I have an asus pundit-r. It has a pentum 4 processor. One day the computer wouldn't stay running and it would keep restarting. I thought it was a virus so I wiped the HD and installed windows again, didn't help.

So I then swapped out the hard drive, and the pc would still keep restarting. CPU temps were at 50 degree C, so I bought some ceramique paste, applied it (spread it around using a business card) and temps still go up to 50 degee and just sit there.

I don't know what else to do.

btw, safe mode works fine, it restarts as soon as it passes the windows xp loading screen and opens the desktop up.

Thanks in advance
 
Testing the RAM:
Download Memtest+ v2.01, unzip it, burn the ISO file to a CD, and then boot from it, just like you would do with the XP install CD. Let Memtest+ run for at least three hours on each stick of RAM separately. Go for a full 24 hours if you want to be completely sure that the RAM is not a problem. If you start seeing errors, than your RAM is defective
 
Ok i ran it for 11 hours, 37 pass 0 errors.

MB got to 50 degree, and processor was at 52 degree. restarted as soon as it passed the windows xp loading screen again.

Any help is appreciated.

Thanks
 
case is a asus pundit-r and the psu is a 200w. Its a friend's pc and he's had it for a few years now.
 
Try loading up Ubuntu or Knoppix Linux LiveCD and see if the system reboots then.

Also, see if you can use a different set of RAM in that system (Old set removed of course) and see if the starts still occur then.
 
put in different ram, same thing, kept restarting.

When I don't touch the pc for a while and its cold, it loads up the desktop and I can do stuff for about 30-60 seconds, then it restarts and will keep restarting right after the windows xp screen.

Could it be the heatsink on the cpu? could it be restarting as a safety cause things get to hot?
 
If it starts in safe mode, try uninstalling recently installed drivers and applications. Could be a bad driver or app.
On second thought, check the integrated video heatsink for secure fit and cooling.Do you have a discreet video card you can try and disable onboard video?
