I put together a new pc the other day with old pieces and new. at first i was getting an FF code on my evga 780i sli mother board i bought a new PSU and it worked wonders everything started up and games were working as they should. after about a day my PC was asleep and i woke it up as i did this it shut down and never turned back on now im getting a different error code on the Mother board A0 and when i hit reset i get 2D or 20 whatever it says. this is not my video but its exactly whats happening to my PC with the same mobo. http://www.youtube.com/watch?v=m_kMmRxDaIY i think im going to have to get a new MOBO or CPU im not sure
