Windows 10: SFC not working and neither is DISM

Hey, I'm new here.
Maybe I should start a new post, but let me just start here, as this thread is the closest to my problem that I can find.
I have a very old laptop, but despite the age it has worked relatively fine for my needs with just an HDD change. I bought this at the very end of Vista lifespan with an almost immediate Win7 upgrade offered. I then skipped Win 8 totally, but rolled a Win 10 when it came, and it has been working well. But you get the picture. This machine is old.

Onto the point: I'm getting an occasional fan rev up, with the CPU at 100%. The process is Service Host: Local System (Network Restricted). Recently, I also lost all sound on the computer, which chkdsk /f /r was able to salvage. I have a feeling these might relate to a same problem.
I researched, and found out that sfc /scannow will help. OK. It starts the verification process, but fails at 18% saying corrupt files exist. When I export the sfcdetails.txt from the log, it does not really report which files are corrupt so as to replace them. 00000e22 [SR] Beginning Verify and Repair transaction and then the logfile ends.

Because I cannot complete SFC, I'm told to run DISM, and that is how I ended up here.
When I run Dism /Online /Cleanup-Image /RestoreHealth

Image version 10.0.10240.16384
At 20% an error 1726 with remote procedure call failed.

So I go to dowload the ISO and mount it. It will then give me the .esd
so I'm having my fingers crossed while running Dism /Online /Cleanup-Image /RestoreHealth /Source:esd:F:\Sources\Install.esd:1 /limitaccess

... only to get Image version 10.0.10240.16384
20% an error 1726. Remote procedure call failed.

Help me out here. What is going on with this machine and how can I get healthy system files without wiping the machine?

Thanks.

:)

 

SFC /scannow and DISM not working

Ok I will try that, but my computer prompted me to restart to repair it. Now I can't seem to get on because there is no 'Skip' option. I left it on overnight to see if chkdsk would finish, but in the morning it told me to restart because Windows couldn't
start properly. Which meant repeating the process. Any way I can stop it?

EDIT: I managed to get back onto it by unplugging all usb cables, do you think there might be an issue with my keyboard or something?

 

SFC /scannow and DISM not working

Major file system corruption. I would run it again to see if it has re-occurred and if so the HD may be failing

For the second test (which is more important) go to the HD maker>download>run

I cant tell you which opengl it is.

 

Problem solved with the Windows 10 fall update 1511.
Alhough installing the update would always fail after 22% and revert back to the old Windows.

I only managed to run through the install when I let the program delete every program file, setting and driver I had, leaving only my own files intact.

Took a lot of time and patience, but SFC now runs without errors, so the system is fine.
