DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.

I have seen much in the way of frustration and little in the way of actual solutions with various attempts at resolving this particular Blue Screen. Some have reported solving the problems by updating the Nvidia Driver, while others have reported success in resorting to an early version of the Nvidia Driver. I suppose there is a possibility of driver corruption here so which ever option you choose to pursue I would suggest using
DriverSweeper to remove any remnants of the current installation.
SECOND DUMP:
Blaming Memory Corruption (Again);
Code:
BugCheck 50, {fffff88005a5c455, 1, fffff9600012e958, 0}

PAGE_FAULT_IN_NONPAGED_AREA (50)
Invalid system memory was referenced. This cannot be protected by try-except,
it must be protected by a Probe. Typically the address is just plain bad or it
is pointing at freed memory.
Arguments:
Arg1: fffff88005a5c455, memory referenced.
Arg2: 0000000000000001, value 0 = read operation, 1 = write operation.
Arg3: fffff9600012e958, If non-zero, the instruction address which referenced the bad memory
address.
Arg4: 0000000000000000, (reserved)
