Question No video output after POST
After the system starts up, I see a 'no signal' message on my monitor and it shuts down. This occurs about nine times a day, but once everything boots correctly, everything functions properly without any crashes. I've reinserted the parts and connectors, checked for any short circuits. I've also uninstalled the drivers using DDU, reinstalled them, updated the BIOS, reset Windows, but the issue remains. I've installed the GPU on a friend's machine, and it works fine there, but in mine it causes the same problem. The issue disappears when I uninstall the drivers or enter safe mode. I'm unsure what else to try.
Is Windows 11 Pro legitimate? Is there a malware scan available for the system?
