PCIMPOTS, You can update the bios on the computer. You may want to consider formatting and installing Windows 7 on the system. Getting a Fresh Windows Installation will more than likely resolve the issue. 
Hello, More and more often (almost every day, now), my Inspiron 15R N5110 will freeze and, sometime, get a blue screen, and shut down completely. Windows 7 is up to date. BIOS not updated (5 years, now, I think). Should I update the BIOS to A11 (the last one) ? Any concern with Win-7 ? Any concern with AVG (virus protection) ? Any clue or your experience wil be appreciated,  Marcel
