Here is the original bleeping computer thread: http://www.bleepingcomputer.com/forums/t/539786/unresolved-windowed-mode-application-stuttering/
This is a repost after it was found out that my problem was most likely to do with hardware.
There is a lot of information on both links, too much to put in one topic so please follow the links to see a detailed explanation of the problem and what stages I have tried to try and find a solution.
Extra information: I recently bought Stardock WindowsFX 5 and if I apply visual affects to windows, it makes it a lot worse when I move the windows, I can get a video of this if you need.
So, overall I would like help to find a way to stop this stuttering.
