Help with TI4XXX v'cards

KENTON1

I have come into a pair of TI4XXX v'cards that I are broken an I believe salvageable. First is a eVGA TI4600 that shows a checkerboard pattern that is hardly readable. I got this in a system that was traded in locally. Second card is pulled from my neighbors Dell I believe it's a TI4200 OR a TI4600. )Don't know the maker). It shows good video until it's recognized by XP and it loads the appropriate drivers and forces a reboot that flashes a blue screen with lots of writing on it. The flash is very fast and in no way readable. Will a bios flash help either of these cards or are they ready for the trash can? Where can I get a bios file? ONCE and only one did the eVGA card show good video until it too got recognized. But it didn't flash with the blue screen. It just went to the bad pattern. ANY help is appreciated,,,I'll send them out if necessary.

Have you tried booting into safe mode to prevent the drivers from being loaded? If not, try that. I doubt that it's a bios problem. It sounds like a driver problem as in maybe a driver got corrupted or causing a conflict with something else. After you boot into safe mode use a tool to remove your present video card driver and then see if you can boot back into windows normally. Load the latest drivers and see if they work or have the same behavior. I don't remember the name of the tool that removes video card drivers but if you google it I'm sure it'll pop up. Hope this helps and resolves your probs.
