Computer won't boot -- no error message

db.·.. >

well, if the bios
status screen doesn't
come up, then
this is an important
clue.

for example if
your motherboard
had no cmos battery,
then the bios
status screen
would not appear.

also, if the power
supply was failing
and could no longer
supply sufficient power
to the motherboard, then
you would get the signs
of a dead motherboard.

further, because the power
supply provides power
separately to the other
individual components
then you would see
the disk lights enabled
and the fans working.

perhaps there is only
enough power to power
the small components
like the led's and the fans.

double check your cmos
battery and the power
supply cabling to the
motherboard.

keep in mind that it
is not uncommon that
a power supply component
fails but the are relatively
inexpensive and easily replaced.

Now THAT is interesting. I didn't know that, and figured at least some
BIOS screen would come up. But since I haven't tried it, I don't know,
but I'm not so sure your statement is correct. One thing is sure: who
knows what BIOS settings would show up, and be, in such a case.

And that is a completely ambiguous "answer".

IF that part (just those specific output voltages and connections) of the
power supply are still working.

(Pretty unlikely, however).

I tried to check the CMOS battery, but my voltmeter was going funky, so I
ended up just replacing the battery. Also, while I did that, I went inside
the processor's cooling box and cleaned a lot of dust out of it. One of those
worked! My computer is working now.

glad you got it
functional again.

incidentally, if you
suspect that heating
might be a factor,
don't hesitate to keep
the side panel unmounted
and have a little desk
fan pointed at the unit
to provide more air flow.
