Monitor trouble

[hccarter]

I need some help!  My monitor is only 3 years old.  When my monitor gets a little warm (after being off) it will distort the screen.  The top and bottom go black but the windows screen I am in is still visible in the middle.  Sometimes it locks up but other times I can still work-on the area I can see!  My son stuck two magnets up the screen weeks ago but only for a few seconds.  Could this be it? :-?

Yes, probably.
Magnets cause problems with computer screens.
Is this a CRT or LCD screen?

Have you tried degaussing the monitor (CRT)?  Usually there is one of those buttons on the front of the monitor that you can do that.

Do you have a way to try your monitor on another
computer,or another monitor on your computer?
