So me and a friend who built a computer over 10 times were building this rig. At the end everything was in place. The MoBo gave light, everything plugged in, all components in place and now. We tried to turn on the computer. It didn't start, so he said the RAM might not be in place correctly. So we put the 2x 4GB corsair Vengeance out of the MoBo and then putting it back in. BAM computer started and then turned off in a seconds. The screen wasn't plugged in yet so we didn't know if it said anything. Then we tried EVERYTHING. Weird part is that all the wires were correctly, all the MoBo lights were flashing. BUT there was no MoBo sound! I know it should be giving a beep when working. So we started from scratch. Same problem. Does anyone know if the MoBo is broken? EVERY component was fresh from their package, bought them a day ago. I'll also put the rig. Everything fits for a socket 1155.
