PC shuts off when running "Fix"

Thanks for your prompt input on my problem.  Did the repair and everything working as it should.  Ran a "Fix" and it discovered a collection of 56,442 junk files.  Wow! On a new build!  But only 2 registry errors.  Thanks for your help!

Everytime I run "Fix" my power goes off on my PC [Win 7 pro, 64bit]. Last few times it says my idenity is not protected.  Running AVG Free; new PC build: Asus A88X-Pro, OCZ 240Gb SSD, AMD TA10-5800K 3.8G Quad Core, 4Gbx2 (8Gb total) Ram.(I know there are memory problems, need to replace with authorized sticks - 2400 runs at 1600)
