I switched gpu from r9 390 to 1070 yesterday and the computer isn't working with any of these gpus right now.
Once I start the pc it freeze after about 20 seconds, I tried to reset the bios but it still isn't working.
When the gpu isn't plugged it's working without any problem, what can cause the issue?
