I'm building a computer right now for my apartment. It's got an ASUS A8V Deluxe Mobo, AMD Athlon 64 3000+ 939 Pin, 1.5GB Kingston PC3200 RAM, 200GB SATA HD, and so on.. All the parts are brand new, PSU is MGE Vigor 450 Watt. I am not sure if I didn't hook the speaker up right to it or not. But when I power it on there are no POST Beeps. Any ideas?
