Congrats, your power supply is failing.  I'm doing some looking at repairing the Samsung one in my dual 1.25 as we speak.  It used to come on using the button on an ADC display, but i transported it and now it won't boot at all anymore.  My dual 1.42 will still work most of the time, but I have to leave it plugged in all the time.

I've been considering replacing the guts with the guts of a good ATX supply and adding one of these to the 5V standby to supply the 28V circuit:

If one is actually going to use an ADC display, then adding one of these to the 12V circuit (plenty of excess 12V capacity in modern supplies) as well, and isolate each of them with a hefty (high current rating) rectifier:

I won't get to this idea any time soon, so I thought I'd throw it out here for others to try, if they like.
