Aggiornamento: in attesa di fare un test cpu e un test sulle memorie, ho fatto un test vga (con ATITool,un programma free, http://www.techpowerup.com/downloads/Tweaking/ATITool ).

Ho provato a fare 2 test presenti nel programma ( "find max core" e "find max mem" ).

Questi 2 test fanno apparire un immagine 3D in una finestrella. Risultato: dopo neanche un secondo dall apparizione del 3D mi crasha il pc (stessa modalità descritta nel post di apertura).

Questi sono i log registrati dal programma prima del crash del PC:

e crash anche con questo test.

Qualcuno sa dirmi di cosa può trattarsi (ram, scheda video, driver...)?
