Innanzitutto controlla l'HD con CrystalDiskInfo. Poi controlla anche la ram con memtest su un banco alla volta.

Potrebbe essere la scheda video oppure il monitor, perchè questa mattina è diventato leggermente azzurino su tutte le viste?
Ho provato ad aggiornare la scheda video ma il problema non si risolve.

Hai installato qualche dispositivo ultimamente, c'è quel driver CPUsb.sys che appartiene a questo produttore

Nel caso disinstalla.
