Also true. Using the system restore option in XP is always a great fall back if you find further issues starting after doing this.

I personally only update my GPU driver on a regular basis and will not update others unless a specific problem occurs with it. Such as my creative sound driver.

PC's are relatively complex these days and if your system is stable and fast in other games and normal operations you can usually point to the game itself needing patches rather than looking at your own system.
