Hi all - My computer screen will suddenly start jumping up and down, making it very difficult to read any thing on the screen. It does it on line and also while I am using Word Perfect. If I "wait it out" (this is typically the time I am frantically searching your forums for advise) -it will stop. I am a total novice with the computer...sigh. Please help me...trying to read the screen while it is doing that makes me feel a little drunk...if this continues, I may just take it up (drinking, I mean). Thanks in advance for any and all help...
