Vista won't boot after motherboard swap

I replaced the defective motherboard in my Dell XPS 410 with what I thought was the exact same motherboard.  When I try to boot Vista it immediately bluescreened with the Stop 0x0000007B error.  I tried booting from the Vista CD and repairing the installation, but it was not successful.  The Recovery Console does seem to recognize that Vista is installed, and it does actually recognize the user accounts on the system.

I tried running bootrec.exe and initially it didn't recognize the Vista installation, but I found a way to rebuilt the BCD and that worked, but I'm still not able to get past the Stop 0x7b error.  

I've found a lot online that suggests that I should remove the hard drive controller driver and then Vista should start up and install the new driver, but I'm not sure how to do that.  At this point I can only get into the Recovery Console, though from there I can run command prompt and open regedit.

I would really like to keep the existing Vista installation if possible.  The old motherboard has swollen and leaking capacitors, but it was functioning at a basic level so I could possibly put it back in and uninstall the existing controller driver, but it seems that there should be a way to make this work without having to do that.  Any suggestions as to how to do that would be greatly appreciated...
