Burned out processor???

AMD Athlon XP 2900+
Abit KV7-V motherboard

For almost a year the computer had no problems then
suddenly it would shut down after 10 minutes. After
changing the power supply there was no change. The
motherboard had two weeks left on warranty so I got
that and it started shutting down after two minutes making
an ambulance siren sound from the beginning of the
problem.

Tried a new fan. Didn't Help.

I've taken everything out except the processor and fan.
When it boots it beeps, the screen shows text of booting
then beeps again, does nothing for a few seconds, beeps
again then shuts down blasting the siren sound. It only
runs for 15 seconds now.

Is there any hope for this processor?

Where is the best place to get another processor? Lowest Price?

I've been trying to get someone to test the processor but no one
has a motherboard this processor will work on.

Thanks From
Monkey Wrench

Sounds like it's rightly or wrongly detecting a cpu/system overheating
problem and shutting down. Have you checked the cpu cooler HS compound to
make sure it hasn't dried out, come off, whatever? Are you sure the cpu
cooler is mounted correctly? Have you tried defaulting the bios or
checking the shutdown params. cpu voltage/settings?

ebay, pricewatch?

Last week when I tried the new fan several times and it didn't
work I figured it was toast and posted my message. After reading
your reply I started to take the fan off and go through it all again
but decided to try it one more time, so turned it on and it works.

I had defaulted the BIOS and cleared the CMOS and all that stuff
many times and tried everything I could think of to make it work
and all this time it was the fan.

As for that Thermal Grease I threw that stuff away and the one
and only time I ever used it I followed the directions (It's not
rocket science) put it on and a couple of weeks later needed to
take out the processor for some reason and couldn't get the fan
off so I kept trying until I got so mad I pulled off the fan, CPU
and ZIFF socket all together and used a screw driver to pry it
apart. Everything still worked. That grease came with the new
fan that time and I heard a low of people swear it's good stuff
so I used it, but it was bonded like epoxy and I won't ever use
it again.

Thanks anyway for the advice.

That was on a AMD 500, a long time ago.

Am I understanding you properly? You don't use any sort of thermal
compound on your heatsink?

That is correct.
As I said it bonded like epoxy that time so I don't use it.

Do you think I should?

I am willing to listen to advice.

Thermal paste is a good thing to use. It helps avoid hot spots
on the surface being cooled (like if the two surfaces don't mate
well and have a big air gap).

The easiest processor, for thermal paste usage, is a processor with
a lid on it. That can take more abuse, than a bare silicon die (with
protective coating on the outside).

One way to remove a heatsink from a processor, is to heat up the
assembly before disassembly. If the computer is still in operating
condition, you can run Prime95 for 10 minutes, then shut down the
computer immediately, and attempt to remove the heatsink. Heating
up the compound a bit, even if it is luke warm, will make the paste
more pliable. If you apply a slight twisting motion to the heatsink,
that may help convince the paste to release and allow some air to
flow between the two surfaces (i.e. "break the vacuum").

If the computer won't run, then applying heat externally is another
option. But there are few devices at home, that have a precise
heating pattern, so everything in the way is going to get
heated. Which is not such a wise idea, if you use the wrong
type of heating appliance. For example, there are heat guns,
with low velocity airflow, used for melting stuff. One of
those could damage adjacent things in the computer. You
want a source of gentle heat, so the heatsink and surrounding
components don't get much hotter than they would in normal
use.

Pulling up immediately, once the clips are removed, is asking
for trouble. If you haven't made an attempt to break the seal
between heatsink and processor, attempting to just pull up on it,
will pull the CPU right out of the socket. So try a gentle
twisting motion first - that will help you to determine if
the paste has dried to the consistency of concrete or
not. Don't pull up on it, until you have some evidence that
it has released and things are mobile and ready to pull apart.

The reason paste products are thick, is to avoid "pumpout".
Every time the processor gets warm, that is an opportuntiy
for the paste to flow. In the past, there were products, where
the paste would all leave the area, and the joint between
heatsink and device would end up relatively dry. The current
generations of paste products are designed to reduce that
behavior. But at the expense, of making it more difficult to
break the seal between processor and heatsink.

That is one reason I like my tube of AS3. It is supposed
to be easier to remove than the current generation AS5.

Paul

You can't be serious can you? Without some thermal interface compound your
cpu will overheat. Don't like the stuff that gets like epoxy? Don't use
it, use something else. I've personally tested and use wheel bearing
grease. It won't dry out. Its easy to apply and remove, and it does as
good a job if not better than most commercial cpu thermal compounds. The
stuff I use is over 30 years old.

You need to use something, especially on older athlons with exposed
dies. The contact area between the die and heatsink is really small and
needs all the help it can get for good thermal tranfer to occur. Newer
cpus have a built in heat speader, but they can consume more power, too.
Basically every CPU since the P3 days NEEDS thermal compound of some sort.

OK, well I threw mine away and it's gone. I need to go to the big
city tomorrow. There is a computer store across from Comp USA
where I got the fan that probably has some.

Will Best Buy or Comp USA have any?
