I dug farther, install the PCI-E card then reboot and go into the bios, navigate to advanced setting on video, change priority to PCIex first, then reboot and see if the new card works, then hopefully load the drivers when windows boots up.
heres some of the bios :
Advanced Chipset Features
Init Display First PCI Slot, Onboard, PCIEx (PCI Slot by default)
Video Memory Size 1 MB, 8 MB (8 MB by default)
DVMT Mode FIXED, DVMT (DVMT by default)
128 MB, 256 MB, MAX (128 MB by default)
