how to install new graphic card

hello

for my old mac pro (2009 - 4.1) i ve bought some new ram and a new video (graphic card) asus nvidia geoforce gtx670

first step, i search the driver of the card, mac version and installed it.

second step :

i remove the old ati redon, and replaced it by the new one

no problem on mac, the new card appears on the system

but when i rebbot on pc version, screen remains old black.

i now switch again, remove new card, replace with old one and tried to install the driver for the new card. but window (xp) refuse because it ask the card to be connecter, witch i can't do because i don't have the two connection (wires) i would need to be inside the machine.

could you please help me (french or english) please !

thanks

Mac Pro, OS X Yosemite (10.10.3), window xp through bootcamp

Put the old GPU in the Mac. Boot into Windows and uninstall the driver for the old GPU and switch to a Generic VGA driver. Shutdown your Mac, put in new GPU, boot Windows and install Windows drivers for the new card.

You can also try booting in Windows Safe Mode with the new GPU and install/repair drivers for the new GPU.

Try F8 or Shift-F8 and when booting XP. Please also see https://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/ boot_failsafe.mspx?mfr=true .

.... thank again

we tried both

at first tryied F8 but never wanted to reboot in safe mode

then remove new GPU, replace old radeon, then uninstalled the radeon driver, put a vga mode. than removed the old GPU and replace with the new one... the screen remains black again now...
