My computer has worked great for me the past 8 months. Its a custom pc. I used it for gaming high end games like skyrim with mods BF3 etc. Today I turned on my pc and I noticed 5sec later it turns off. Then it turns on again after 2sec and all I get is a black screen with A2 at the bottem right. I tried replacing the monitor and nothing. I dont hear any beaping sounds. My MoBo shows A2 where the CPU temp is suppoed to show. I left it on for 30min and screen stays the same... I turned off and on a couple of times and nothing. My specs are below in signatures. Also I have Win7 Ult 64bit. Please help thankyou!
