Is it better for the life of the electronics, HDD bearing, and/or monitor to
turn all off or put into standby if I will not be using pc over night?
tks,

This depends a lot on the type of equipment. Is it ALL electronic? |
Electro-mechanical components? The latter usually do have a mechanical
wear mode. Disk drives (depending on the power saving settings)
continue to rotate. Printers usually do not work mechanically when on,
unless actually printing.
Depends on temperature design of systems. High temps speed up failure
rate, but if temp not far from room temp this is not a problem. If
equipment runs hot, it IS. |

That's why I specified.
HDD in standby supposedly does not spin, but I have no way of confirming
that.
Monitor standby is powerdown, but the switch is still depressed and it
blinks its LED. So is it really off?
The boards are still powered, I think in standby. The cpu fun keeps
spinning.
minimal climate control here. Often in lower 80s°F in summer and sometimes
hotter. CPU will power down if temperature goes over a preset limit.

win help says that standby powers down the HDD, but I can not hear a
difference.

You should be able to hear it, especially when it needs to spin back up.

Part of it is on. The high voltage of a CRT, and the backlights on an LCD
would be turned off. Even an LCD usually gets pretty warm with the drive
chips
and backlight on, so if it has been off a while the temp difference should
be
obvious.
The boards are still powered, I think in standby. The cpu fun keeps
spinning.
Depends on the flavor of standby. On some systems it is settable as to
how
far "down" it goes.

To switch it off will save significant power and I think it will probably
not shorten the life, and will quite likely extend it. When the components
are hot, they age faster (especially electromigration in the metal tracks
on ICs etc.) When not in use overnight, if you unplug the whole system
from the power and also disconnect the phone line then you will greatly
reduce the chance of the computer being damaged by lightning too. In some
locations, that could significantly increase the life expectancy of the PC.
You would also eliminate the chance that the computer could cause a fire to
start, not that this is very likely in the first place.
In most cases the PC will become obsolete before it wears out anyway,
whatever the effect of leaving it on or off, so you might as well save as
much power as you can by switching it off when it is unused for more than a
few hours.

de-spinning the HD is not usually noticeable. Spin-up is not always |
audible. The several seconds delay for a full spin up is. The biggest
savings come from shutting off the CRT (blanking, then stopping the
scanning) the next best savings come from de-clocking the CPU.

I hear mine shutting down and and have to wait for them to start back up,
yours probably do too if you have that feature enabled.

the parts that use most of the electricity are off.
