Both BSoDs were caused by Memory_Corruption, which means bad RAM. Do as suggested above and run Memtest86+ - Advanced Memory Diagnostic Tool.

PFN_LIST_CORRUPT (4e)
Typically caused by drivers passing bad memory descriptor lists (ie: calling
MmUnlockPages twice with the same list, etc). If a kernel debugger is
available get the stack trace.
Arguments:
Arg1: 00000002, A list entry was corrupt
Arg2: 00023226, entry in list being removed
Arg3: 000cf77f, highest physical page number
Arg4: 00000020, reference count of entry being removed

IRQL_NOT_LESS_OR_EQUAL (a)
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.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: 0000001c, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000000, bitfield :
bit 0 : value 0 = read operation, 1 = write operation
bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: 82ea6b38, address which referenced memory
