Computer Blue Screens or Shut Offs when I lock it

1) The latest bugcheck was 3B.
2) There were recurrent hardware drivers in the latest dump.

3) Temporarily turn off Windows updates of non-Microsoft drivers:
Enable or Disable Driver Updates in Windows Update in Windows 10 | Tutorials

4) See post #67 for the method to uninstall and reinstall using DDU

5) Uninstall and reinstall the AMD GPU drivers:
atikmdag.sys
atikmpag.sys

6) Make sure the replacement driver is different from this versions:
24.20.11016.4
24.20.13001.1010

7) Some computer's are able to display using the motherboard without a GPU card.
Determine whether this is or is not possible with the motherboard.

8) Sometimes GPU drivers participate in the crash without causing the crash.
If the GPU drivers are recurrent cause of crashes with different drivers there may be underlying hardware problems.
Performing a swap is a useful method for testing the hardware.
Two tests are performed:
A new card is tested in the problematic computer.
And the AMD GPU card from the problematic computer is tested in another computer.

9) Plan to test the DIMMs as they need to be ruled in or ruled out.

Got two more this morning. One seemed to occur when I was running Matlab with parallel processing. The BSOD occurred right as the program ended.

There were two recurrent drivers in the latest 3B bugcheck.
The Realtek driver was earliest in the crash.
rt640x64.sys
atikmdag.sys


With windows updates of non-MIcrosoft drivers off see if you can find another Realtek driver that is different from
10.28.615.2018
10.19.627.2017

Forgot about this thread. Turns out the problem was bad ram though I wasn't getting errors on the memtest. Swapped out the ram in my home computer with my work computer and my home computer start BSOD (this whole thread was about my work computer). Bought new ram and haven't BSOD in months. Thank you all for your help

Thanks for the feedback. This is useful confirmation for us and was what I suspected in post #70.
