I have some problems with my Rainbow Runner G series and my motherboard Abit ZM6. The TV tuner and the audio don't work. I red somewhere that the motherboard isn't able to feed the RR with a sufficent amperage. The RR works fine on my second computer that has a Asus P5A-B motherboard. How can I by-pass my motherboard and feed the RR directly from the AC-DC transformer?
