Most "computer repairmen" are not really electronic techs. They are
amateur parts changers who turned a hobby into a job. That is evident
in your friend's diagnosis. There is no scientific basis for the claim
that personal computers need a ground to operate properly. That has
been true since the inception of personal computers. A good ground is
a good idea, but not to make the computer free from "static issues" or
to enhance reliability.

You don't need a ground to avoid "static issues" either.

Static electricity is when two objects are at different electrical potentials.
Connect them together and there is a brief electrical current until they
are at equal potentials.

When installing static sensative devices into a computer, one doesn't need
to be grounded. One simply needs to be at the same static potential as
the equipment. For example, after removing a memory module from its
antistatic wrapping, hold it in one hand, with the other touch the computer's
case. Module, human, and computer are now all at the same static potential
and there will not be a equipment damaging current flow when the device is
installed.

I live in bone dry phoenix arizona and have to do something like this every time
I kiss my wife goodbye before going to work. I touch her hand first so the
static zap is there instead of at the kiss.

I believe that's exactly what I said.

I wasn't disagreeing with you.

A ground might be necessary for some surge protectors to work. The
computer that's plugged into it, not so much.
