First see if it will boot and run in safe mode. If so, you likely have a driver issue.

If it will not run in safe mode, could be a hardware problem.

Add a comment to your question telling us what happens when you boot into safe mode.

Runs in safe mode but not in normal mode usually means a corrupt driver. Pinning the culprit down is a trial and error process. The most common one is the video driver.

Change to PCI VGA adapter in safe mode and see what happens.

Here's a link I found that may assist you in changing video adapter settings.

Disconnect all peripherals e.g. printers and USB devices. Remove add-in cards not required for bootup, only video is necessary. Disconnect power and signal cables from optical drives.

Try starting Windows with this minimal configuration and see what happens. At this point I suspect a hardware malfunction causing problems loading driver.

This could also be a thermal issue with the power supply or another part over heating. Try the safe mode idea that was suggested to rule out a driver issue and maybe try opening the side of the case with the box in a well ventilated area and see if it stays on a bit longer. Check all of the fans to make sure they are spinning too.

Good Luck,

The problem may be caused by over heating or faulty power supply fan,make sure that the cpu fan is working,also try cleaning the fan blades using pressure air

Boot to dos. See if the computer will stay running.

If it does not open the case and look at the fan on the cpu.

Dust build up will cause the fan not to draw the necessary air across the heatsink. Dust collected on the heatsink fins acts as a blanket and keeps heat in.

Use dry compressed air to **** the dust off. Use qtips if necessary.

Tech tip. **** the case out outside. You will not believe the amount of dust that will come out.

Good Luck Lee

Well guys, PC booted in safe mode with no problem. Opened case in well ventilated area and fans are spinning (on p.s. and cpu) and I cleaned the blades and **** dry also. Need more tips: You think maybe power supply is bad?

If it boots in Safe Mode and stays on then the issue is not
hardware. It is most likely a Spy/Adware problem, or a virus/
trojan, or a driver.

So many choices eh? In msconfig on the startup tab what is
running that should not be? Try disabling all un-needed ones
and trying again in normal mode. Either way you need to check
for malware. I use more than one app as none find everything. I
use Adaware and Spybot S&amp. Make sure to update the
definitions and have a copy of hijackthis on hand to check it's
log.

It is sad, but there are so many times I troubleshoot connectivity
issues or the like and now a days I can not troubleshoot
anything until I know the PC is clean of SPyware and Adware.
Once I trust it is clean then if the problem is still there I can
solve it. But, most the time the malware is the cause.

Good Luck,

razz

Well guys, this is what I did. Formatted my h.d., re-installed win98, and it did the same thing. I guess it must be a h.w. component in which I have no diagnostic tools to pinpoint what it may be. Maybe one or all of you could help me a little more.
