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: fffff10006299618, memory referenced.
Arg2: 0000000000000001, value 0 = read operation, 1 = write operation.
Arg3: fffff80002f22316, If non-zero, the instruction address which referenced the bad memory
 address.
Arg4: 0000000000000007, (reserved)

Test your memory using memtest86+ preferably overnight for 8 passes:
RAM - Test with Memtest86+

Post back results

For how long and how many passes?
How many modules do you have?

Alright.
Lets insert one bye one each and see how your computer performs. Once you've tested them that way insert all together and see if you get bsod again.

Time for a replacement - again

See you soon and best of luck :)
