I have installed a new GT640 and now I can't get by white screen/Apple logo

I have been running 10.8.2 with a GeoForce 9800GTX with no problems

I tried Graphics Enabler=no-PCIRootUID=0 & 1

I also have a third HDD that I did a clean install of ML 10.8.2 and the GT 640 worked but when I migrated apps from my other drive the boot problem appeared on the drive I did a clean install on

I ran -v and boot stopped at PCIconfiguration

Any help would be appreciated & Thanks

gt640 doesnt work for me I have a p67s-c43 from MSI I cant get past the apple logo while trying to install it
 
I have exactly the same problem with a GA-Z68A-D3H-B3 motherboard. I had a GTX-465 which worked perfectly but the GT 640 freezes when installed in its place. I can take the 640 out and put the 465 back in and the system works perfectly.

I used MultiBeast 5.2.1 to update everything and it still does not work.

Help !!!
 
Public confession of stupidity....

When I set Graphics Enabler to NO, everything began to work fine. (Just think how less stressful life would be if we would only learn to read...)
