Q: My computer broke down a while ago. I set it up again just recently and one time it actually booted up Windows XP and everything, and then the screen went black. I pressed a button on the monitor that had the number 1 by it and a box showed up in the bottom left corner of the screen saying... No Signal fH --.-kHz fV --.- Hz help please?
A: either a cable is not connected, you have it set to the wrong monitor or you set the resolution too high and the monitor doesnt support it.
