umm make sure the power and video cable going to the monitor and from the copmuter is not loose
does your screen go black when not using the pc/ at the desktop?

You have a pretty old computer. I assume since you didn't state otherwise that you have an integrated Intel GMA graphics controller. It could be failing on you, normal hardware fail rates are around 8-10 years, which means it's getting to be about that time. If you wish, you can always order a very cheap PCI video card and see if that fixes the problem.

Based on the details you given, it's either the monitor or the video card. But it's certainly not RAM or Hard Drive. You could try the monitor on another PC to see if it does the same thing. You can also borrow a second monitor if you can and try it on your PC. This way you could rule out if it is the video card or monitor.

It could also simply be the VGA cable itself has internal broken wires, this would be especially true if your monitor blanks out if you wiggle the desk or something. I would try to find a new cable somewhere and try that before replacing major components.
