WEll, i'm still getting reboots... again, seems like in warcraft... not always when I play, but frequently. Lots of times i can get through several games w/ no problem... then all of a sudden, in the middle of one game, bam- reboot. I just had the mouse and keyboard symptom again... i.e. load windows and at the login screen, can't move mouse or type on keyboard... It's not locking up b/c it will eventually run the screen saver, but you can't get keyboard/mouse. Although this seems to be happening very infrequently. Maybe I'll try a 400W or 430W? Either way, I think I'm going to send back the mobo/proc/video and get new ones.

I am having that symptom too, explorer as well as infrequently word/excel, are all of a sudden getting "critical errors..." etc. and for the program to end. I did just do the XP service pack and explorer service pack, so it might be MS related?

Any more thoughts would be appreciated. Do you guys still think it's the power supply (causing reboots)? 55 C doesn't seem too high to me, but maybe it's a bad chip or mobo?

Is PNY memory Ok? THat's what they sell at best buy here in town. IT was PNY optima. It said CMTL (or something?) certified, meaning they tested it or something...? Could it be bad memory?
