Inizialmente si trattava della RAM, che ho prontamente fatto cambiare, ma i problemi non sono finiti.
Ora il pc non si spegne dopo 5 minuti dall'avvio ed è sicuramente utilizzabile, ma ogni tanto si pianta.
Ho fatto il check delle memorie con Memtest86, ho aggiornato tutti i Driver del sistema con DriverEasy, ho eseguito i vari stress test della scheda video e anche della CPU.
Ho fatto una passata con WhoCrashed e il report è il seguente:

This might be a case of memory corruption. More often memory corruption happens because of software errors in buggy drivers, not because of faulty RAM modules.

Questi errori sono diversi l'uno dall'altro, alcuni sembrano interessare la scheda video, altri la memoria... Mi viene da pensare che sia un problema legato alla scheda madre.
Ad ogni modo, questi crash sono imprevedibili, a volte il pc dura ore ed ore senza dare problemi.
Idee?
