I came home, booted up, and there is no image displayed on the monitor. I have that PC and another hooked up on a KVM switch. The other PC displays fine, so I know the monitor works. I unhooked the KVM switch and put the monitor directly on the problem PC. Still no image, so it also isn't the KVM switch.
The computer sounds like it is booting properly, but I get no image. What can I check and troubleshoot to figure out the problem?
