xp restarts after 2 hours

[Guest]

I'm having a problem with Windows XP home edition. After running for about 2
hours, XP will go to the blue screen, dump the physical memory, and then
restart. At the blue screen, i get the error message "STOP: 0x0000007F
(0x00000000, 0x00000000, 0x00000000, 0x00000000)". From the times I've
monitored it, it gives the same error message every time. It just started
doing this a few days ago. I've ran Norton 2004 pro antivirus and Ad-Aware
SE pro multiple times on it, and found nothing. I did a repair to XP, and
then flatout reinstalled it, and I still get the same thing. I've installed
SP2 and all the critical/security updates that Windows Update has found
(including the four recent ones). I hadn't installed any new programs, or
updated any old ones in the days prior to these restarts (aside from virus
definitions for Norton). Any information or possible fixes for this would be
greatly appreciated.

It's usually a RAM issue - suggest you test it (www.memtest86.com).
