I have PC with Q9650, 4GB memory, PNY nVidia 1.8GB videocard, Windows 7 Ultimate, ESET NOD32 188.8.131.52.
Everything was fine, but a few days ago I got system restart and it start restarting after 2-3 minutes each time and if I boot normally. Windows 7 Ultimate is restarting every time after a few minutes after I see desktop. I cleaned fan on precessor, and check a temperature with RealTemp and HWiNFO32 applets, but everytnings fine with cooling. Exept CPU temperature keep about 67 - 78 degrees of Celsius. After few cleaning it still restarting, but give me more times between restarts, sometime a from 5 min to a few hours after a few hours of a break.
I can't be sure if it software or hardware issues, and if this forum is a proper place, otherwise I'll move it to the hardware forum.
I don't want to reinstall Windows 7 and rather will try fix it (of course if a possible to find a solution).
Thank in advance and please help!
