So i just finished building a computer yesterday and everything has been working fine. Today i wanted to get into the bios but was unable to. It was suggested to clear the cmos. I cleared the cmos and restarted my computer. Everything in my computer was on and running, but nothing showed up on the monitor. So i unhooked my GPU and restarted my computer and it worked fine. Now whenever my GPU is installed in the pc nothing shows up on the monitor.
