So im having an issue with ALL games, after about 15-20 minutes in the game goes black and the sound goes in and out like tiss tiss tiss type then It says DVI NO SIGNAL so im like well fuck, I know its not my Graphics card overheating or my CPU overheating, im having issues with my PSU and I don't want to jump to conclusions and say that it is my PSU.. Anyone know what could be the issue? I've reinstalled the driver and turned GPU to stock clocks
EDIT:
Okay so I have an update so after about 30 minutes in AC4 (Now it only happens on AC4) for a split second the monitor shows up and says "OUT OF RANGE" Then proceeds with the DVI no signal
Also to answer some questions I have tried stock clock and it still happens, also the GPU is still powered on and the whole PC sounds and looks like normal (Everything's powered on all the fans are spinning)
