Hi i have a problem here. I have tried to play a couple of games on my new graphics cars which is r9 380. But seems there is a problem with assassin's creed unity. Game runs smooth until certain points game freezes and then minimize itself to desktop. Tries to maximize it again no chance in task manager it shows as not responding. Sometimes the whole computer come to a red blank screen with weird sound and have to restart it. I want to know what's going on. Is it related to my PSU? I have got an XFX 550, and my GPU requires 6 & 6 power connectors and already got them. Tried another driver no chance. Is it relayed to the game itself ? Is there any chance I can determine the source of the problem??
