Blinking screen The screen on my computer suddenly starts blinking off and on in rapid succession. I will go for months and nothing will happen, then it all of a sudden starts. It will do it for a while, then stop and all is fine, then start again. If I do a clean up on the computer, it stops for a while. Sometimes when it is doing it, if I change to a different program or screen, it will stop. It is very intermitant. Any ideas ?????

Make sure the correct driver installed.
Check what is installed at this moment, do the following:

1. Go to Start -> Run and type: devmgmt.msc
2. Hit Enter/Return key.

A screen will pop up, are there items with a yellow questionmark icon? Is one of those your VGA adaptor? Then you need to install the correct drivers.

If you need help finding the drivers, tell me what brand/type/model your VGA card is.

I think the Screen has a problem not the computer... have the screen checked by a professional technician. Inside... he/she may find cold-solders (these are components that loses connection to the board) that causes the blinking or the rapid succession...
That's why patting the side of the screen sometimes gets better...
