Not quite - at least, not if you want a full answer.

The answer is this:  almost all such devices will "work" without a
ground.  You could cut off the ground prong of the power cord, plug
the remaining two prongs into a non-grounding power wall socket, and
the device would "work".  It would run.

However, it would not work *SAFELY* - at least, not in a legal sense.
The device (PC, refrigerator, power tool, etc.) would have lost one of
its designed-in safety features - that of a safe grounding of the
chassis.

If such a device were to develop an internal short circuit when it
still had a ground, it would probably blow a fuse or trip a circuit
breaker... annoying perhaps, but it would "fail safe".

If you cut off or otherwise disable the ground prong on the plug, and
the device develops an internal short circuit... the next time you
touch it you can get a very severe shock and die.  The device will not
"fail safe".

So, the device will still "work" without a ground... but what it
"works on" may be the job of getting ready to kill you.

This is why you really should not try to run your PC without a ground.
It might have a grudge, and decide to electrocute you if given the
opportunity.
