Re:Re: [cobalt-users] NASRaQ Won't Boot - Freezes at power-up

["Darryl Hafermalz" <dhafermalz@xxxxxxxxxxxxxx>]

Thanks for the info.  I hadn't considered the power supply, but after
examining it someone has definitely removed the heat sink (stripped screw
head) in the past and soldered in a new component.  I'm not sure if the
factory may have done this or the previous owner.

I'll test the pin-outs to the mainboard for correct voltage and current.

I've got a NASRaQ at home that died recently with the same symptoms.  I
tried
swapping various items until I found the problem.  It turned out to be a bad
power supply.
