Repair from Disc CMD prompt...?

So some W7 file got corrupted the other day, my computer straight crashed on me, and I cannot start. The regular "repair my computer" does no good, not even from the install disc. (Don't want to reinstall unless absolutely necessary.)

I have tried chkdsk- pretty sure I specified the right drive (did both available just in case)- nothing. Attempting the sfc /scannow thing, including "offbootdir" and "offwindir" (googled it), not really sure I'm doing it right, but I think I am. It gives me various messages, effectively saying some corrupted files unable to fix.

Can anyone help me, point me in the right direction for what to do... anything?

Am I screwed?

    Corrupted files? Best to test the hard drive then to see if that could be starting to fail. Use the hard drive manufacturer's diagnostic software for DOS which loads from a bootable CD which you can make from a downloadable CD Image.

    The download links for CD images are here for all except WD hard drives:

    For CD image for testing WD hard drives, the link is here:

    You can create a bootable CD from any of those CD images using IMGBurn:

    When you've made the CD, boot your faulty PC from it.

    Also, mine is a kingston drive.
