since the problem is probably either with the monitor or the video output, having 2 of each would help troubleshoot:

if you have a second monitor somewhere, see if you can connect it to your PC and get an image. Of course, make sure your monitors are set to receive the proper input (Digital/DVI vs. Analog/VGA).

If you are using a video card and your motherboard has onboard video, try connecting the monitor to that to see if the video card is the problem.

it's too early to fault the CPU for being the culprit. you're having a video issue, so first we gotta rule out the video card and monitor.

The monitor will not get a signal if the power supply or motherboard has a problem. If you do not get the normal single beep when powering on, then the power supply or motherboard is most likely at fault. More often it's the power supply.

Don't be misled because you see 'some' signs of power. The power supply has to supply several voltages, and a single one out of tolerance or missing can cause your symptoms.
