Hello and welcome to the forum. : )

Your upgrade looks the problem, updating bios could help.

Common for all your minidumps:

Probably caused by : ntkrnlmp.exe ( nt!KiDoubleFaultAbort+b2 )
PROCESS_NAME: sidebar.exe
FAILURE_BUCKET_ID: X64_0x7f_8_nt!KiDoubleFaultAbort+b2
This means a trap occurred in kernel mode, and it's a trap of a kind that the kernel isn't allowed to have/catch (bound trap) or that is always instant death (double fault)

Stop 7F, 0x00000008 (double-fault) error occurs because of a single-bit error in the ESP register

This problem occurs if one or more of the processors in the computer:

* Require a microcode update that is not applied by the computer's basic input/output system (BIOS).
* Are damaged or defective.
* Are operating outside their specified ranges for temperature, power, or other

These drivers are not the cause of the error, but do update them as they are too old:

I would definitely remove the Norton/Symantec in safe mode using the tool found here:

Download and run the Norton Removal Tool to uninstall your Norton product | Norton Support

Those old drivers Cybercore mentioned should be updated because they could be the actual cause too.

Reboot to normal mode and install MSE to replace.
