I am ready to conlcude that the power supply may have died as Jeff suggested. Since I last wrote in about this I pulled the PS cable from the MoBo and left the battery out for several days with a test lead shorting across the contacts in the holder. All PCI card are removed, the orignial 32Mb RAM stick is installed, the sound card and ROM were reseated. Then I pressed the cuda switch for a solid minute before inspecting the jumper settings again. I am looking for stock settings for PCI and main bus speed and added a 5x multiplier to get 333 MHz. The 350MHz zif from the B&W should be happy with that.
I still get only about one second of fan spin when I press the power button, then nothing. I guess this is not a lucky time for computer PSUs around here. I have two PC's both with PSU that appear to have died in the last 2 months. Is there a good way to test a power supply independent of the computer, with a voltmeter and the pinout diagram for instance Broos [email protected] wrote: > On Dec 3, 12:10 am, Bruce Godfrey <[email protected]> wrote: > > >> However, in my web surfing the topic today I realized that my attempt to >> reset the MoBo was not done correctly.
