I would personally replace the drive as it isn't really trustworthy after all that. But if you want to try to continue repairing it then run the actual maker's extended scan from boot disk (for best results) until it comes back clean, same with Disk Check. Then be sure to keep it backed up if you get it installed, which may require doing the Clean Reinstall Windows 7.
I'd at least see if that will install. Remember that if you stick with the steps in the blue link you'll get and keep a perfect install for as long as you do.
