Hello ! One day i turned on my computer and my GPU (r7 260x) wasn't sending signal on my monitor. Then i plugged my monitor to the motherboard to see if my GPU was getting detected but still i was getting no signal (i wasn't able to open bios too). Then i tried to open the computer without my GPU plugged in and it worked correctly. I tested the GPU on another computer and it had the same problem. Any idea of what i should try next ?
