Hi. i have the msi r7770, and i OC'd with afterburner. i bumped it from 1000 mhz to 1025, then 1050. it ran furmark perfect on 1920x1080 burn-in test and the highest temp was 69c. then i bumped it straight to 1100, and it ran it fine, top temp at 69c. then when it closed out and was about to show me my pc specs, the window of the specs was kinda fuzzy. then it went black a few times. then came the blue screen. i had the fan speed of the gpu at 50% the whole time. i didnt touch anything other than core clock. any advice?
