When you boot to the recovery console you'll be asked two questions. First you'll be asked which windows installation you want - enter the number 1. Then you'll be asked for a password. Assuming there is none, just press ENTER. You'll be dropped at a command prompt. At that point type: chkdsk /r and press ENTER.
It will run two scans (one for file integrity, the second for disk integrity). When it's finished you'll be told it found and repaired one or more errors. Type "exit" and press enter. The system will reboot. To be honest, I don't expect this to fix your problems, but we need to get it out of the way before doing a repair install.
