This is what I would do not being a PC guru... I would try to do a system restore to before the update of the failed driver.
If that does not fix my issue, I would then proceed to uninstall all of the games in question, saving my progress of course, I would then proceed to do what suggested... uninstall of video and audio drivers, also the physx drivers, run Ccleaner after the restart (I always do it in safe mode to grab even more remnants), restart one more time and run Ccleaner yet again.
Then I would start to install drivers and then games to see if that fixes my issues.
I know, I know, way too much time and perhaps not solving the issue but since you can't play the games no matter what, might as well take the long road... unless of course you end up having to do a new clean windows install.
