I'm having my son's pc build with below components. So far no luck: it will give 5 beeps on start up and no display. The computer store tried updating the bios, but that didn't help either. It's also not the GeForce. They think probably the motherboard is defective. It all should work and all components should be compatible. So I'm having the motherboard replaced for a new one. In the mean time: any ideas on what else could be the problem? In case I get a replacement motherboard and it still doesn't work?
