Hi everyone. Today while I was replacing my i5 4690k CPU fan in my Asus H81m-e , when I started it again it wouldn't boot with my Rx 560 ,then my rx580 ,the r9 270 and hd 6950 none of them boot , then I tried a low profile Nvidia one and it worked then tried gtx 750 also worked , the AMD's where working fine before but now they only work in other PC's. I've removed battery, reset CMOS/dram. And nothing seems to work. Anyone has any other solution?
