Allright so i just built my system and got it up and running last week. I downloaded the F.E.A.R. multiplayer from the companys web site and i installed and played it 2day. It was running really poorly no matter what i did, the mouse sensitivity was ridiculously high even when i adjusted it and the game was running choppy even at low resolutions (even though im running a BFG 7900gt OC!). All of a sudden my computer clicks and restarts w/no audio device!!!. I did a system restore and everything is fine. Did i do any damage to my computer? Did the CPU overheat?
