First, Bill, thank you for reply at all. I see you're the only one with the courage to wade into this mess.
To clarify where things stand now: •One 867 works perfectly. •The 1.25 used to boot and run, except it didn't recognize its DVD drive. Now it gives the 3 beeps. •The other 867 used to give the 3 beeps. Now it does nothing but run its fan. No chime, no beeps, no power-on light. After about 10 seconds, the fan switches to Tornado mode and stays there. Your suggestion about using the good machine as a test bed for parts seems like a very smart one. Thanks.
