I have just put a TI4200 on a fresh xp install. Its ok in windows etc, but i tried playing Wolfenstein and after a variable amount of time the screen goes blank. Ive reinstalled it etc, but i have no idea why its doing it. there is no other componoentry near it, and it is warm to touch but not hot. I dont want to return it t the guy saying its no good when it is... so if anyone has any ideas much appreciated!!! thnx
