Had a working HPZ200 computer which was working fine in one room. Took it
to another room, connected it to an outlet and it started beeping
continuously which it never did before. Took it to the old room and it was
fine. I thought it was a power surge in the second room so used a Belkin
surge protector and it worked fine for few days, but now the HPZ200
started beeping and does not even boot.

Took another functional HPZ200 and it also starts beeping in the second
room. An electrician quickly examined the outlet and mentioned it was OK.

The beeps are constant. I re-seated the memory chips, ran a diagnostic on
them, disks and it all came out OK. Both computers were working very well
and never had an issue.

What could be causing 2 working computers to beep constantly when taken to
the outlet in second room? Can it be a voltage spike despite using a surge
protector or is it insufficient power in the outlet?

Maybe it requires WiFi to boot? HPZ200 is a workstation. See if you can roll
it powered up, to a point where it starts beeping.
