ok so here is the situation I have gone down the list of ways to check if i did somthing wrong. All the cables are in correctly and the componets are not doa. I tested it all with a old AMD athlon II processor I have 3.2ghz and 3 cores. Started up just perfectly. Then I put the 8 core in and nothing. The computer doen't even beep. the fans start up the ledslight up telling me everything is fine and then nothing happens. ever. at all. The bios doen't even show up. I don't know what to do. how can I get my computer to boot. The asus website says that my ram graphics card and cpu are all compatable yet nothing happens.
