Bios

[titus12]

Will the Bios chip on the motherboard cause the computer to give off a
burned order? When I turn on the computer, it begins to smell like
something is burning and stop.

Thank you,
David

My vote would be the power supply. The transformer wires are coated in
lacquer and when then heat up give off a very distinct burning odor.
(distinct if you have had the chance to smell it before of course.)

Chips have to get pretty hot to smell. Dust in fans might, especially
if the fans are not running up to speed.

Look to the power supply or the CPU fan/chip assembly. A CPU can run hot
enough to melt a fan that is not running..

If it happens immediately after turning it on, it sounds more likely that it
is in the power supply, I'd think. (At least with the CPU fan/chip
assembly I think you would have a little bit of time, unless just the CPU
itself is fried, which seems less likely, and if the CPU were really fried,
it wouldn't even be able to boot up into BIOS.

It helps to mention the details of the computer, such as make
and model, or if it is home built, the motherboard make and model.

There is one chip which has a problem - the ICH5 from Intel. Every
once and a while, one of those will burn. But the computer would
not POST any more, if it did that.

The power supply could be at fault. Failures of power supplies
are fairly common (I've had two bad supplies in my collection
of computers here, and zero bad motherboards). But really,
you should take the side off the computer, and have a look around.
You might notice that something had fallen out of place,
a fan was stalled (no longer turning). A video card will
get pretty hot, if the fan on it stops turning.

There is no particular reason for a BIOS chip to burn. I have
heard of it happening, but for a good reason. Somebody put
the chip in backwards, into its socket, and the person who
posted the problem to USENET, noted "I see two glowing things
on the BIOS chip". Those were the power and ground legs,
burning off, because the chip had been inserted backwards,
and the BIOS chip was destroyed. It wasn't the poster's
fault either - the place he bought it from, put the chip
in backwards.

Based on your symptoms, you should also check that the CPU
fan it turning. Sometimes, a wire from the power supply
can fall down into the CPU fan blades, and stop it.
When the CPU overheats, it can shut off the power supply.

The power supply has internal protection features as well,
and it can also shut off if the internal temperature in the
power supply is too high.

Cut to the chase here. No more than any other chip on the motherboard. See
Mike's reply here for more likely suspect. In addition to that, the more
subsequent times you turn it on, the more likely the cause will burn itself
to oblivion.
