Please download and save the CheckSUR tool from http://support.microsoft.com/kb/947821
(you'll need to look in the details for Windows 7, downloading from the Microsoft Download Center)
Run it - The tool can take anywhere from 5 mins to a couple of hours to run (or 'Install') depending on how much it has to do, and may exit silently - it may appear to freeze for most of that time, but be patient.
The result is logged in the C:\Windows\Logs\CBS\CheckSUR.log file - and an archive …\checksur.persist.log file
Then zip the CheckSUR.log and upload it in your reply.
