CPU Problem??

Archived from groups: microsoft.public.windowsxp.hardware (More info?)

A power surge destroyed your old mobo/CPU, but you didn't
replace the power supply too.

If you had a power surge everything inside the computer
could have been damaged, But the power supply would have
had to fail in part to allow that surge.

Does the clunking sound indicate a mechanical problem?
Certainly does, clunks come from movement and the only
things that move inside the computer are hard drives. Your
CD/DVD only turn when in use.

he's right on you should definately replace the power supply but as far as the rest......

an electrical device can "clunk" without moving parts, temperature state changes can cause audible noise in any object


also your power supply unless extremely cheap has a moving part, the fan

defiantely replace the power supply

if still clunks,

go with a new cd rom

still clunks

try a new hard drive

if still clunking after that try new cpu heatsink/fan

In my defense, the wiper arm of the hard drive is likely to
clunk if it hits the stop hard, a fan is more likely to make
a different sound, either a bearing whine or a buzz as the
blades hit something.

And you are right that temperature changes can be heard as
parts expand and contract, I remember fondly listening to
the roof creak with every 5 degree temp drop below zero F.

From information as provided, only wild speculation can be
provided. For example, what type of surge was it? Examples
from what else was damaged by the surge would help define that
necessary information. Is nothing else damaged? Then it was
no surge. Surges occur typically once every eight years. And
most are too small to overwhelm existing protection inside
that power supply.

Second, power supplies (if not bought on price) contain
overvoltage protection that, essentially, separates computer
components from power supply. Surges most often bypass supply
to damage electronics; don't damage the supply. But those
'power supplies bought on price' can fail internally (not from
surges). The failure can then take out the rest of the
machine because it was bought on price - missing essential
functions.

If your machine boots and displays a message on screen, then
the processor is just fine. Processor is not a reason for
klunking.

First collect some facts. Is the power supply and other
parts of that subsystem working properly? First data taken
are DC voltages using a 3.5 digit multimeter. In your case,
voltages on the red, orange, yellow, and gray wires (from
power supply) are important numerical facts. Only with
numerical facts can one respond with something more than
speculation. Get the meter that is today so standard as to be
sold even in Sears, Radio Shack, Home Depot, and Lowes.
