Hello everyone!

 

 

I tried to analyze on a website but the results are quite a bit advanced for my level of expertise and I did not really understand how to read a crash dump, so if I may, I will upload it here for you guys/girls to analyze it for me.

 

The culprit is Windows Explorer, it crashed and automatically restarted. At that time, I was browsing on chrome with multiple tabs open (~12), but I don't think that's the main problem.

The OS is installed on the SSD and the HDD is used for storage, mainly everything that is not related to video games, but right now the drive is fairly free (moved everything to the external HDD for backup).

I have 2 partitions, 1 for the SSD and the other for the HDD.

 

My Specs:

 

OS: Windows 10 Education/Enterprise 64-bit 1703 (Creators Update)

CPU: AMD Ryzen 5 1400

Motherboard: MSI B350 Tomahawk

Graphics Card: MSI GeForce GTX 750 Ti N750TI-2GD5OC/V1

Memory: Corsair Vengeance LPX Black 1x8GB DDR4 2400 MHz C16

SSD: Samsung 850 EVO 120GB SATA-III

HDD: Seagate Desktop 1TB 7200 RPM

 

Feel free to tell me if there's anything else you need to know. Thank you!

I'm not real good with user mode dumps (such as this)

And, there aren't any symbols available for the Creators Update build (15063) yet.

Regardless, I'll give this my best attempt.........

 

The dump file says it has problems with nvwgf2umx_cfg.dll

While this is not a definite diagnostic result, IMO it implies a difficulty with an nVidia program.

 

So, the first step would be to:

- download a fresh set of the latest, W10 compatible drivers for your video card from nVidia.com

- uninstall the current video card software and drivers from Control Panel...Programs and Features.

- install the freshly downloaded nVidia drivers

- test for further explorer crashes.

 

In the event that that doesn't help, try this free tool:  http://www.nirsoft.net/utils/shexview.html

Use it to disable ALL non-Microsoft Windows shell extensions (DO NOT DELETE THEM!), then reboot and see if that helps.

If it does help, then re-enable the shell extensions a few at a time until you find the culprit.

If it doesn't help, then post back for further suggestions.

 

Just FYI - here's the WinDbg output (w/ !analyze -v):

Hello,

 

 

First of all, I would like to thank you for trying to help me. Secondly, I apologize for the delay in response, I was quite busy and couldn't really had the chance of getting here.

Now, onto the topic: I just reinstalled windows fresh including the drivers after I changed the platform to AM4 (Ryzen) and that crash happened with a fresh install. It must have been something that is not really worrying as it did never happened to me ever again. Who knows what happened? But it's fine now.

 

I was just curious what might have caused it, so if it will ever happen again, at least I have an idea of what might be causing it, so that's why I started this thread! :)

 

Thank you and I wish you all the best! Take care!

 

 

Sincerely,

Botezat Robert-Andrei

Unfortunately, I really don't know what caused this.
I would suggest setting a System Restore point and making a full-image backup of your system while it's working well.
That way, should this problem come back, you'll be able to revert without having to reinstall everything.

More info on backup strategies here:  http://www.bleepingcomputer.com/forums/f/238/backup-imaging-and-disk-management-software/

Yes, I always do a full system backup of the OS after I install all the drivers and configure it the way I want it in case anything goes wrong later, I can use it to restore with no problem!

 

Thank you again for all the help and assistance you gave me. I wish you all the best!

 

 

Sincerely and all due respect,
