I hate windows vista

[Dimitri13]

Umm..

Aero, Vista's default theme, is VERY graphic intensive. It takes up a LOT of ram when you use it. It has all that flashy stuff, like the menus, transparency, etc. It's really nice and all, but it will slow down even decent computers. For instance, the MMO I play on Vista, is very choppy and visually laggy, on a 2 year old computer with 4gb or ram. But on this computer (windows xp with 2gb of ram) the game runs fine.

So to fix your problem, turn of Aero (google it if you don't know how) or switch to like, windows xp theme.
