Hello Scamander and welcome!
- Possible memory corruption or driver as UNEXPECTED_KERNEL_MODE_TRAP often are caused by those. Our first step would be checking your sticks, one thing at a time as people used to say.
Follow these instructions.
RAM - Test with Memtest86+
Pay extra attention to part 3.
Code:

*******************************************************************************
UNEXPECTED_KERNEL_MODE_TRAP (7f)
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). The first number in the
bugcheck params is the number of the trap (8 = double fault, etc)
Consult an Intel x86 family manual to learn more about what these
traps are. Here is a *portion* of those codes:
If kv shows a taskGate
use .tss on the part before the colon, then kv.
Else if kv shows a trapframe
use .trap on that value
Else
.trap on the appropriate frame will show where the trap was taken
(on x86, this will be the ebp that goes with the procedure KiTrap)
Endif
kb will then show the corrected stack.
