Notebook in reboot loop

I can't find any SFC data in there?
CheckSUR is clear.
There are some interesting errors here...

Code:

The Event logs show some interesting errors - try applying this Fixit... https://support.microsoft.com/en-us/kb/2545227/
Note that the above events can also be caused by rootkit virus/worms.
There are also other errors which may indicate the presence of something that is attempting to modify your AV's settings.

Your HD may be on its way out - a CHKDSK log from November shows a bad sector, and recent entries suggest that this is spreading. You should back up your data to external media, and run a full CHKDSK /R

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)

Please also post the C:\Windows\windowsudpate.log file
