Okay, so here are the symptoms: While in Windows, my computer will randomly lock up completely. That is, everything on the screen will freeze, numlock doesn't work, can't move the mouse cursor, ctrl+alt+del doesn't work. The only way for me to reboot is to hit the reset button. These lock ups occur about 1 to 8 hours after boot up. They don't seem to happen if I boot from CD (like, to use MemTest).
Here's what I've tried:
- Replaced the PSU (old one wasn't very good, sometimes wouldn't power on after being unplugged for a little while).
- Tested the memory with 10 passes of MemTest86 on c-1-2-2-3-0 (no errors).
- Checked the event viewer (no errors that coincide with lock ups).
- Ran thorough diagnostics on the HDD with Windows and the paging file on it (clean).
Haven't added any new hardware to the system (besides the PSU) recently except for a Linksys USB wireless adapter (and it's using the latest drivers). Lock ups occur at any time while using any application or none at all. Any suggestions?
Relevant system specs:
Windows 2000 Pro SP4
Radeon 9800 Pro
Athlon XP 2500+
1 GB DDR333
