Computer hard crashing while playing intense games
so recently my computer started to crash, noticed first with crysis 2 demo, I cant play more than 3 minutes without it hanging really hard with a solid color screen and buzzing through speakers. During the demo, my vid card makes all kinds of different squealing sounds, although it has always done this, in crysis 2 it changes pitch a lot depending on menu screen, in game, etc. When it finally locks up, I hear a little clicking sound for a second coming from my case. I've rolled back gpu drivers but still crashes, as well as during a long session of bfbc2 now. What gives?
