I have a EVGA 9800 GTX+ video card and lately it seems to run good until the screen starts to stutter. (If that's the word for it) The screen will have this shaky affect to it and I install the newest most updated driver and it goes away. The maybe a couple weeks later it starts to do it again. I install the same driver and it's fine. I run Windows 7 Pro if needed. Any help would be much appreciated. Thanks

Try to delete the old drivers and then install the latest ones. Use driversweeper or something like that.
