Random lock ups and restarts while gaming
I am not a huge gamer. My main games include WoW, Half-life 2, and UT2004. My system is not fancy and is a few years old - Sempron 2600+, 6800XT, 1gig ram (512x2).
The problem I have is random restarts while playing games. For example, in WoW, The screen will lock up for a few seconds and the system will reboot. This happens fairly often, every few hours or so. Sometimes it can go days without it and sometimes it is every 20 minutes. This also happens in Unreal Tournament, and all the Half life games.
Now the strange part, I dualboot Windows Xp and Ubuntu. I can run WoW in WINE without the reboots. It still does the screen lock ups about as often, but instead of rebooting after a few seconds, it just pops back into action. I
I don't really know where to start with this. I replaced the powersupply with a nice Thermaltake 430W. I have also heard that it could be bad ram or a heat problem.
Any advice on what to check/try would be awesome. Thanks!
