Hello, I have an Asus M4A785-M This is a new build. I connected all my peripherals, booted, computer stayed on for less than a minute then everything shut down. POST stayed on long enough to see that everything was recognized. One by one I disconnected everything until I'm down to 1stick of Ram, 24 pin power connector and 4 pin Atx. I also tried another power supply. Same problem--System speaker gives me a normal sound on power on and gives rapid beep when I remove all Ram. When I disconnect the 4 pin ATX the CPU fan and the PSU fan have stayed on for over 24 hours. The only things left on the front panel connector is the speaker and the power on button. I'm stumped...
