So I this old rig because I want to have fun with quake 3 arena over LAN network with my friends in my basement but this pc does not want to work. It is a very strange PC I must admit on the motherboard it has 2-4pin connectors one is for CPU and other one is right next to the 20 pin power plug. Someone plz tell me how to wire this thing up and give me some advice. And when I try to turn it on the light on the power button does not glow neither do i get fan spin up on the CPU fan or PSU fan. The PSU does work tho i tested it in another computer and i got fan spin up out of that PSU and i tried diffirent PSU's in the pc.

 

Is there a battery on the motherboard, usually for maintaining settings and clock during a power outage? A dead battery can prevent booting. So can a lot of other things!
