[HELP] riavvio continuo

[lello89]

Salve a tutti, è da un po di tempo che si verifica un errore...il mio pc si riavvia di continuo(soprattutto quando è sotto sforzo) e nella schermata blu mi esce il seguente errore: PFN_LIST_CORRUPT.
Cercando di capirci un pò di più ho aperto il minidump...e in pratica ho capito che l'errore deriva dal file NTOSKRNL.EXE...

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: 00000099, A PTE or PFN is corrupt
Arg2: 0000ff16, page frame number
Arg3: 00000001, current page state
Arg4: 00000000, 0
