I cant identify the problem..but I have reason to believe my computer is either overheating on my vid card or my pcu..problem is..both fans work..I have 2 fans on the case, one on vid and the pcu fan. Problem: When I play SOME games I start to hear a beep about 5 mins into it. And if I play too long while it beeps, my comp shuts down. But other games like...World of Warcraft are fine at full settings. At default most games I play pic the best settings and yet I still get this BEEP noise. Ive cleaned out my comp so there is lil to no dust..all the fans run..So im at a loss. Ive run a temp test, and everything is fine Help?
