Recently i sold my secondary gpu. It was leftover when i upgraded so i was using it to connect my second monitor to it and everything was fine for years. Since recently i sold it i just connected that secondary monitor to onboard graphics and problems started. Pc crashes sometimes after 5 minutes of usage sometimes at 1 hour etc. When it crashes everything gets stuck on both monitors, not even blue screen, just the stuff i was doing stuck as still images. Sound also gets stuck at one note which was playing at the moment of crash and keeps screaming that note. Any ideas whats the issue here?
