Thank you Brink. I had trouble getting the elevated command prompt to change path to C:\Windows\System32 but it seems to have worked in the end. http://homepage.ntlworld.com/merlin.five/sfcdetails.txt
All looks ok doesn't it. I was only trying to see if there's anything corrupted causing my very occassional event ID 41 kernel power issue. It only seems to happen during games, where it freezes along with a loud buzzing. Happened in 2009 a few times during playing crysis along with a BSOD, and recently a couple of times in a driving game, no BSOD, but freeze, buzz, black screen, and reboots itself. I disabled my overclock and it seems to have cleared up, although this happened a few times before I ever overclocked, so I'm not convinced the overclock is the source of the problem.
