Have you checked to see if the bios reports the cpu temp. Make sure fans are all running. You may want to check or reapply some thermal grease for the cpu. Also would take it down to minimal ram and try different sticks and slots. Possible ram issue. also if you have another vid card around try it. If you can try another OS like xp or 98 to try to recreate the issue. I know that maybe asking alot but could help rule out a hardware issue.
i am no lazier now than I was forty years ago, but that is because I reached the limit forty years ago. You can\'t go beyond possibility.
