Hello! I am a computer enthusiast and i wanted to give my dad an uprade from his core 2 duo pc. I bought an asus P9X79 Deluxe and an I7 4820K. Later i found out the i7 is broken, i now have an 100% working i7 3820 but it still is faulty( postcode 00 ). I belive the motherboard is fine , and the processor is fine as well, and the psu might be the one to blame . He has an asus a-55-ga psu ( 550w max) ad i have the option of lending a corsair CX500 . Any ideas are welcome
