Problem started 2 days ago playing f.e.a.r. 2 hours in, the game was running at the same fps and no artifacts or anything, but suddenly started freezing for a millisecond at every 1 second interval, stuttering the game play as well as the sound. I went to desktop immediately, waited 1 min, then restarted.
2nd case. This morning, turning my pc on, it stopped at "Boot CD/DVD" or something like that, left it for 5 min, was still there, restarted, and no problems.
3rd case. About 20 min ago, I was simply watching a video on youtube and the stuttering video/sound started again, again at every 1 second interval. I went to desktop, ctrl+atl+del to see my cpu at about 13%, nothing unusual, and the comp restarted on it's own...
Now I am clueless as to why this is happening, I have not made any driver changes for 2 weeks, nothing really I can precicily point my finger to, which is why I'm here asking for help to figure out the source of this problem.
This rig has non overclocked gpu, cpu at 3.2ghz, about 2 months old.
