Hi,
The bios look ok...
(You don't have onboard graphics...and disabled that option)
But it looks like the registry may be at fault....
You will have to completely remove your old installation of the driver.
The latest driver (for all) is
56.72Try loading up a generic vga driver (or go into safe mode) and then remove the nvidia driver...reboot and let XP find the new display adaptor....
(Try it manually if that fails)
i have that graphics card and it supports dx9 and agp 8X(so check your dx drivers also)
