Can't boot after running CCleaner

gregrocker said:

How many of the dozen steps I gave you have you completed?

Which bootable AV was run to check for infection?

Which is the Active partition which also determines whether repair will even work?

Post back a picture of PW disk drive map with listings.

Don't blame CCleaner when you haven't performed a single one of the Troubleshooting steps given.

I've tried the System Recovery Options (Startup Repair and System Restore) using the install disk otherwise I was going through the steps provided by Ztrucker because he was the first to respond. Over the past week I've had about three hours when I've been able to troubleshoot this. As far as blaming CCleaner, I can't state definitively that it was the proximate cause, but I can say that I ran it and then immediately restarted and the BSODs began. Everything I've said has been accurate.

As it stands now, I'm at the login screen and looking for advice on how to proceed. Your assistance is appreciated.

Click on the link for Troubleshooting Windows 7 Failure to Boot and start working through the steps. Report back as you go as other steps may be indicated.

Roger. I have Malwarebytes installed, so I'll log into the Admin account and reboot to Safe Mode and run a scan, thanks.

So when I logged in there was a message saying a System Restore had been completed. So the 20th or so try worked I guess.

I chose to Quarantine All.

sfc /scannow found corrupt files but was unable to fix some of them. CBS.log and sfcdetails.txt attached.

So how is performance after System Restore?

I've only been in Safe Mode using the Admin account, but everything seems fine. I restarted after quarantining the files from the MWB scan and it booted into Safe Mode without any issues.

So should I follow this to repair those files?

Extract Files from Windows 7 Installation DVD

And what is PW disk drive map?

It's in the tutorial. Partition Wizard steps.

A Repair Install may be best if files won't repair.
