How to troubleshoot a monitor display error after a system crash on an old PC with Windows 10? >
> I have an old PC with a Gigabyte GA-970a-DS3p motherboard and a Saphire Radeon R9200 GPU. I was using Blender when the system crashed with a grey screen and no audio. After restarting the PC, I could not see any bios or boot screen, only a monitor-generated error message saying "The current input timing is not supported by the monitor display. Please change your input timing to 1920x1080, 60Hz or any other monitor listed timing as per the monitor specifications." >
> I have tried different cables (DVIA-VGA and HDMI) and monitors, but none of them worked. The HDMI cable did not send any signal at all. The DVIA-VGA cable and the monitor worked fine when I connected them to my laptop. I have also checked the GPU and made sure it was properly seated, but that did not solve the problem. >
> My motherboard does not have a dedicated video out, so I cannot access the safe mode or bios settings. I suspect that the GPU might be faulty, but I want to avoid buying a new one if possible. Is there any way to diagnose and fix this issue? I have searched online for solutions, but nothing worked for me. I would appreciate any expert advice on this matter.
