High ms when in and out of instance


Hiya,
so basically like the subject says, i get really high ms whenever i teleport in and out of an instance, to the extent that i have to alt+f4 my client and get the game running again. sometimes i dont even get in/out of the instance, the loading screen just gets stuck.

Im using windows vista, no addons. Ive already delete wtf cache and interface, to no effect.

help!
