i have an asus p5vd1-c (via pt880 pro/ultra chipset) that does not turn on. when the power button is pressed, the fans jerk as though they were just about to turn on, then nothing. using a multimeter, i can measure the voltage on the processor vrm and for that instant, the voltage goes from zero to 1.something volts (happens too fast for me to read).
when i pull the processor, the board powers up and all the fans spin, but with only the processor and NOTHING else, the board only initiates for a 1/2 second. once it initiates once, pressing the power or reset buttons does not do anything. however, after holding the power button for 4+ seconds (normal atx force shut off), and then pressing power again, makes the fans kick for another 1/2 second as though the board was originally powered, but measuring any point on the board with my multimeter shows 0 voltage....
i've reset cmos, pulled the battery, removed power and let the system set for a couple hours and then tried again.
i have no other 775 boards or processors to try.. all else in the computer is tested as good in my amd setup.
