Sorry about the confusing title....Let me try to explain.

When I use the pin wheel to scroll down on anything, I get this lagged effect with a black bar that moves down. On my other computer it scrolls smooth without the lag and the black bar. It started doing this when I uninstalled Windows.

Anyone got any advice?

For anyone who thinks they are a comic: Yes, I reinstalled Windows. I'm not a moron.

Its a virus for sure. Your computer will die in 3....2....1....sadly this time there will be no respawn.....

You could also re-install windows...

Try updating your video drivers would be my first guess, but really, more information is needed.

Yeah, this happened to me when I was using a bad set of drivers, just update them and it should fix the problem.
Get new graphics drivers.
