Okay, so I have Win7, 12gb dd3 ram, icore7, ATI Radeon HD 4800 series gfx card, newest driver. Whenever I'm in the auction for about 5minutes or idle in game for 5minutes, my pc shuts completely off while running D3. I never had this problem before. I can play D3 for hours on end without a crash, only happens when the char is not moving it seems.

Any advice?
