Hi Everyone.

I have a very wierd problem. Yesterday I have changed my PC's GPU from Sapphire Pule RX 580 GB to a Gainward GTX 285. The reason of the change, I just borrowed the AMD one.

So before the AMD I had the GTX 285 in it, and it was working plug and play. I inserted the AMD GPU booted up, uninstalled the NVIDIA drivers, installed the AMD drivers, changed the adapter properties to 144Hz and to 10bit , and it was working without issues.

Yesterday as I had to give back the AMD GPU, I have forgot to uninstall the AMD driver and just pluged in the GTX 285 GPU. And my system boots up, but not screen. Only a message on my monitor no HDMI signal.

I was trouble shooting it, changed, the HDMI cable, changed the HDMI 1 to HDMI 2 on the monitor. Changed the DVI -> HDMI convert, but nothing has changed. Same issue. I Have tried an old NVIDIA GT 630 gpu with mini HDMI port and the same issue.

My CPU is a Ryzen 5 1600AF with no integrated GPU, so I can't use that solution. As I have no signal, I can't go to safe mode either.

Please if you have any idea, help me out.

I agree with @helpstar But I would also try removing the cmos battery for 5-10 minutes then putting it back in. If this doesn’t work then try a different Drive in the pc and see if it displays, if so then it’s probably a driver issue
