I dont know. I had the SAME EXACT story about a year ago. It wasnt that exact card, but it was the same process. And its a XP SP2, just like mrtricks. One was a Voodoo 3dfx card. One time it noticed, and then the next my computer went totally stupid. Like I was installing a foreign language. I have to agree with mrtricks on a problem like this. He isnt the only one who has that problem with Windows XP SP2
