Some days ago i bought a gtx1080 and installed it, worked perfectly for some days, but then it happened, the fans went crazy and the display of the monitor was a black screen, yet i could hear what i was playing. At that time i thought it was because of my processor an i5-3450, i changed the thermal paste and the CPU fan, and the porblem was solved, it was like that for 2 weeks, then yesterday started again, and i don't know why, the temperatures are ok, both GPU and CPU, and my old graphic card, a GTX 760, uses the same quantity of 500W as the 1080... i'm going to try reinstalling the drivers..... any help please?! it happens during benchmarks, playing, and even doing nothing, one time i went to pee and when i came back the fans of the GPU where crazy already
