The latest two mini dump debugging displayed dbx.sys as the misbehaving driver.
Dbx.sys is related to Drop Box.
Drop box was uninstalled and reinstalled yesterday and should have had new drivers.
Windows driver verifier will be used for several days so if you uninstall drop box and use an alternative software product during the troubleshooting time period that would enable you to continue testing other drivers.
Once all misbehaving drivers have been fixed you can then reinstall software in a staggerd fashion.
One drive is an alternative to drop box.
So uninstall drop box software > restart windows driver verifier to find the next misbehaving driver
The memory dump debugging also displayed the Nvidia GPU drivers: nvlddmkm
1) Uninstall the Nvidia GPU driver using DDU (display driver uninstaller)
2) Re-install the Nvidia GPU driver from the Dell website
3) If there are recurrent problems with the Nvidia GPU the DDU will be used again and the source will be the Nvidia website.
What is your specialty?
If you have a large period of time where you can test one of the hardware components, the RAM, with Memtest86+ version 5.01 that may be needed. For example the weekend. There is 32 GB of RAM. The best test is testing the multichannel capability of the motherboard with both RAM modules at the same time. If the downtime is too long then one RAM module can be tested at a time but the multichannel capability is not tested. Eight or more passes are required for proper testing to reduce the number of false negatives. The testing is not done by time but by passes. The memtest86+ version 5.01 testing takes 1 -2 hours / GB RAM. A portion of the RAM testing can be done overnight. Testing can be aborted if there is just one error. Then one module is tested at a time to find the malfunctioning RAM module. The RAM testing may be needed in the future. Memtest86+ - Advanced Memory Diagnostic Tool
