Will the Bios chip on the motherboard cause the computer to give off a

something is burning and stop.
Thank you,

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.
