Anytime I had a problem running sfc it turned out my PC was badly infected. I think I even have a thread around here from the last time it happened (not that it would apply to you, my PC isn't a 64)

I use Advanced System Care right now. You can set the sfc to run from it on the next reboot  but while it is doing it's scan to fix all the little shit before the reboot, it does a brief scan of the disk to look for errors then does the actual sfc on reboot. It 'may' be worth checking out. They have a free version of it HERE.

In the meantime or otherwise, my first instinct would be to run Malwarebytes and my anti-virus just to be safe.

*edit...just looking around, the first thing I came across from MS on this with W7 64-bit says -

There is a very good chance that you are seeing the effects of a hijackware infection! - post is HERE

Also - If you can boot into safe mode, try running the sfc from there.

oye.......

Look in Event Viewer....what's the error say?

Can I take that to mean you see none?

If your machine is running fine, why are you running SFC?

Oh there's just information events only 1 warning on a dns timeout its hitting a site that is unavailable. oneupindustries.com

What's the issue?

Aero renders just fine.

BigDogBigFeet you are not alone with this. I noticed a week ago that I can only get to 7% and then I get the same error message as you do. I tried to run it because I suspected my system was a little wonky with all the GUI theming crap I had been doing. I just ended up deleting some of the suspected files and restoring some of the system 32 files I had backed up. My machine is running great with nothing found with various malware and virus scans but I still cannot do sfc. Even though I feel there is no need to do the scan it still concerns me a little that I am unable to do it. Cannot even in safe mode.

Diagnostic startup would not work for me when I tried it.

Hi JC!

okay thx Yrag.

You know what it related to, right?

Well I do remember MS had an emergency security update over the Holidays Framework too.

I'm thinking since the rapair tool can find no problems that just to be safe I can run a chkdsk over night its been 6 months since the last one.

last one what lol

last one.. last night they all just seem to blur together.

alright BigDogBigFeet, say 8 Hail Marys' and I'll see you at Mass on Sunday, and don't wait so long next time for a Confessional. Now go in peace. .....
