Did you use CCleaner to clean the registry? If so, I'd recommend NOT doing that - too many problems have been associated with registry cleaners.
One of the things mentioned in the BSOD screen is to wait and see if it happens again. This is because Windows has some error correcting mechanisms built in - and they (or the stuff that you've done) may have fixed it.
If it recurs, please zip up the contents of the C:\Windows\Mindump folder, and upload/attach the .zip file with your next post.
