After installing Win SP2 has anyone noticed their moniter acting strange. My moniter has little flashes down the left and right sides of the screen.

Have yall ever seen in a commercial or a video when it shows a computer screen and the big white bars are going down the screen. Well that's what mine is doing, but with out the annoying lines. It just kinda pulsates all the way down the left and right side. When it gets to the bottom it starts at the top again...

Does anyone know how to fix this?????

I tried unplugging everything and reconnecting the moniter.....

I first realized this after installing SP2
