Topic: chiamata skype arresto pc

Buonasera a tutti...
mi è capitato un problema abbastanza strano almeno per le mie conoscenze...
si tratta di un pc desktop abbastanza vecchio...quando cerco di effettuare una chiamata con skype inspiegabilmente il pc si spegne e si riavvia!
Ho fatto le varie scansioni....con avast nessuna minaccia, con antimalwer 2026 adware risolti e ho fatto anche una bella pulizia con ccleaner...
Non riesco a capire da cosa dipenda...ho fatto una ricerca su internet e ho letto da qualche parte che potrebbe dipendere anche da un surriscaldamento
Se potete darmi qualche delucidazione vi posto il log di hijack.
