Hey guys, I don't know if I've posted in the right place, but I was hoping someone here could please help me. I had to reinstall windows on my computer the other day, but since doing this, suddenly whenever I scroll a window it always stutters. It happens on every program, eg Word, Excel, IE, Photoshop, Google Earth... basically everything. It's really annoying because on programs like Excel it only updates one line at a time, and takes ages to use. It happens when scrolling both horizontally and vertically. Another thing is, if I reduce the size of the window I'm using so that it's as wide as the screen, but quite short (such as 5 rows on excel), it scrolls quickly and perfectly, no stuttering of any sort. I've tried different mouses, but nothing changes. Does anybody know what could be wrong? Any help would be great, thanks a lot.
