I am at a total loss here...

Been following along some of Greg Hrutkay's videos on Youtube (Hrutkay Mods) as I have modded my Mac Pro 1,1 to a 2,1 with El Capitan. In it I have a Mac GeForce 7300 and a PC GeForce 660Ti with DVI Cable plugged into each and into seperate monitors.

In Mac OS, the machine boots, and smaller monitor connected to the Mac GeForce 7300 shows the preboot screen, loads the OS and once the OS loads, the second monitor attached to the 660Ti comes up and I can login to El Capitan with the second monitor off the 660Ti as my primary and it all works well.

I ran bootcamp and installed Windows 7 next. Only the 7300 showed video during the install which was fine as the 660 attached monitor stayed black. Once installed, I installed the bootcamp drivers and rebooted,s same monitor issue. Then, following along with the videos I watched, I uninstalled the drivers from the 7300 and told Windows via Local Policy to not install drivers for its Hardware ID (All in the video). I then rebooted the machine into Windows again and the only the smaller monitor was working still. IN Device manager, it now saw the 7300 under other devices as VGA Controller, no drivers installed. I then installed a couple different versions of NVDIA drivers for the 66oTi and each time the same thing....the drivers installed, I rebooted, Windows came back up and still only video on the smaller monitor using the default drivers. In Device Manager the 660Ti is listed as working properly, but no video is coming from it. Switching monitors around did nothing as then only the larger one would display off the default video drivers from the 7300 just like the smaller one had.

In these videos he does the exact same steps and both monitors are working. His is with Windows 10 but I dont know if that would make a difference as he states 7 would work to...



I see its possible, where am I going wrong?

Also, in Device Manager, I see no Monitors icon or listing for monitors...even with Advanced and Hidden turned on....not sure what is going on there either

So after a little digging and pulling the NVIDIA drivers off the Windows 7 install, I found that under Display adapters The "Standard VGA Graphics Adapter" has an error that "This Device cannot start (Error 10)" and that would be for the 660Ti Card.

The card works flawlessly in Mac OS and worked fine when installed on a WIndows PC, so I dont think its the card....wondering if something to do with Mac and Windows....
