windbg e ntoskrnl.exe

[sigolo]

Il mio problema è che tutte le volte che provo a fare una installazione di un qualsiasi aggiornamento windows ( e sembra solo in quel caso? ), la macchina mi si blocca con una schermata blu. In rete ho reperito alcune info ed ho usato windbg che mi da dei riferimenti in merito al file ntoskrnl.exe.
Premetto che ho gia eseguito questa operazione: http://www.azpoint.net/news/Consigli_per_PC_4135.asp
ma senza nessun risultato.
Premetto che in precedenza ho installato il firewall c.o.m.o.d.o. e il crash sembrava dipendere dal .sys utilizzato da esso, quindi l'ho disinstallato ma i crash continuano in riferimento al ntoskrnl.exe.
Cosa posso fare?
questo è il report di windbg:

KERNEL_MODE_EXCEPTION_NOT_HANDLED_M (1000008e)
This is a very common bugcheck. Usually the exception address pinpoints
the driver/function that caused the problem. Always note this address
as well as the link date of the driver/image that contains this address.
Some common problems are exception code 0x80000003. This means a hard
coded breakpoint or assertion was hit, but this system was booted
/NODEBUG. This is not supposed to happen as developers should never have
hardcoded breakpoints in retail code, but ...
If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG. This will let us see why this breakpoint is
happening.
Arguments:
Arg1: c0000005, The exception code that was not handled
Arg2: f649f9c7, The address that the exception occurred at
Arg3: b99e0a20, Trap Frame
Arg4: 00000000

Grazie per l'attenzione.

probabilmente non è mai capitato a nessuno?
Stò veramente provando di tutto, ma non riesco a venirne a capo!!
Grazie.
