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: 0000001b, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000001, 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: 81dcffe9, address which referenced memory

Je penche fortement pour un problème matériel (les plus fréquents étant ram / alim). Ca peut aussi venir de la carte mère ou d'un overclocking.
