Just got my parts today. I got the MB out - hooked up the processor - 1st core duo build - got the heat sink hooked up. I got my video card in, and my ram in slot nearest the CPU and it wont post. I got both psu cords plugged into the MB the 24 pin and the ATX 4 pin one. I am certain my PSU and Video card are good, because my new PSU wasnt working and wasnt sure about my new video card, so i removed ones from my current build and stuck them in this one. Also I am bench testing it on cardboard.
