My good old 5 year old BH6 based rig, running a C-566 at 850, just crashed a few nights ago while I was at work (more often than not, I just leave my computer running when I go out).
When I came home and sat down at my desk, I wiggled the mouse to turn on the monitor, and nothing happened. I heard the fans running, and looked down. Power light's on, and, oh, that's odd: the HD light is on solid. Great, I thought. It's probably time to clean that heat sink again.
Next, I pressed the reset button. Nothing. OK, so I pressed and held the power button. I waited. Hmmm. . . The power should be turning off by now. This is kind of weird. . . But crashes can do odd things. . . So, as a last resort, I reached back and pulled the power cord. As I waited the customary 3-5 seconds before I plugged it back in, I noticed that I wasn't hearing the HD spin down.
When I plugged the power cord back in and pressed the power button, I quickly realized that something was wrong with the hardware. I got no picture, no POST, no HD spin, no video signal even (the monitor remained in sleep mode).
In summary, here are the symptoms: When I plug it in, I need to press the power button to get it to turn on. Then the fans all start running (12 volts), but there's no video signal, no POST beep, no HD spin-up (unless I disconnect the IDE cable!), and the HD light just turns on solid, whether or not the IDE cable is connected. The only way to turn off the power is to unplug the power cord or the MB connector. The purple wire to the MB connector has a constant 5 volts, and the red and yellow wires have 5 and 12 volts, respectively, when the power turns on. I can't test the rest of the MB wires, because the harness must be connected for the power supply to turn on.
What'chall think?
Thanks in advance for any help or further insight.
EDIT: The motherboard is toast
. Oh well. It had a good run. See below.
