1. Safe Mode?
2. In some live CD/DVD/USB no install other OS like Linux Mint?
3. It does not look like an Aero issue.
4. Me too. I rarely clean off the old drivers. But if you must, here's a link about:

Hey there folks! I thought I could put up with it but I can't take it anymore, Windows Aero hasn't been functioning properly at all for the past 3 weeks or so and has some very strange visual bugs like this and has increasingly gotten stranger and more irritating.
Specs:
GTX 970 4GB
8GB of DDR3 RAM
AMD FX-8320 8 Core
MS Windows 8 home Premium 64-bit-SP1.
And yes, I have tried to reinstall display drivers multiple times which did nothing in particular, Tried running Malwarebytes, all the random stuff Google suggested and nothing. It should be noted that I recently upgraded to a 970 without uninstalling drivers first like a dummy, but I'm fairly certain this happened before the upgrade.
