Solved Problems upon removal of Nvidia drivers.

I bought myself a Radeon HD 7770 a few months back to replace an old GeForce 9600GT. A few weeks after installing the AMD card, I was going through my programs cleaning out old files and decided to remove all the Nvidia stuff. I removed the drivers and stuff and upon reboot, my computer would no longer boot to the desktop. I ended up having to use system restore to get the computer working again...
Fast forward to yesterday. I upgraded from Windows 8 Pro with Media Center to Windows 8.1 Pro with Media Center, and I started experiencing the same problem listed here: "http://www.eightforums.com/general-support/33107-win-8-1-desktop-right-click-takes-15-seconds.html" I tried the same solution that was found and it did not work for me. My guess is it had something to do with the Nvidia driver software still being installed on my computer. So I again attempted to remove the drivers. At this point I couldn't even remove the Nvidia software as nothing happened when I pressed the uninstall button. I ended up having to reinsert the Nvidia card, and reinstall the drivers, in order to uninstall the drivers. After I restarted and reinstalled the AMD card, the computer, like before would no longer boot to the desktop. All I would get was a mouse pointer that would appear and disappear every couple of seconds and a Number lock button on the keyboard that would be turning on and off at the same interval. If I reinsert the Nvidia card the problem goes away, but obviously I don't want to keep the old card in my computer.

My question is: Why would the computer boot with the Nvidia card when the Nvidia drivers are uninstalled and yet not boot with the AMD card when the AMD drivers ARE installed?

I find it funny that right after I post this I manage to figure it out and fix the issue that I have been working on for hours. My hypothesis is that when I removed the Nvidia drivers, it removed critical files required for the AMD drivers. I ended up booting with the Geforce in my PCIe 16x slot and put the AMD in to my PCIe 8x slot, where it then booted successfully. Once in windows, I reinstalled the AMD drivers restarted and put AMD card back into the 16x slot and problem solved. Now time to fix those pesky DLL errors on boot, but that is for another thread if I don't manage to figure it out.
