Im having constant blue screens even at idle (maybe blame luna for an attempt at OC'ing my cpu) Specs i5 2500K 8GB ram asus p8z77-v Nvidia GTX 670
Technically i underclocked it since the guy who you bought the motherboard off didnt clear the CMOS and it had a 4.4ghz overclock on which i reduced since you said you didn't want a big overclock, I will remove it but if it happens again write down/take a pic of the blue screen.
