Q: Won't boot after Boot Camp drivers are installed.

Background:

 

I have a late-2012 i7 27" iMac with a 3 TB Fusion drive and 32GB DRAM running OS X 10.10.4.  I have been successfully running windows in Boot Camp on this iMac for a couple of years.  As it happens, my model had the bad 3TB Fusion drive and about the time Apple announced the replacement program the hard drive began to fail (good timing :-)

 

After getting all of my Mac software running successfully on the replacement drive I decided to install Windows 7 64 bit again.  I used the Boot Camp Assistant to create the Windows partition and to install the drivers (BootCamp5.1.5621) on a USB drive.

 

The Windows 7 Home Premium 64 bit install proceeded without problems all the way to the point where the Boot Camp drivers app rebooted Windows.  Upon the reboot the startup failed.  I first tried "Starting Normally" but was taken back to the same point so I said to repair.  The repair process found no problems and offered to do a system restore.  I told it to do so. The boot proceeded without problems, but of course I had no Apple drivers so no internet, etc.  I then downloaded the drivers directly from Apple and installed.  Same problem.

 

My question...It has been so long since I first installed Windows on my iMac that I have no idea what version of the drivers I used.  Would moving to version 4 of the drivers possibly work or is there something really amiss in that version?
