Mel, you are a stinker, lol!!!
Every so often my screen goes black for about 2 seconds and I can't figure it out. I guess one day it will stay that way and I'll go shopping.
My DH was at the computer desk a few weeks ago and I heard a loud noise, (like something dropped) and then another noise. He didn't say a word. When I used the keyboard later, it only typed about half the letters. Mouse worked fine. The next day it was still misbehaving, so I called DH and he said something "might" have fallen on it.
I wasn't able to get to Radio Shack right away. Want to know something amazing? IT'S ALL BETTER NOW!!! I can't figure it out, cuz I didn't do anything special. Well, I DID replace the batteries (cordless), but that didn't fix it at the time. *cue spooky music*
