Hi. I have a Radeon RX470 graphics card that is giving me problems. This morning I switched on my PC from cold and all was normal. Ten minutes later screen went dead. Rebooted... nothing, only black screen (monitor soon shut down to sleep mode). Graphics card cooling fans turning...that's all.
I removed the graphics card and connected the HDMI cable to the on-board connector and rebooted. All OK.
Reinserted graphics card... no output again.
Removed the card and rebooted with on-board graphics.
An hour later I reinserted the graphics card... working normally again. Crazy.
