Can't do both onboard video and PCI (not pcie) video?

[JEDI]

i have the amd690g mobo. it has radeon 1250 onboard video (dvi + dsub).

i have 3 monitors.

i installed a geforce 6200le pcie and the system (winXP) crashed while loading nvidia drivers.

i took out the geforce and installed radeon 7000 pci. the radeon 1250 drivers doesnt have drivers for the 7000?! so i d/l the 7000 drivers (dated 2006) and installed it. when i reboot, the system goes on a infinite reboot loop?

what's going on?!

No, you can't mix ATI and nVidia video drivers. To use a PCI card, you're supposed to completely remove your current driver, then load the PCI driver first, then load the PCI-E driver. And yes, I know your Radeon 1250 is onboard, but it uses a bus, and as new as it is, that's going to be the PCI-E bus.
