Power shuts down while booting

When I try to bring up the machine, power dies after 2-3 minutes during boot. I've disconnected the HDD, same problem. Now, I've got it sitting showing just the BIOS settings, and it seems to be fine (but it has shut down while I was poking around the BIOS settings). Nothing's been changed in the BIOS, the problem started happening every once in a while about a month ago, now it happens all the time. As soon as I try to start the OS (XP) it'll die again. I've tried reloading XP, but I don't get past the hardware verification before the system shuts itself down. Any ideas?? Thanks!

Re: power shuts down while booting

I fixed one like this. Fan went, and it blew up the video card. I replaced the fan and video card and it works like charm.

Re: power shuts down while booting

John here, customer advocate at Dell headquarters. I would suggest performing a hardware diagnostic. Your system should have shipped with a Dimension Resource CD, and if you boot to this CD, you should be able to see the diagnostics menu. From there, you have the option of testing all hardware components. If it is a hardware problem (and it sounds like it is) then the diagnostics should come up with an error code on a specific piece of hardware, or during the testing phase, your system should power off. Take note of where it powers off in the diagnostics, as this will most likely by the point of failure.

Re: power shuts down while booting

Hi there. It might actually be a few things. Have you checked your cpu's Fan and Heatsink for good contact on the cpu ? Looks like overheating of the cpu, but it could also be the PSU that has instable voltages, or the ram chip(s) that is faultly. If it crashes just in the bios, i wouldn't say it would be the hard drive(s). Put your hand on the processor's metal heatsink under the fan to see how hot it gets. If it doesn't get hot.. it usually means the heat is not transfering itself to the heatsink, not doing it's job. It might be incorrectly seated on it, or just missing some thermal paste ? Have you tested your ram chips for good operation ? I know if it's really crashing fast, it's useless. If you have a few ram sticks, try operating the pc from just one of them, if it still crashes, try another one of the ones u got. I know it's a lot of information to handle, but there's quite a few steps to do to narrow it down! Hope that helps, cheebster.

Re: power shuts down while booting

Most likely, the PS is saving itself from thermal meltdown. 1.) verify that the PS cooling fan is spinning. If it is, continue to step 2. If not spinning or spinning slowly, open PS and thoroughly clean using compressed air outside. 2.) remove PS connectors to mainboard and re-insert them. Repeat this 3 times to "wipe" the contacts to clean metal.

My acer AX 1200 continually tries to start up and then shuts down. Is this the power supply?

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your "((MOTHERBOARD TO YOUR HARD DRIVE))" make sure they have a secure connection and are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error even something as small as a faulty electrical extension or fan lead can cause this problem

follow the troubleshooting procedure a computer needs all of the data and electrical current to travel through every device and to have an end to be able work properly

a motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail check all electrical extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working also it could be a dirty computer clean all of the dust from your computer you could use a vacuum cleaner but whatever you use make absolutely sure there is no moisture gets to anything in your computer

hope this helps

My shuttle boots up for half a second, then shuts down. I have removed, HDD, RAM etc, but makes no difference at all. Any ideas?

Replace your PSU then test all leads that are attached to your hard drive sounds like a faulty lead of some sorts then
try replacing all the leads that attach to your hard drive including electrical extensions + IDE,SATA and the ones that attach from your motherboard to hard drive
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty because a computer has to have an end to the circuit any fulty leads will lead to no boot up
good luck

I have a T3626 E-Machine when I try to turn it on it starts to boot-up then shuts off. I've tried it a dozen times with the same results. HELP!! I have tried to start in safe help. Went to F10 at...

Try this. Go into your setup screen ( F10 or DEL ). From here set up the system to boot from another device ( hopefully you have the original Windows disk or a bootable 3.5" Disk)
I would like you to change boot sequence and boot from one of these other devices ( hoping that you don't have an infection which jumps to your clean boot - to prevent this on bootable floppy, open the little door}..

System is not workin properly

You might try this. Shut down the computer, disconnect power cords, disconnect everything at the back of the computer, mouse, key board, etc. Open the case, ground yourself by touching an unpainted area of the case and remove the power connectors to ALL optic drives and floppy drive if you have one. (Of course do not disconnect the hdd.)
Reconnect mouse, keyboard, etc., and power cords to wall outlet.
See if it will post now. If it does I say you have a faulty power supply.
I was given a computer which was doa. It would not post, after I tried the above routine it posted then booted to windows.
I replaced the psu and now the computer works fine.
Hope this helps!

Dell Dim 8400 Issues

Hi Steve,
The problem that you are facing is most likely because of bad harddrive. As you have already replaced the RAM. To confim the same , run a diagnostics on the Hardrive. You can run the same in two ways .

Check if have the utilitu partision still left on the hardrive
1. Tap on the F12 key 5 - 6 times when you see the Dell splash screen , before windows starts to load.
2. Select Hardrive diagnostics or IDE diagnostics

If the above is no there , look for the dell Rescouce cd
1. Boot the system using the dell Resource Cd.
2. Select 32 bit diagnostics from the menu
3. Run a custom test on the hdd.

If the hardrive fails , replace the same, otherwise try swaping it connector cable with the optical cable.
