I have a VGA monitor,whenever I use the monitor after some weeks the screen starts to blur and after some time the monitor goes dead.This has happened a couple of times.I have changed many monitors from some past years.Is this a CPU fault or something like that?

Completely aggree with Mehper, if you can't be bothered to reward those that help you how can you expect people to be bothered to help? – Joe Taylor Oct 27 '10 at 14:31

I would suspect the graphic card and/or the power supply (from the PC or the connection cable)
