I just changed my CMOS battery and now my computer screen is jumping all over the place, like the fine tuner is messed up! I wore a static wrap, rubber gloves and I turned off the computer. I even reset my date & Time, and checked my monitor cables to see if they were lose, but their OK. Any ideas on why my computer screen is jumping around? I even checked the battery to see if it was good, and it is! Please help!
