Ever since windows was re-installed when I 1st got my computer, the scrolling in any application or window has been jumpy and jerky, whether Im using the arrows or the scrolling wheel. I've been told that I may need to re-install my graphics driver. If this is the case could someone tell me how I go about doing this, If not any other advice would be much appreciated. Thanks

Do you have all Windows Updates?

Also check your settings: Right click My Computer then click Properties > Advanced > Performance > Settings > Adjust for best Appearance

If this doesn't work look in the Device Manager under Display Adapters (click +) for the ID of your Graphics Card: Start/Run/ devmgmt.msc
