My computer is constantly rebooting itself. I thought I had a software problem, and reinstalled windows. That didn't solve it so I reformatted my drive and reinstalled windows. The rebooting starting sparatically about a month ago and got worse as time went on.

My system:
Windows XP Home
Pentium 4, 1.5 Gig
256 Mb Ram
32 Mb Nvidia Video Card
20 Gb HDD
10 Gb Slave HDD
52 X CD ROM
CD Burner

This system is about 18 months old. So far I have changed the Hard Drive - did not help. I have changed the power supply (put in new Sparkle 350watt) - did not help. Used a different power supply in my office - did not help. Took out one of the RAM sticks, then the other - did not help. Cleaned it out completely - did not help. Checked all temps - were all good.

When I reinstalled windows XP, the computer would reboot part way through the install process. When I finally did get it installed, I have problems with all sorts of things (missed files on the install).

I now have XP installed, and have error messages (usually when installing programs - says a needed windows file is missing) and it still reboots occassionally.

I tried changing the BIOS settings - loaded in "fail-safe defaults" - did not help. Tried "optimized default settings" - did not help.

Any ideas?

When you are running Windows XP, you may have noticed that every so often (rarely) that Windows reboots without you asking it to. This tends to be caused by a Blue Screen error. If you want to see what this error is, you will have to check the error log list because Windows reboots too quickly for you to read what happened. Well with this tip you can disable the Auto-Reboot so you can finally read, and see the blue screen error.

Go to Start -> Control Panel -> System
Go to Advanced
Under the Startup and Recovery section, click Settings...
Under System Failure un-check "Automatically restart"

This will allow you to see the blue screen error that is causing the restarts and hopefully once you know what the problem is it can be solved.

It's frequently a driver issue

If you've already covered the power supply guess, which would be a good bet, how 'bout the cooling idea? Could something be getting to hot for you? If this was an AMD system that would be my geuss but I don't hear of it to often in P4s. Do you have plenty of case cooling? I've also heard tale of cheapo mobos using crappy methods to connect heatsinks to the northbridge. What kind of moatherboard do you have?
Here's a quick way to check for overheat. Take the side cover off your PC and point a household fan into it. Let it run for a while during your normal routine & see if that helps.

Thanks DVK01, but I think at this point I can rule out a software problem. It is happening, even with windows not installed. I will try the process to catch the error message though and see what it says.

Flyeater, the temps are all good. In fact the cover has been off the case for a while now and I have tried the fan trick - no luck.

Any more thoughts?
