Hello Jim,
This is proving to be a tricky one 
Run System File Checker (SFC) from the Recovery Console (Please note that it is sometimes necessary to run SFC 3 or 4 times for all repairable errors to be corrected)
- Boot your Windows 7 installation DVD
- When you see "Press any key to boot from CD or DVD", press Enter
- At the "Install Windows" screen, click on Repair your computer at lower left
- At the System Recovery Options screen, make note of the drive letter assigned to your boot drive (normally C:) and click Next
- At the Chose a Recovery Tool window, click on Command Prompt. You will be sitting at X:\Sources directory
- Run SFC
- If you did not note the drive letter of your boot disk, you can enter bcdedit and look at the osdevice line to see what it is.
- For chkdsk, type chkdsk c: /r and press Enter (use the letter from above if not C:).
- For sfc, type sfc /scannow /offbootdir=c:\ /offwindir=c:\windows and press Enter (use the letter from above)
Let SFC run to completion undisturbed.
When SFC has completed, navigate to C:\Windows\Logs\CBS folder. You'll see CBS.log file.
