Did you try doing the Windows repair in safe mode?
Also, a quite easy thing to do is the clean boot. Basiclly you make sure all background applications that aren't from Microsoft don't start and try a non Punkbuster enabled server.

I will await your results 🙂 Good luck.
I had trouble getting it into safemode, instructions for Windows 8 were a bit different. Once I got it there, I ran the repair and it gave the same message, stating that it was unable to repair all files. I'll get back to you tomorrow on trying a clean boot.
