I have been facing a computer problem where if my GPU comes under even a little bit of load it loses HDMI Signal, My monitors go blank and "Cable Not Connected " Message appears.
It boots up pretty fine and I am able to go under windows home screen . After the monitors go blank, my RGB Lights and fans are running normally but no display output.
I have had no such problems previously and my PC worked fine. For instance I just got FurMark the moment I ran the test my monitors went blank instantaneously.
I have reinstalled all Nvidia graphics drivers (DDU) and reinstalled them. Windows 11 is updated. Also I have not applied any OC or tweaks, its in default configuration.
I never had such a problem its happening suddenly please help.

Are you monitoring temperatures?

650W should be sufficient for that card, but I am not particularly informed on the quality of that unit.

Do you see anything in Event Viewer aside from Event 41?
Temps are normal I have to check event viewer tho otherwise all appears to be normal. My entire PC is working except the monitors. Unit quality has been fine PSU has been working since 2021 and also I don't live in an area that faces frequent power problems. What if some power surge or disruption might have damaged the PSU or the GPU
