BSOD senza apparente motivo

[pasta]

sistema stabilissimo da una vita, praticamente ho avuto una BSOD mentre non face niente:

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: 0000000000000002, A list entry was corrupt
Arg2: 000000000007435f, entry in list being removed
Arg3: 000000000013ffff, highest physical page number
Arg4: 0000000000000001, reference count of entry being removed

p.s il mio dump si legge correttamente o ho qualcosa che devo correggere per consentire una migliore interpretazione del dump?

 

[dedoRR]

il tuo bug si chiama Vista.... :lol:
dai scherzo..è successo una sola volta o ne hai avute altre ultimamente di bsod?

- - - Updated - - -

prova a fare un pò di cicli con memtest e vediamo che dice..

 

[weltall]

Sembrerebbe qualche incompatibilità con dei driver....o potrebbe essere "soltanto" vista :D
hai per caso installato nuovo hardware di recente?

 

[Federico83]

ma sicuro che sia vista? leggendo qui Windows 7 Kernel Version 7601 non è Vista ... cmq usa whocrashed e vediamo cosa dice che con quello che hai postato non si capisce nulla edit leggi qui http://support.microsoft.com/kb/291806/it

 

[pasta]

si tratta di Windows 7

 

[Federico83]

hai letto quanto ti ho riportato nel link?

 

[pasta]

si, non sebra ci siano particolari indicazioni, tranne le normali verifiche di incompatibilità di alcuni componenti, e nel mio caso nulla di nuovo, tantomeno nel reparto drivers, inoltre riguarda windows 2000...

Analizzando il minidump invece mi sembra di aver capito che il problema è stato prevx.exe, ed infatti stavo controllando un file lanciando prevx da pulsante destro...
