I bought an ASUS CUii 780 over a month and a half ago and it had been working fine up until tonight where it causes the top left corner of my screens to twitch and stretch and bad artifacting in games (2 monitors). HWMonitor reports my gpu getting a max voltage of 0.925V where as GPU Tweek shows it getting 1.025V max. Question is my gpu a lemon or is my psu crapping out? Its a Antec 750W HCG 2 years old.
