Ok I'm having problems installing new vidcard(evga6800gt). I unistalled the drivers for my old ati 9700pro (ATI Control Panal, Display Driver, and Uninstaller) and booted in safe mode and ran driver cleaner, turned off comp, put in new card, now when i boot up it just stays at the mobo screen. Thats it, it doesnt post or anything. It does this with both cards too. Plz help
