mat-debug-xxxx.log files

Did you try the Safe Mode FIX?

I am having this issue too on all of my win10 machines -- and none are dell  -- Does anyone have a clue what app is creating these files --- it seems to me that mat-debug-xxxx.tmp  the xxxx in the name is the PID  that created it  anyone with a clue to this issue

I would still like to find out what application generates "mat-debug-xxxxxx.log" files, however.

The FIX that has worked so far is this: I ran msconfig.exe, checked boot option box as "Safe Mode", and checked "minimum", then restarted the computer into Safe Mode and ran disk cleaner, then looked in temp file (found no files in my Temp folder, having cleaned them out before I restarted) and confirmed there were no files. Then I unchecked boot from Safe mode and rebooted back into normal windows 10.  Viola! no more mat-debug files! This beats uninstalling and reinstalling stuff!

Reinstalling graphics driver will fix this issue, if it didn't reinstall the audio driver, chipset driver and firmware driver will fix it.

It seems like its happening due to unsigned driver.

For more information regarding the fix  you can follow the below guide

Method 1

To uninstall a graphic driver.

In search bar type as “add or remove programs” (without quotes)

Open the result

In it search for **"Nvidia"**if you have Nvidia graphic card and if its AMD graphic card  search for "AMD"

Then uninstall all the results you find there related to the search.

Once uninstalled restart the system and visit your manufacturers website for downloading the available graphic driver for your system

Method 2

In case if you are having "Intel graphics" or you didn't find any results of both AMD and Nvidia you can follow the below guide to uninstall

Right click on the windows icon (Start Menu) 

Select "Device Manager" 

Expand "Display Adapters" 

Right click on each item here 

Select "Uninstall" 

Press the F5 key on your keyboard 

and restart

Method 3

If the above guide didn't work then  reinstall the audio driver, follow the below guide to do so.

3. visit the manufacturer for installation of audio driver

Method 4

If the previous methods didn't help  then  install all the chipset drivers and firmware driverspresent in the manufacture's website.

Method 5

Even by executing all the above guide if the issue is still the same then you can follow the  below method (which is to update all drivers in device manager)

To update all the divers -
