Corrupt files on brand new install, unable to fix

Hey everyone,

I've reinstalled windows a couple of days ago and after installing all my drivers and files and applications, I decided to run sfc /scannow just to be sure everything went right. It found some corrupted files, and was unable to fix them. Rather than try to diagnose the problem, I decided to just reinstall again. So I did, and right after I reinstalled windows I ran sfc /scannow again. Again it found corrupted files! I have no idea where they're coming from, since the install is completely fresh. It's even installed on a new SSD I bought a couple of days ago.

I tried running DISM, but that failed as well. Here's the output from Command Prompt:

Code:

Microsoft Windows [Version 10.0.10586](c) 2015 Microsoft Corporation. All rights reserved.


C:\Windows\system32>sfc /scannow


Beginning system scan.  This process will take some time.

supported in offline servicing scenarios.

The DISM log file can be found at C:\Windows\Logs\DISM\dism.log


C:\Windows\system32>

And the logs are attached to this post. Does anyone have an idea what might be causing this? I've already checked the SSD's S.M.A.R.T. status, since I figured it might have been delivered faulty, but it reports no errors.

I'd take a look at the logs myself but I'm unsure what I should be looking for. Thanks in advance!

You need the Install.wim which can be obtained by downloading the ISO from Tech Bench.

https://www.microsoft.com/en-us/soft...load/techbench


Once you have the iso downloaded, right click at the ISO > click Mount > leave it there.
Then open the elevated command prompt and copy and paste this................

Dism /Online /Cleanup-Image /RestoreHealth /Source:wim:H:\sources\install.wim:1 /limitaccess

Note : H is the drive where the iso is mounted. Change it if your driver letter is different.

When it is completed, you should get the report that the operation is successful.
Now run the sfc /scannow again. It should be ok this time.

Have you tried memtest or something like it to test the memory?

Hi Qub1,

I've had a look at your CBS log and the corrupt file turns out to be opencl.dll. This is a known problem and is due to the graphics card driver changing the file. It actually does not cause a problem and I believe a future Microsoft update will fix the issue so that the sfc scan will not false alarm. Do you have an NVidia graphics card by any chance?

Thanks for the info, I'll try this if I run into any further issues. As per phil's answer, if it is a known issue, I'd rather not run any "fixing" operations on a fresh install, as they might cause more problems.

Ran one last week, it passed.

Ah, so that's probably what's causing the issue, as I do indeed have an NVidia graphics card (GTX 780). If it's a known issue like you said, I think I'll just ignore the error for a while. Is there any ongoing thread or discussion where I can follow the progress of Microsoft fixing the issue? Perhaps on the Microsoft site?

Have a look at post #226 on this thread:

Latest NVIDIA GeForce Graphics Drivers for Windows 10

Some of the insiders have discovered the issue has been fixed on their latest builds.

Thank you so much for posting your concise instructions how to solve this problem when the sfc/scannow cmd reports finding corrupt files and perversely states that it can't (won't) fix them. Using the Win 10_1511 iso for RestoreHealth worked for me.

You are very welcome.
Good to know both of you have the problem resolved.
Happy computing.
