Windows Resource Protection could not start the repair service

I am desperate ...don't want to reinsall.

Internet Explorer will open, never resolve to a page, start to 'not responsd' and close

Control Panel | Programs and Features | Turn Windows Features on or off is empty

sfc /scannow produces the "Windows Resource Protection could not start the repair service" message

Windows Installer module service will not start

System Restore fails

chkdsk /r found errors and appears to have corrected

originally I just went to uninstall Avast anti virus, stop a few items for Start Up in msconfig, and install AVG ...the machine slowed down but internet explorer worked.  A complete AVG scan and Malwarebyets scan were completed successfully.  I tried Lask Know Good and System Restore.  Last Known did nothing and system restore claimed to fail.  Although it claimed to fail, I noticed that the AVG wasn't working and Avast showed up in the programs and features again.  So, seems like it partially restored.   Then IE would open and not stay opened.  I ran the chkdsk /r ... not the machine isn't slow, I have been able to establish a working IP address (good network connection), and IE open but would not display any page.

So, I manually cleaned up AVG and Avart from the registry, ran chkdsk /r again ...now, IE is back to not staying opened.  Also, the other issues still exist.

(1) Can't get Windows Features to show
(2) Cant' get IE to open

Any chance that there is anything else to try besides reinstall?

Is the chkdsk /r different from using the disc to repair the install?

Thanks so much in advance,
Dione
