kdcom.dll non mi fa avviare il PC

[slksurf]

All'avvio di Win7 mi appare un messaggio relativo a kdcom.dll e riesco ad avviare il sistema solo disattivando le firme digitali.

Ho provato a fare una scansione del registro e del sistema, ma non riesco a risolvere.

Su un sito inglese mi dice di sostituire il file e poi, dal prompt, digitare :"regsvr32 kdcom.dll", ma vien fuori un errore: "Impossibile caricare il modulo kdcom.dll..."

Quello che trovo assurdo e' che per evitare problemi avevo precedentemente effettuato un backup dell'immagine di c: a due giorni prima (e non avevo problemi), ma anche ripristinando tutto c: il problema permane.

Non so piu' che fare ( a parte formattare)

INTERNAL_POWER_ERROR

....

STOP: 0X000000A0 (0X00000001, .......)

[rabuffi]
