XPS 8930, Device Manager errors

Sounds like you still have a hardware or core Windows problem.

I agree, there's still a problem. Something is preventing the IntelPPM.sys driver from loading so you've just substituted a generic driver, but this needs to be fixed. 

It sounds like a Registry error, but at the least, did you update or reinstall the chipset drivers and try using IntelPPM.sys again?

You may actually have to reinstall Windows, so back up all your personal files on external media and make sure you have the Product Keys for all your software, eg Microsoft Office, first...

 

 

I did update and reinstall the drivers multiple times.  In every case, the Intel PPM driver caused the device manager error 32 problem to recur.

In terms of a registry problem, any ideas where to look?  I agree that my use of the generic processor driver may well be a band-aid fix that just removes certain symptoms (such as the error 32 code), but does not address the underlying cause of the problem.

I use this machine on a daily basis and to reload Windows 10 (with its numerous updates), all the applications on the machine and ferret out and restore the data files is a monumental task (in terms of the time required) that I simply can't do at the present time.  I wish there a less drastic, more efficient solution than nuke and reinstall everything.

By the way, I did run the Microsoft SFC utility twice and it found no damaged Windows/system files.

Make sure all your files are backed up...

Uninstall the generic processor driver, then install the Intel PPM driver, and click the button to scan for hardware changes at the top of the Device Manager window. Reboot.

Does that help?

Check out this article: https://support.microsoft.com/en-us/help/888731/how-to-determine-the-type-of-processor-that-your-windows-server-2003-x

While the article is about Windows Server, I looked in the registry and found for my computer running Windows 10 Pro for PROCESSOR_IDENTIFIER the following: Intel 64 Family 6 Model 94 Stepping 3, GenuineIntel. My processor is an i7-6700.

Thanks for your suggestions. Both the Processor_Identifier in the registry and the SET command from the Windows command prompt returned the same values - "Intel 64 Family6 Model 158 Stepping 10 Genuine Intel." I cross-checked this, and it is definitely the Intel Core i7-8700 processor. I also ran an Intel program called the "Intel Processor Diagnostic Tool." It also identified the CPU as the i7-8700. The actual final (I hope!) solution is described in my comment below.

I believe the CPU driver problem has been solved, although I can't explain exactly why. What I did was to select "Update Driver" in the Device Manager for the processor (which I had done ten days or so ago without anything improving). I then chose "Search for Updated Driver Software." Eventually Windows found an "updated" driver, which turned out to be the Intel PPM.Sys driver that had caused all of the Device Manager 32 errors in the first place. I did this for all twelve incidences of the i7-8700 CPU, then rebooted the computer (to allow the Intel driver to be loaded by Windows). Much to my surprise, all of the Processor error messages that had been found in the Device Manager were gone, as were the yellow exclamation marks. The CPU benchmark scores also improved. The big mystery of course is, what happened to cause this to work as it should have in the beginning? The Intelppm.sys driver had the exact size and data it did before (in other words, the file itself did not appear to have changed). Perhaps it was something in one of the recent Windows 10 update rollups, who knows?

Glad you got it sorted.

Out of curiosity, do you know if the Intel driver Win 10 found is the same version number as the one you kept installing?

Maybe Intel quietly pushed out a new driver to fix problems like the one you were having...??

Just a random thought...
