My PC frequently "jumps or flashes" on the monitor SCREEN, resulting in skipping down three lines, if for INSTANCE, I'm creating an email or working in Word.

Recently, I began "chatting" on-line and when the flash occurs, the CAPITAL letters "UCL" are automatically entered into my chat message and the message is sent, without my directing so. :-/

Another, possibly related problem is that periodically, a "Supervisor Password" WINDOW spontaneously appears. I do not know if the two things are related or not. Does anyone? Does anyone know whats up with this? Can anyone offer a "fix" for either or preferably both?

I'd appreciate the help, this is quite annoying and distracting when trying to get work done, especially in Word!

Thank You Much, in advance!
