My setup: MSI z99S Gaming 7 MB, Intel i7-5930k, msi geforce gtx 970 4g, 8GB DDR4 2400, Apevia 700w PSU. I just recently bought all this hardware probley within a month and for some reason when I try to play some games my computer screen will go black and a continuous freeze sound plays. The computer stays on and only way to turn it off is to reset it. I dont know if its a bad GPU or if my PSU isnt suppling enough power but i didnt think with my setup i would have any problems. Any help would be greatly appreciated.
