A little acceleration

[Volker Pittlik]

I had to buy new parts for my computer because the old motherboard cooked itself. The old processor was fast enough for everything I did. Well, the new one is a bit faster.

That's unfair where is my new beast??

That's unfair...

The speed is a cold comfort. Really the old computer and even the dual bord with the 433 processors were fast enough!

This was the second board which look like this after a while:



Before I studied I worked as a TV technician. Decades ago capacitors had an average life span of 30 years. You surely have an old radio or TV somewhere which is still running well. If the things get broken the whole computer does not work anymore.

These parts cost only a few cents usually. If one wants some which cook themself after a certain time the price is possibly a bit higher. Ths was the second time this happend to me. I don't believe it's just coincidence.

However, the new system is very good. It's also very quiet. I didn't install Windows at all (and have no plans to do so) .

...Great machine, was it running as SMP?

Yes.

... Did you try to repair the board (replacing the capacitor) before getting the new one?...

No, as far as I know it is not so easy to replace parts on a motherboard. A standard soldering iron (as I have) makes to much heat also it is easy to cause a short-cicuit because the conducting paths are very close together.

This is the damage which is visible. It started all with strange buzzing noises after after booting the machine (as long as it didn't reach its normal temperature). Then one harddrive didn't work, follwed by a CD writer. Five minutes after I finished a data backup the keyboard wasn't recognised anymore.

Even if the repair were succesful who knows what was broken next. I spend a bit more money for a good and quiet power supply now and choose the "slowest" Core 2 Duo. If I don't run a chess engine the hardisk is the loudest part of the computer!

hi volker,
a good repair shop should be able to replace that cap,
plus i'd replace all of the same color/manufactuer for
about 60 dollars american.
if you were here i could do it for you if you just paid for the parts.
i'm here and your there regards,
mike

Maybe I do that, but now I found out that the harddisk which has been indicated as broken still works fine. I put it in such an external case and now I have a pretty nice additional storage.

I think I'm going to disassemble the old board and sell the RAM and processor at eBay. Maybe I get 20 $ or so .

Hi Volker,

If you were to replace the motherboard then you would have a machine that you could run some long term learning experiments with!

I thought about it. Not for an experiment but just because I'm stingy.

If someone has to invest money in ancient technology to prove a theory, then it could be be something wrong with the theory .

However, today I got the last part of the new computer: a fan (arctic-cooling Freezer 7 Pro). Now the harddisk is really a loudest part of the machine even when an engine match with ponder on is running!

After 30 minutes of a cpu load of 100% the temperature is below 50° Celsius (122° Fahrenheit).

I can't remember that I had such a cool and quiet box before.
