Shoe, I don't have a fix for your 3D problem, but I can give you some advice that will make your life easier.
This reinstalling of Windows is a needless torture you're inflicting on yourself. Get yourself a copy of Macrium Reflect. They have a free version.
Use it to make a backup of your C drive. Schedule it to keep making incremental or differential backups. You will be able to use it to revert the computer to a working state, as if nothing had happened, in just a couple of minutes.
For example, I have my JRiver server booting from a SSD. Any time I make a change, like a Windows upgrade or an MC upgrade, or putting in a new version of madVR, I take a snapshot first. If I don't like the results of the change, the time it takes to revert to the snapshot is about 70 seconds. It's literally like nothing ever happened: the entire filesystem, registry, everything is back to the way it was before. You don't have to think about undoing what you did, or about any ill effects.
It's a lifesaver, so I highly recommend it.
Good luck...
