using a ASUS P4S8X-MX Socket 478 SIS 661GX board with a 2.8 P4. Powered by a Thermaltake TR-2 430w power supply. 1gb (512x2) kingston value ram. All was running fine untill I plugged in the audio plug into the onboard audio connector. The system instantly shuts off. I've tried a few different configs trying to get the thing up and running reseting the cmos everytime. Each time I get about half of a fan rotation, unless I disonnect the P4 connector, then I just get fan spin up. Also, I took out the video card, and am using the onboard video
