BSOD - ntoskrnl.exe

Bonjour,

j'ai de temps en temps un écran bleu (BSOD) après une veille prolongée que
j'analyse par la suite avec WinDbg:

BugCheck 1000007F, {d, 0, 0, 0}
Probably caused by : ntoskrnl.exe ( nt!PARTITION_SYSTEM_GUID+f )

Par contre, je n'ai jamais de BSOD sur une session démarrant à froid
(faisant suite à un arrêt et non une veille prolongée).

Avez-vous une idée pour analyser plus en avant ce qui coince ?

UNEXPECTED_KERNEL_MODE_TRAP_M (1000007f)
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.
Arguments:
Arg1: 0000000d, EXCEPTION_GP_FAULT
Arg2: 00000000
Arg3: 00000000
