So I got an rx 570 a year ago and it's worked fine all this time, 2 days ago I overclocked it up 15% and it ran fine for awhile and then the grass texture in fallout 4 turned into like flat pieces of concrete and when I went to close the game the whole entire pc reset, now sometimes while I play it ctd's with no error randomly after a random amount of time and if the screen falls asleep I get rainbow static sometimes. Did I kill my gpu
