But this is weird. when the screen goes out of sync, the sound of whatever i'm doing will repeat itself on an endless loop, pc will stop doing anything, even if i press the caps lock button on my keyboard, it won't turn on\off. could the GPU really f up my entire pc? if it was the gpu, wouldn't the screen tear, or produce artifacts? even if it did cause the out of sync thing, wouldn't just the image get f'd up, but the rest of the pc work fine? i dunno, everything is pointing at psu or mobo
