Sfc /scannow failed at 99%. Log details included. Kindly help. Thanks!

Hi there Sfc code experts,

- I ran sfc /scannow and it failed at the 99% mark. (unable to fix corrupt file as well)

Not sure if this helps, previously i was able to run Windows experience index (WEI) but not anymore since the sfc /scannow fails.
- The WEI gives an error and stops at - "could not measure processor performance"

Am not too sure if my RAM config is affecting anything.
Im running a total of 8G rams = (2x2GB Team Elite 1333) + (4GB kingston)
All rams at (PC3-10700)(667MHz)

Kindly need help here.
I cant make head or tails of the log file so hoping someone could give me a heads up,
so that i can find a remedy to proceed from here or better still give me a solution to it.

Awaiting help.
Thanks!!

Thanks for your reply ICit2lol,

The chkdsk said "0KB in bad sectors" which i assume is ok
but sfc/scannow still fails at 99% in safemode

Leftie mate the sfc is showing a lot of "cannot repair" stuff.
You could try this SFC /SCANNOW : Run in Command Prompt at Boot
I know it is a lot of fiddling around but may just get those files back in order.

Now before you do anything back up all of the data you need just in case you have to reinstall you can do this from an image for example if you have made one.
Otherwise just back up the data to something - I do an image on a regular basis to an external drive.

What ICit2lol said definitely. You might also want to take out that 4gig stick and see if that helps to at least finish the sfc/scannow. I tried a mismatched setup like that once on this machine (see spec.'s) with not so good results.

That RAM as indianacarnie says mate I was wondering earlier but then dropped the idea.

Personally I use matched stuff where I can - that is one dedicated stick or a a pair or quad number as the usually come from the same manufacturing batch and therefore more likely to be "in sync" with each other. Again as Indianacarnie said mixing brands also not such a good idea unless one is strapped for money or course.

Once again, thanks to ICit2lol & Indianacarnie

Will try it out when i get home from work.
And update results.

Cheers!

Hi there ICit2lol & Indianacarnie and everyone else out there.

Ive tried removing the single stick of 4GB ram leaving only 2*2GB team elite ram running
Tried running sfc/scannow in both safe and normal mode afew times to no avail.
Still fails at 99% and unable to fix corrupt files.

(Although sfc/scannow fails ive been using the com for afew months now without problems)

Now im left with the option of repairing the windows files.

Would like to ask ----> If i were to do a repair of windows files (NOT re-installation of windows), would it erase my (documents, pgms, jpegs, movies++) in my hdd?

or it would be safe to leave my (documents, pgms, jpegs, movies & stuffs) in Hdd while doing the repair?

Cheers

Before you do start a repair install - let's see if we can fix the existing one...

Please follow the Windows Update Posting Instructions and post the requested data
If the file is too large (8MB compressed), remove the older CBSPersist cab files until the final file is below the limit - you can always post them separately after zipping them. (the forum doesn't allow the upload of bare CAB files, for a number of reasons)
