Ive put together a extreme budget build to last me until risen 3 comes out, and recently I've had issues with a black screen, after I'm done playing a game sometimes my screen will go black and ill have to restart my pc, i can still hear what is going on its just the screen is black.
My graphics card is a gtx 770 and my pus is a 700watt rose will glacier. I've been monitoring the temps and usage with msg afterburner and the temps never go above 73 c and usage is normally never above 60%. I've tried reseating the ram and the Gpu. this isn't really a huge issue i just wanted to make sure I'm not forgetting something and am accidentally damaging the card, thanks.
