Windows 8 installs wrong driver HELP!!!

Ok so I installed windows 8 I have 2 GeForce gts 250's in sli..everything was fine. then a few days go by the screen turned black and came back on with everything huge as if no driver was installed. a few moments go by and it goes black and comes back on like it was. So I check the device manager, no I have a gts 250 and a gt 9800..So there goes my SLI..I uninstalled and re installed that didn't work..I shut off all automatic install settings went into safe mode, uninstalled the drivers cleaned registry and tried a fresh install..nothing..so I decided to install the gts driver by itself, and that automatically installs the gt 9800 driver.. I ran that little program cpuid and the stats for the video cards are identical only the name is different..i want my SLI back!!!
Im hoping one of you gurus can save me here..
