I requested that Evul post this question for me so that I didn't have to register an account. Seems that I still ended up having to make one anyway, so here's the answer to the questions you have asked ( and a few more that I'm surprised you have yet to ask ):
- AMD Turion 64 x2 @ 2.2 GHz
- Windows Vista Ultimate x64 (SP1)
- GeForce Go 7600, since I can play at 30+ frames unless I accidentally minimize, I do not need a new graphics card
- All drivers are up to date ( as of about two weeks ago )
- I do not have any viruses or spyware
- I defrag my computer weekly
- Doesn't matter how many times I re-install Guild Wars, it happens every time
- Video settings are set to max, this is not the problem because I can play the game comfortably at 30+ frames as long as the game does not get minimized, and even if I set them lower, I still have the same problem
- Guild Wars uses about 50% of the CPU when it is set to full screen
- I do not like window mode because the window is too small unless it is full screen
- If I make the window mode as big as the screen, the game still only gets five frames after I switch back to it from another application
- This problem only happens with Guild Wars, I do not have problems with any other game
Keep the questions coming ( or even a solution

)!
EDIT: I tried updating the video drivers to the ones posted in the link above ( since they were only four days old ), but the problem is not yet solved.
