Disabling the nVidia drivers probably won't help. Windows will then try to reinstall drivers for the video card on your next restart, and will more than likely find and reinstall the nVidia drivers. The only way to completely remove them is to uninstall them and use a program like Driver Sweeper to erase them entirely.
However, I would still hesitate to think the nVidia drivers are your actual problem. The current drivers have been out for quite a while and I don't think this is a typical problem.
Again, if all that you've installed is Windows + nVidia + a game, and you're having this problem it's probably one of two things:
1) Bad Windows install
2) Hardware Problem
If you don't have a bunch of stuff to backup, I'd reinstall windows from scratch all over again. If the problem persists, you likely have a hardware problem somewhere. In your instance, where it only manifests itself during Windows Boot-Up and nowhere else, it may be hard to determine what piece of hardware is having a problem.
Try reinstalling Windows first and see if that fixes your issue.
