Need Help! Can't Boot Up My Dell 8400 Computer

Q: Need Help! Can't Boot Up My Dell 8400 Computer

I just bought a used Dell Dimension 8400 Series Desktop Computer with Pentium 4 running Windows XP, and had it running for about a week. Then I shut it down and when I tried to reboot it up it gives me a message that says
'Type the system password and press <ENTER> Enter Password:' I don't know the password and I don't remember ever setting one up. I can't even get into setup.

Please Help. In desperate need.

Thank You for anyones input into this.

I want to fix my un-bootable WIN XP *OR* transfer *everything* from this 12 y.o. WIN XP (on a DELL 8400) to an appropriate WIN 8 version. But my XP won't open (missing or corrupt: Windows\system32\config\system). I lost my Setup CD ROM. I lost my password to open a repair function. I do have my original purchase paperwork to prove I am the rightful, original owner of my XP.

A:How to get my WIN XP on a DELL 8400 to boot

Is your intent to install Windows 8 on a 12 year old computer? If so, I suggest you rethink that idea.If you are planning on getting a new computer you can either install the old hard drive into the new computer or connect it using a USB docking device.The hard drive doesn't need to be boot-able when installed as a second hard drive. You should be able to read all the data, assuming you didn't encrypt the hard drive in the Dell.You can't transfer programs. Any that you have disk for and are compatible with Windows 8 will need to be installed again on the new platform. I assume you do NOT have any backup/ images? In the future you should get into the habit of performing regular backups of at least your personal files.

At that very moment the last thing i did was change the screen saver to none.. then it all froze.. This time when booting up it jus kept freezing i didnt think i was going to be able to get through but on pwoer up i heard a beep an got an error saying it was having trouble booting up at checkpoint[Ithr]

I havent really tried to fix it in any way thiniking i could mess it up more and not be able to get through at all .I looked at the Dell support site but i couldnt select what exactly is happening.. And Ive tried to run dell diagnostics before and i always got an error for that too so im kindve stuck.

A:Dell Dimension 8400 Boot up Error

This error can be anything from faulty USB devices that are plugged in during Boot to a failing motherboard to a bad RAM chip. Most common on that particular model of Dell is a failing motherboard as indicated by swollen (domed) capacitors on the motherboard..

I'd been getting RAM failure errors one my Dell Dimension 8400 so I took out one of the 512MB sticks of ram to see which stick was causing the problems, and it appeared to be the one I took out as I didn't get another error.

So I then put back the "bad" stick and left out the "good" stick to see if it worked, and I got the error again. So I then placed the "good" stick back in, leaving out the "bad" stick, and my computer doesn't boot up now.

All that happens now when I turn it on is a beeping sound about every 2 seconds and the fan speeds up to a very fast speed. No image appears on the screen. I've tried to turn it on 3 times now and have had to pull the power as I've got the same results each time.

Any help is much appreciated. Thank you.

A:Solved: Dell Dimension 8400 RAM and boot failure

Problem now solved. I realised that the little side clips/holders on the RAM slot were not sitting the side notches of the ram stick properly. Therefore, the sticks really was not installed at all. It was all just because I didn't fit them to the RAM slots properly.

Computer will not power up. Power light on the power on button is blinking amber. When I first plug in power cord, standby power light (AUX_PWR) comes on. Tried reseating main power connector, RAM, all PC cards. When I first press the power on button I do not get even a slight indication that the power supply kicked on then off. Need possibliities or solution!

A:Computer will not power up - Dell Dimension 8400

My first guess would be the pw supply however it cannot hurt to do some troubleshooting.
1 Open the case and pull the pw connectors from ALL drives; both hard disk and optical type drives.
2 Disconnect any usb type device; ie hub, scanner, printer, etc.
3 Pull out any add-in cards except the video card
4 Now attempt a pw ON. If you get a display, great. If not shutdown the system
5 Locate the pw switch leads on the motherboard. Remove the lead. Use a small screwdriver or other metal part to jump across the pins on the motherboard. If it still does not pw ON and post, clear cmos and repeat.

If still no post in the above config, you need to start swapping parts with known good units. Start with the pw supply since that is much easier to change out than the mb.

I was preparing my Dell Dimension 8400 for a clean installation of Windows XP Home Edition; I checked the Dell site for BIOS upgrades (as recommended) and downloaded an available upgrade. Problems began when I tried to change the boot sequence in order to boot from the cd.


On bootup, the Dell logo screen appears and goes to a 'dos-like' screen advising: Floppy diskette seek failure, strike F1 key to continue or F2 to run Setup Utility'.
Neither of these keys have any effect and the computer does not respond. I have the required disks and have tried every combination I can think of.

Can any one offer some help?

My old Dell Dimension 8400 P4 starts to boot but the screen goes black after the Dell Logo. The power was accidentally shut off on the power strip that the computer is connected to and after I turned the computer back on, this problem occured. I ran a computer diagnostic, I have tried to get to the screen to allow me to boot in safe mode by pushing F8 but when I do that I get a message that the keyboard has an error.

You need to contact Dell if your notebook is mis-behaving this way.

Because either its screwed up and asking for a Passwords, which is not something I've ever hear of. Or....

You need to ask the owner of the computer for the password.

WE are not allowed to discuss PASSWORDS problems because it usually means the computer is stolen. If not, contact Dell and they can verify ownership and help.

I have two almost identical (one of them has only 40Gb drive) Dell 8400 computers that worked very well together networked till yesterday. Both of them have same OS version including updates.
I had to do a PC restore on computer A and since then Computer B doesn't recognize computer A. I went through Network Wizard, made sure the computer names are unique and the workgroup name is identical on both machines. Computer B doesn't even show local shared directories anymore.
Computer A finds computer B without any problems.
BTW, Computer B works fine otherwise; I can access Internet, a network drive without any problems. I did hardware ping test and board test and they all pass.

dose any one know where i can buy a 1gb memory ram for dell dimension 8400.
it would be better if the site or the store is in uk

----thank you----

A:RAM for Dell Dimension 8400

This will give you useful information regarding your model and memory capabilities: 8400 Series

I would still open the case up and check the following:
The number of sticks currently fitted and how many slots are spare
The ratings of your current RAM Is it PC2-5300 or PC2-6400? PC2-6400 is faster.

If you already have 2x PC2-6400 memory sticks, then you can order another matched pair and increase your RAM on top of your current RAM.

If you have PC2-5300 RAM I would recommend you replace them with new PC2-6400 RAM.

You should order memory in pairs (matched pairs), as otherwise they can't function in dual channel mode and it restricts performance of them. According to Crucial you have 4 slots, so 2 are likely being used by 2x 512mb RAM sticks, leaving 2 left.

The best place I find to order computer stuff here in the UK is from I don't use anywhere else.

Link to the memory page for compatiable memory from Ebuyer. Its 2x 1GB matched pairs, of DDR2 PC2-6400 (DDR2 800) RAM.

Hello, new to the forums here and need help figuring out what to upgrade my Dell Dimension 8400 with.. I bought it Aug 2004 and the specs are:

XP 32 bit
Intel Pentium 4 CPU 3.00GHz (2 CPU's?) - does that mean 2 processors?
3 gigs of RAM
RADEON X300 series

Thats about all the info I can find atm... I am pretty sure it is using a 300watt Power supply...

Ok so like I said, I would like to do an upgrade so I can run high end video games. I know I might not be able to get the best FPS, but im sure anything would beat the graphics card I have right now right? lol.

So for a Power Supply, I was thinking this 500watt Dell PSU. Anyone know of a cheaper one maybe?

As for a graphics card... well this is where I am troubled. I read that some graphics cards will not fit in the Dell Dimension case. I am guessing this is true. If so, what PCI-E 16x cards will fit? I am ok with either ATI or NVidia.

As for cooling.. Well with the Dell Dimension, I see no 80 or 120mm fans besides the Power Supply fan. Would I need to fabricate an intake and outake for added airflow and cooling?

Is there anything else I need to take into consideration here?

Any help will be GREAT!! Plan on ordering the hardware from Newegg once we get this figured out. Thanks ahead of time for your help and if I left any information out, please ask and I will investigate asap.

Thanks again!

Mymachine runs fine most of the time.

However, at times it runs extremely slowly so that the mouse judders ans and sounds are broken.

Task manger shows 40-50% CPU usage but nothing in the proceses is using that (I have all user thing ticked).

I wonder if this is an over-heating problem as I once saw a fleeting boot-up message about a "previous fan error". I can hear a fan though! The room is cool.

So, would over-heating cause this? If so how can I tell if it is in fact this?

Over heating could cause your computer to slow down. I don't know that it would cause it to use compute cycles. Everest can tell your motherboard temps.

Hi all,

I'm sitting in the office scratching my head at this one! I have a Dell Dimension 8400 that was a bit messy (lots of viruses, malware and other nasties).

When these were all cleaned off I noticed that the USB drivers were not present (something the client had muttered about at the desk). I happily googled the appropriate Chipset driver, installed it and assumed that the issue would be resolved as per so many other cases. How wrong I was.

The peripherals in the USB slots are seen but no drivers can be found; indeed Windows was looking for a "USB" driver.

I'd like to get this one fixed before I head home tonight and was wondering if anyone had any solutions?

A:Best CPU upgrade for a Dell Dimension 8400 please?

It's not a matter of "the best" rather than a matter of what options the Dell proprietary BIOS version will support. Dell should be able to tell you that, as the model shipped with several different speed CPU's as a choice.

Problem is nothing in what you have shown above indicates what speed CPU was fitted to your model.

Most large PC makers restrict the "upgradeability" by BIOS limitation to only allow the PC to have the combinations that they know will work compatibly, and will work with the Power Supply. Otherwise call center staff can be run ragged trying to help with non approved and unknown mixes.

Generally I would never "expect" a Dell or HP etc to always be CPU upgradeable, it would only occur if there were choices at purchase time and the slower choice was opted for, it's quite possible that a faster CPU (but within the original range available) would work OK.

Remember that you can't just upgrade the motherboard either, as the Windows version is tied to it, requiring a new copy of Windows.

I need to replace the PSU in a Dell Dimensions 8400 because the fan is making a terrible loud noise.

I'm looking for some detailed specs for a Dell Dimension 8400 motherboard (my friend's system). Specifically, the system for no apparent reason could not be powered on.

The power supply checks out pretty decent, voltages are within specs. So I figure either the power switch or motherboard is bad.

Most of the generic instructions available for jumping motherboards refer to a two-pin momentary switch connection labeled PWR, or PWR_BTN. The problem is, on this board, there's a "front-panel connector" with around 30 or so pins, and a flat cable going to the front panel lights, power switch, etc. The power switch itself is fairly inaccessible, and I don't see any instructions provided showing how to remove it.

The cable can be easily removed from the motherboard. Where can I find out which of the 30 pins are the correct ones for starting the power-on sequence? Just my luck, the Dell Support Forum website has been down the last few days.

Thank you for any ideas!

IF Dell is stil using proprietary connections for the PSU's then your only option is with PC Power&Cooling. they make Dell compaitable PSU's. I havnt checked Dell's llately but I had heard that they were no longer using Proprietary connections, in which case you can use any retail PSU.

Dell should be able to tell you about the PSU and whether or not you can use an off the shelf one from any retailer.

Ok yesterday, I started my comp for it to go to a blue screen of death. I feel that I?m pretty good with comps, so anyway I restart after blue screen. I get to the windows xp logo and after that the screen just goes black and does nothing. So I ran a diag on hard drives and I have one hard drive from dell the 160 GB that come with the comp. That one passes the diag test and then I bought a WD 320 GB internal hard drive and when I diag that it gives me a fail response and code 7.
SO I?m pretty sure that this Trojan I have has corrupted a registry file during start up. FYI the operating system is installed on the 160 GB drive.

Boot into your Bios and look for a Hard Drive setting set that is set to AHCI mode, and change it to EIDE, Legacy or Compatibility Mode. If you can't find this setting then you need to slipstream your SATA drivers for your Motherboard into your XP disc using nLite.

My computer is making a lot of constant noise. The kind that happens when running a large program etc. I checked the task manager there are no open programs running but the CPU usage swings wildly from 10 to 70% I just went through a windows update and then there was an error message saying I needed a Dell driver check. Downloaded/installed said software and it did not find any problem. I would like to re-install XP I put in the CD restarted the computer got to the WINDOWS XP SETUP page and selected TO SET UP WINDOWS NOW it states that my hard drive is not there/not working. The computer runs OK a little slow and as I said above will not stop making the normal noise as through it has a lot of programs running. Any ideas as how to either make it stop making this noise or how to re-install windows XP (I have already backed up all my important files to CD's)


A:Help me debug my Dell Dimension 8400 XP home

Hard to help if you don't give a detailed description of the noise, or open the case and see if you can pin-point the source.

As how to reinstall WinXP, especially if you don't want to loose your apps and current configuration, you do a Repair Reinstall.

Repair Reinstall:Mount your original WinXP Setup CD in the drive and boot to it
When you are offered the 1st Repair option (bottom Status Bar) DO NOT use it, use Install
WinXP Setup should see you already have it installed, and this window will have a 2nd Repair option
The 2nd Repair option is the Repair Reinstall, and will reinstall WinXP by overwriting OS files with the original versions, but keeps your configuration and apps as they were
CAUTION - Repair Reinstall will require redoing ALL Win Updates (see NOTE to follow)

NOTE: When you have a large number of Win Updates when using Repair Reinstall, it is safer to use the [Custom] mode of updates and;When shown the list of required updates, use [Uncheck All] first
Then check [X] only 3 to 5 updates at a time
Install the 3 to 5 updates
Reboot your system, asked to or not
Then repeat this method until all updates have been done
This is better than having the [Express] mode of Win Updates fail (voice of experience)

Working on Dell Dimension 8400. Wouldn't boot into WinXP with message "missing windows\system32\config\system file. Safe mode and last good config didn't work. Went into recovery console and copied files from the repair folder and tried other tricks, and each time in safe mode system would load a little farther, before rebooting.

Decided to use the second repair option, booting with the WinXP CD that came with the system, but that option wasn't there. Googling this, apparently it does happen although I'm not sure what the explanation is and I tried a couple of suggestions to get it back without success.

According to owner nothing of value on hard drive so decided to reformat and reinstall. Setup copies files, gets to first reboot and then I get a can't find system drive message. In BIOS Hard drive (SATA) listed as first boot device and drive is recognized correctly. Tried different boot orders and new cable. Ran the full Dell diagnostics and everything passed.

And of course Dell warrantly ran out two days ago. Looking for suggestions before calling Dell, although I have to admit I just had a very positive repair experience with them when the hard drive on my laptop died.

A:Solved: Dell 8400 No Hard Drive

I was going to mark this solved. Actually the originally problem is solved. The SATA drive connector is somewhat touchy and wiggle the connector solved that for now. I've got thing installed but there were two question marks in Device Manager. The driver resource CD that came with the system for unknown reasons has 2K drivers instead of the XP ones that the system shipped with. Found the Ethernet driver on the Dell web site OK

There is both onboard sound and an Audigy2 sound card. I've disabled onboard in BIOS and have downloaded the supposedly correct drivers from Dell. They are self installing, but setup says it can't find the appropriate device and exists. Dell support keeps linking me to the same download and ignores what I tell them. I have tried numerous uninstalls/reboots.

Edit: Found driver on Creative site.

Can this power supply handle a 6800GT or 7800GTX. I would think so becuase the system can come with an ATI X800XT if you choose it from Dell.

I just want to make sure before I purchase a higher level video card.

DEll usually uses PSU's built by fortran so they are normally good power supplies. I believe that the 350 Watt PSU fals within the recommended guidelines for the 7800GT. if it doesnt you will have to get a new PSU, and since dell uses proprietary connections for PSU\Mobo you either have to get one from Dell or go to PC Power&cooling.

Hello All....HELP!!!

My 8 year old dell Dimension 8400 has been going swimmingly, until the other night a program I was using started to slow down, then the computer froze. After a reboot, it will show the splash screen, then says Loading PBR...Done!...then will go to a blinking cursor with a black screen...lastly to just a black screen.

I tried to boot into safe mode, as well as all the other boot options given when I hit F12 for setup, but everything just goes to the black screen. Is there a way I can get to a c: command prompt to do a chkdsk? I ran the boot diagnostics from the BIOS screen and it said the hard drive passed inspection. I reseated the ram, made sure all internal hard drive plugs were tight, etc.

It runs with Win XP and all the latest updates and service packs, Avast anti-virus, spywaredoctor, etc. I have 4gigs of patroit ram. About 9 months ago I changed power supply.

Are there any boot disk diagnostics I can download to check the hardware, software, etc?

I have installed Windows 8 on my older computer, Dell Dimension 8400. Everything worked except my sound drivers. I checked the website and there were 2 available downloads for sound drivers. I downloaded both. One said incorrect hardware, so I assumed that that wasn't right driver. I tried the other, and first it said Wrong OS, so I ran it in recommended compatibility, then it said Incorrect hardware. So both drivers must be incompatible? But when I had windows XP before, it worked perfectly. Not sure why it doesn't now. I also tried using the driver searcher thingy. It was searching for like an hour, and when I tried to stop it, it wouldn't close. I had to force close it, and it found nothing.

Does anyone know how to resolve this problem? If so, please help me!

The Antivirus program would pop up with error messages about infections and would say that the .exe file could not be found or run.I tried unchecking the LAN properties, but now I am no longer even able to open up IE at all. I installed Firefox from a clean computer, but now the infected one won't open Firefox either.I wanted to post a log, but I cannot access the Internet at all now on my infected computer.

Some of these fake antivirus programs are looking for specific programs to run and then terminating the program after launch.

Open My ComputerDouble click on the C: driveDouble click on the Program Files folderDouble click on the Malwarebytes' Anti-Malware folderRight click on mbam.exe (or just mbam), left click on copyLeft click on EDIT at the top, Left click on Paste. A file called "Copy of mbam.exe" (or "Copy of mbam) will be created.Right click on "Copy of mbam.exe" or "Copy of mbam", left click on RenameType in: blah.exeIf you do not see the ".exe" extension, please just type: blahHit the Enter keyDouble click on blah.exe or blah, wait a few seconds and Malwarebytes should open up.I figured this out one night when a friend's computer was infected and all the normal programs for killing running programs were being killed by the spy(mal)ware program.Let me know if this works or not for you.

My dad's Dell 8400 is having a series of issues. He posted a similar thread in the Hardware forum, but it's possible it might be more than hardware, so checking here to see if ya'll might have some suggestions (as I know this forum gets more visibility and he's getting anxious).
He turned on the computer last night to have it not booting up at all. It gave a series of 4 beeps followed by 2 beeps, and then wouldn't do anything after that. He tried multiple times, with one or two of them bring him to the BSD asking to boot in safe mode or system restore. He did try a system restore but that just caused it to beep at him again and then shut off.
Then this morning while I was on the phone with him it booted up normally, however he's got no internet connectivty with it. But he is able to access the other machines in the house that are on the internal network.

I'll be heading over there in about an hour or so, and will be there for a few hours. Any and all suggests or support would be greatly appreciated.
I don't have the technical specs handy, but if you need them let me know and I'll get them.
Right now I think I mostly need to know some decent diagnostics I can have him run.

I have a three year old Dell Dimension 8400 desktop running XP that I hate to restart or shutdown and reboot. It boots fine up through the command prompt for the password sign-on. Then it sits and sits and sits. After anywhere from 5 minutes to eight hours it will then continue cycling through the rest of the boot up to the Windows XP users screen. Occasionally I get ticked off, shut the machine down, disconnect all wires from the back of it, depress the start button to discharge all capacitance, then reassemble everything. Even then it is a 50/50 chance that it will go through the bootup cycle without hanging. Any ideas on what is causing this problem? It's been going on for all three years I've owned it.

Try to minimize programs that start with your computer using a startup manager:

Startup Control Panel
MZ Startup Manager
Startup Control Panel (Exe version for Vista)
Emsa Startup Manager
EM Startup Manager
WheresJames Startup Manager

Startup Programs Reference


Remove large files and folders from your desktop.

Run chkdsk /f on all drives to be sure there are no errors. Every time you shut the machine down with the switch, there is damage to the file system. Trying to get it to shutdown when there are no disk writes going on is like running between raindrops.

You can use BootVis to analyze and optimize the boot process.


Check all your connections inside the machine. If you get other, seemingly random errors, try testing memory.

MemScope (Floppy and CD images.)
Roadkil's RAM Test
Microsoft Memory Test (floppy or CD ISO image)

If you have enough memory sticks, you can test them by removing one at a time and see if the problem disappears.

If you are running Vista, tap F8 on boot and choose the memory diagnostic, or if you can boot up, go to Start > Search and type:

2. Is code 7 always fatal? I want to get some files from the old hard drive, can I add the sata to an existing computer with an IDE using an add in card, in efforts to try to get some important files?

Sometimes this computer will start, sometimes it wont

When it doesnt, the On button just flashes orange, when it should be solid green. Sometimes it will start up and get to the log on screen and then just shut down and flash orange. It works fine when it does turn on. Iv been through the dell help and support stuff and that doesnt help, this is my last option before i send it away somewhere. Anyone have any ideas???

As my Dell PC is out-of-warranty I'm having trouble identifying a suitable graphics card replacement. MOBO is a Dell 0U7077, bus clock 800MgH, Bios A09 dated 07/07/06. Running XP Pro with 3Gb of RAM. Currently have a Radeon X300 series PCI Express card. Any advice as to what I should buy would be greatly appreciated please. (Why is it Dell will not help unless I make a 'phone call to a paid-for help service and Radeon will only refer me to Dell for advice? Don't these companies want to sell me a new graphics card?)

A:Replacing graphics card in a Dell Dimension 8400 PC

Just about any PCI-E 16x graphics card would work, but you will need a new power supply too. And that will be a problem, because normal ATX PSUs will not fit in that computer, at least without bending and cutting the case.. Here's a decent power supply for you:
But wait... You won't need that if you don't want to upgrade. I would suggest upgrading if you like to game and are currently running a bit slow or ugly in your opinion. Another reason to upgrade is that you cannot find enough old and little power consuming card for your power supply to be enough for... Get the PSU I linked, and this graphics card:

What is the best card I can realistically hope to place in this machine without adding more power.

is an x1900 a reach?

The 375w psu has 30amps
I have the 305w psu with 22amps

The 1900 calls for 30amps

Ok, i have a dual boot system with Vista Premium and XP. The following issue ONLY occurs in Vista. XP is fine.

When I insert my headphones into the front panel of my dell dimension the sounds cuts from the speakers and enters into the headphones as normal. But when removing the headphones the sound should automatically transfer into the speakers, but this doesn't happen and i get no sound at all, not even i put my headphones back in.

I have rebooted and uninstalled/reinstalled the drivers to no avail.

Any ideas?

A:No Sound after using Dell Dimension 8400 front headphone jack

It is a simple mechanical problem. When you plug in the headphone jack, a spring leaf is moved breaking the circuit to the speakers. When you remove the headphone jack, the spring leaf is supposed to move back to the normal closed position. The metal used to construct your headphone jack was made of a metal too soft to spring back into position. You will have to open the computer case and bend the contacts back to the correct position. If you are electronics savvy you can replace the jack -- or you should ask Dell to replace your computer under warranty.

I'd appreciate some advice on a video card upgrade that will be compatible with an old Dell Dimension 8400.
I recently attempted to swap in an MSI GEFORCE GT720 1GB card, on the naive assumption that since it was a low power consumption PCI-E card it would just work - however all I get is a black screen (card works ok on another PC).

Any advice on a compatible video card  that's an improvement on the original one that the PC shipped with would be great.

I have a dell 8400 Dell with SATA HD. I decided to format the hard disk, and I received the error message : "Setup did not find any hard disk drives installed in your system". I read through the threads located in : .. Therefore, i was able to load the driver via floppy disk as suggested and succeeded to have my SATA detected and copied the xp files , but the problem is that once it reboots i got a black screen, means that i could not see any image (invite to complete the installation). the black screen flashes (comes and goes without having the time to see the screen).. What is the problem and what would be the solution .. thanks in advance..

Hey all,

First off I just want to mention that coming on here was my absolute LAST resort. I try very hard to not ask for help about problems that Google can answer but I'm running out of ideas here.

I'm running a 6 year old Dell Dimension 8400, Windows XP, 1 GB Ram, Intel 4 can't remember the processor speed exactly. A couple of months back my hard drive finally quit on me and I replaced that. Out of the blue, my keyboard and mouse stopped responding when Windows booted. Everything would load fine, Windows would do its normal startup routine, and my keyboard and mouse would respond properly for about 50 seconds after start up and then I would get nothing. The screen didn't freeze; programs were running but my keyboard and mouse just weren't responding.

Shortly after a few reboots, I started getting a Keyboard Failure message on BIOS start up. I looked things up and the only solution I really found was to reset the CMOS jumper. I did that. Now, I still get the Keyboard Failure notification but now when Windows starts to load, it immediately reboots and loops that forever. I disabled the reboot on failure option and instead of rebooting, I just get a very plain and generic 0x7B blue screen. I also removed the CMOS battery and tested it with a volt meter. Got about 3.something out of it so that doesn't appear to be the case either.

Now I'm stumped. I'm pretty sure it's hardware related. However I don't really want to think... Read more

Hello -
I hope Bev is still around as she has been so helpful to me in the past.  I have and 8400 that shut off while I was working.  I thought the power to the house went out...but it was just my computer.  Blinking amber light on the power button, no diagnostic lights in back.  Tried to start up, nothing.  Read posts here about it and tried removing CMOS for 10 minutes, removing PCI cards and disconnecting all power and connections from drives to MB (no change...still blinking light, nothing else), then did the jumping test from green to black (yes, I probably should have done that first...) and got nothing on that.  No fan, nothing.  
Can I definitely say it is the PSU?  If so, is the PSU from a 2400 interchangeable with this one?  If it isn't, are there particular brands I should look for or stay away from when purchasing a new PSU?

Thanks so much!

A:Dell 8400 blinking amber light won't start, no diagnostic lights

Blinking Amber means Bad Power Supply.
This particular model needs tin snips to cut a hole in the back for a regular power supply.  If you buy the startech model it will fit without requiring case modification.
Or you can buy one from an OEM vendor.

I have a discrepantcy.

I want to upgrade my dell power supply. Its currently a dell supplied 305w. Everyone says its alright to upgrade higher, even if it isnt a DELL part#, because a mobo will only takes what pwr it needs.
However, Dell Techs tell me that you CANNOT add a higher power supply to this system because it might damage the mobo.

So what I want is for anyone to post with info on them upgrading to off the shelf pwr splys and how it has worked or not worked with their DELL 8300 or 8400. Mine is a 8300, but info on a 4600 would be helpful as well. Let me know!!!

Thanxs guys in advance......

A:Current and Past Owners of Dell 8300-4600- or 8400 READ!!!!

I would bet lots of money that the dell people just say that because they want you to have to buy a dell replacement Power Supply. . . i would say ignore it and if it does by some microscopic chance fry the mobo, just get a new one. But make sure the newone (if you need one) is the same socket type (obviously).

I have a friend who has a Dell Dimension 8400 that is having major problems with his hard drive. He is unable to open any programs (all the exe files are missing).

I attempted last night to boot his computer from the CD ROM with the Windows XP system restore disk to re-install Windows XP on his computer.

During the boot process I hit F12 and it allowed me to choose the boot from CD ROM option. It then goes to a blue screen and at the bottom it shows some drivers and other programs it's loading. Then it comes to a screen that states, hit enter to re-install Windows XP, hit R to fix a problem with Windows XP and hit F3 to exit.

I tried both enter to re-install Windows and R ro fix a problem with Windows. When I do either it stated something to the effect that there was no hard drive installed on the computer? I then exit out, and it starts to boot from the hard drive and loads into Windows XP fine, but once again, he can't start any programs because it cannot find the file to use to load any given program.

Sounds like some sort of virus? The questions I have are, is there anything I can do to salvage his existing hard drive and re-install Windows XP? (he has already backed up everything from the hard drive). and question 2, can he just buy a new hard drive and use the Dell Windows XP restore/re-install CD?

Thanks in advance.

Title tells most of it: Dell 8400 w/Vista Business - screen flashes sparkling purple & green and crashes system. Occasionally I get vertical red and blue lines, but rarely

Dell has replaced the motherboard, video card, and hard drive. We've run diagnostics on the monitor and it appears ok.

I've spent in excess of 13 hours on the phone with Dell and Microsoft tech support. They've run (or had me run) every imaginable diagnostic. We've installed different video drivers (I have Radeon X300) to no avail.

It used to be occasional, but now I boot the system and it crashes withing minutes... sometimes as soon as Vista comes up. Sometimes I can boot in safe mode w/networking and it will stablilize but sometimes it crashes in safe mode too.

However, other times the purple/green starts flashing as soon as the boot starts (i.e., prior to Vista loading -- when the Dell logo comes up on the screen.

Has anyone had this problem? Needless to say I'm at my wits end with this.

So when the 8400 GS card is in my pc, then Windows simply wont boot up. I can go to F8 menu, and choose safe mode, but it freezes @ CLASSPNP.sys.

I can boot up @ onboard, and every gfx drivers are deleted (I did not use driversweeper, but i used CCleaner to remove the last .reg files), but it still wont boot up in Windows, when the 8400GS card is in...
Even though i disable the onboard function in BIOS, it still wont boot up with the 8400....

What should I do???

Hi, I have an unusual problem with a Dell Desktop. At the location where the computer is assigned (it's a work computer) the computer will not boot past the first Dell boot screen. it is on the screen where it says to Hit F2 for setup, F12 for boot options..etc.. There is a bar that fills up while booting, well this bar never fully fills up it just freezes on this screen.

If I take the computer to my location the computer boots and runs just fine. I know this other location has had power issues in the past and am thinking it is an issue with the power at the location but none of the other computers at the location are doing this. I have tried several other outlets at the location and same thing happens. Any ideas or has anybody seen anything like this before? thanks..

I have a Dell Dimension 2400 1.6ghz 1gb RAM with XP Pro on it for several years now. It has many programs installed on it. I purchased a faster used Dell Dimension 8400 3.6ghz hyperthreading 3gb RAM with XP Pro on it.

My question is simple. My Dimension 2400 has an IDE hard drive and the 8400 has SATA. Rather than spend days re-installing and tweaking all of the programs on the 8400 I tried the following. I used Acronis Easy Migrate 7 to Image the IDE hard drive to the SATA hard drive and installed it into the 8400. It would not boot, I tried a repair install, then while booting I get a blue screen stop Error 0x0000007B. What do I have to do to fix this so it will boot? What else is it looking for?

My computer is a Dell Inspiron 1520 with Windows Vista installed.
A short time ago, I pressed the Dell MediaDirect button by accident when the computer was off, and it started booting in a separate mode. I foolishly turned the power off because I had intended to boot normally, but thereafter, each time I turned the computer on, it tried to boot in Dell MediaDirect mode and promptly got a BSOD citing a Plug and Play error.

Following advice from the following two pages, I created a Dell MediaDirect Repair CD, and followed the instructions to repair.

Hi, I am having a problem booting to Window XP Home Edition sp1. I have a Dell 4600 Computer. It scenario went like this.

I would reboot again and It would be fine. Now this never happened when I logged on so I don't know what was up with that. I never upgraded to sp2 or 3. Maybe dumb but I make stationery for Outlook and Outlook express and build a few little web pages with applets and vbs scripts, so did not want the settings to mess with my applets on the upgrades.
