Error: Driver Is Stuck On An Infinate Loop

Ok guys, i DID my research on this and yes it states that the problem is in the driver. Im actually at work now and well, my client says he already downloaded the latest drivers and so far it still havent worked. im currently running tests on his vid card on XP Pro and so far everything seems fine. So, any solutions? coz i know the problem is not in the card itself, coz the guy wants the card replaced. and i already told him even if it gets replaced, it will cause thesme problem unless he gets a different type of video card.

Any suggestions from our dedicated viewers??
