Has this just occurred, or has this particular PC always done this?

If it's a recent occurrence, what have you recently changed on the PC -software? hardware?, settings? .........

Do you have another monitor that you could connect to your pc? it could be a problem with one of the pins in the monitor plug.

It could be the monitor itself, or as DaveSW said, try checking the cable that connects your monitor to the VGA card, maybe one of the pins are mis-aligned. try DaveSW's solution and put on a different working monitor. Give us a feedback on what happens to your problem...
