Been trying to get my computer to run as best i can. been having problems with trying to play games and videos and have pretty much given up. the other day i decided to remove all video playing software (i.e winamp, windows media, power dvd etc), also had to remove my current graphic card drivers to install the latest off the website. i did reinstalled windows media but still cant play videos, updated graphics card succesfully but now whenever i use the wheel on the mouse to scroll up and down a page, it kind of jumps, its not like a smooth scrolling process, its like the page has to load the next part (its hard to explain). any ideas?
