OK, i had a BP6 and a celeron 366a lying around, so I decided to build a machine. But I ran into a snag, my BP6 isn't cooperating. Once I got everything into the case and set up, i pushed the power button and. . .my ps powered up and the fans, but thats it, nothing else. So i took it out of the case, put it on an insulated pad and only put chip, RAM, and Vid card in. But again same results. I'm not even getting a beep code (yes my speaker is plugged in ) This is most odd. I started it up again and let it run for a few minuntes. After some time i turned off the power and checked the chip. . .totally cool, not a trace of heat, but the HS on the Vid card was warm. I then tried another chip, but I got the same results. I have also swapped out the RAM and Vid card, sadly no progress. I discharged the CMOS and even went as far as to reseat the Bios chip. I'm at a loss Am I missing someting?
Any help is greatly appreciated
