Hey, recently I've been struggling with my pc, after I haven't been on my gaming computer for a while I started to install my updates over night and the next morning I got weird blue lines and my resolution got set to 800x600? Now I turn my pc on to a black screen without a cursor and I've tried unplugging all parts and still the same results, black screen. I'm using windows 7 gtx 1060 6gb and athlon x4 880k 8gb ram and not sure on power supply but it's about 550w gold +.
