This.

It can be a loose backstab in a receptacle upstream, or even a loose wire inside a wirenut that LOOKS like it's tight. Could be a loose terminal screw in the panel. Especially check...

That's my first thought. What brand breaker is currently installed and what color is the TEST button? As an aside, have you ever tested them?

No, the older NEMA 10 devices are also 120/240 V. They have a neutral, but no dedicated ground. The chassis of the dryer was bonded to the neutral at the point where the cord is connected.

Don't forget to also eliminate the possibility that the computer is plugged into a switch-controlled lighting receptacle, especially if the switch has been replaced with a dimmer or occupancy sensor.

A 15A receptacle is only allowed on a 20A circuit when there is more than one receptacle on the circuit. If it's a dedicated receptacle on a 20A circuit, it must be a 20A receptacle. The difference...

Make them far enough apart that something mounted to one isn't in the way of the other, but they can be mounted side-by-side, if you want.
