and you should see the DVD drive listed on it's port.
Shut down and carefully connect the hard drive again. Recheck the data cable connection to the motherboard.
Start up, go into BIOS settings and see if the hard drive is listed (when you start up, listen for the drive to spin up)
If not listed, shut down and try a different SATA port on the motherboard
If still not recognized, try a different data cable (the one on the DVD drive is known good).
Let us know what you find.

If you had this machine built for you then you may want to just take it back and get the technicians to fix the issue. Don't leave the store until you can see the drive recognized in BIOS.
If you were to damage something doing your own work you might void any warranty.

I am trying to upgrade a hard drive on a desktop pc (Advent T9306 - Motherboard: MS 7091 Ver:2). The problem is the drive is recognized in BIOS, but not when trying to perform a fresh install of either Windows 7, or XP. Both programmes tell me no HDD is detected.

So basically, the computer works no problem at all until I try to plug in one of my sata 1tb HDD's. One of them is Hitachi, the other is made by Samsung. Both 1tb, both sata. The Samsung is brand new out of the box.

These 1tb drives work in my other desktop pc no problem.

Now, when I plug one of my many old sata 40/60gb HDD's into the machine it recognizes them completely!?

Could this be that the computer does not recognize drives of this size as it is old? I have tried changing all settings in BIOS with no joy. I have even installed XP on one of the drives using another PC, then plugging it into the problem computer. It starts to load XP then restarts, and continues in a loop.

Please help as I have wasted my weekend off work on this!

I have Seagate Barracuda 7200.11 500 GB, it's maybe about 6 months old. It was working fine this morning, but after a power outage (behind surge protector) and a reboot, I got an error "hal.dll" is missing. So I went to work and looked it up and saw that IE 8 might be the culprit. So when I got home, I started to go through the process of recreating the boot.ini file that I thought was destroyed by IE 8.

Well come to look closer, I couldn't even find the drive in the BIOS. My secondary HDD was there, but not the one I was looking for. I tried in 3 other comps, and no dice, nothing shows up. The platters were spinning, but it's almost as if the firmware isn't responding or the driver for the drive, or something.

The data isn't so important that I'm willing to pay $1000's of dollars to get it back, but I would like to know if this is something anyone has experienced, a HDD to just die with no wawrning or anything. Also, if I get a HDD witht he same firmware etc, is it possible to just switch the electronic part, my pc board part, and possible have it work, just throwing out ideas.
