So, recently, I have noticed that I am frequently having graphics failure. This results in numerous games, old and new, creating vertical gray lines, the audio looping at a dramatic pace, making a spamming sound, then crashing. Sometimes this will restart my computer, and others it will just shut it off completely. I have had this GPU for a good few months now, and I have not had any problems until now. I have tried re-installing my drivers, uninstalling old ones from previous GPU's, e-installing the hardware, cleaning the dust from my computer, and re-applying thermal paste to my CPU in case it was my CPU overheating. I'm not sure what to do next, as I have tried everything I can think of. Anyone have any ideas?
