Are your games folders in the program files on your C: drive? If, in safe mode, you can open the program files folder and see if the setup files are in the folder too. If they are, when you do the clean install you will still have a "Windows.old" folder on the C: drive, and the program files folder will be in there (Windows.old) too. IF the setup files are there, just reinstall the games. Otherwise, you will need to network that computer, somehow, and migrate the game files to it, for storage.
If none of this works for you, the Brink, I'm sure, will guide you where you need to go.
BTW, the games might be the cause of your troubles. Did you do the "uncheck drill" when you were installing them?
