When I try to use sfc /scannow, I am given this message: "must be an administrator running a console session in order to use the sfc utility." I have no idea what that means or how to meet that requirement.

Administrator minas the "owner" of the machine and I am wondering what you have set in User Accounts in Control Panel see pic

Not sure what you mean mate there is nothing posted with your reply. Now if the scan come nothing then no need to but do the other scan - chkdsk in the same way.
You are doing well:)

I cannot figure out how to get the black screen onto this forum. It says, "Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log."

I managed to find a CBS folder, but there was nothing that matched \Logs\CBS\CBS.logs

Also scanned with "verifyonly," and the report said that there were integrity issues.

OK, I've found the Windows Explorer folder that should contain the CBS log. What do you want me to look for there? Nothing actually says, "CBS log." I narrowed the choices down to 18 July, and may have found what you need. Not sure.

Follow what I have in my pics.

Well then it sounds like the OS is out of whack then and I can only suggest you run the chkdsk by whatever means you can.

The cause of the CBS logs not being there can be due to a lot of things and in this oldish thread I it may give you some ides of what is involved and unfortunately I think a repair install or reinstall with an image . CBS Registry Errors

This is why I always back up the registry on all new installs so that I can go back and merge that initial registry back into the machine - that may have been an option but I am guessing you have not got a reg back up.
