How do I fix a system crash with WHEA_UNCORRECTABLE_ERROR?
The dump references pshed.dll which is an internal hardware error and may be tricky to nail down so that means motherboard or CPU. I used nirsoft.net Blue Screen View on the latest (by date / time) dump you left.

WHEA error usually means a hardware issue.
This is an Internal unclassified error as inferred from the dump, getting to the root cause can be tough.
Severity : Fatal
Error : Internal unclassified (Proc 4 Bank 4) Status : 0xba00000011000402
At this point, given the error, I suggest you get the machine serviced and see if the repair shop can give you a workable answer.
One thing to try prior to taking it to the shop would be to make a bootable USB key for memtest86.exe and run several passes to test memory.
