Another bit of voodoo I would add to Clemens' suggestions is to use an
eraser on the board edge connectors while you have the boards out. I have
seen this completely cure computer problems.

>>Dear Paul,
>>
>>there is definitely the age of these computers that could cause a problem.
>>The other "easy to fix" causes could be:
>>
>>- Dust, did you regularly clean the dustfilter behind the frontpanel of the
>>Aspect 3000?
>> or have massive amounts of dust accumulated around all the components.
>> Make sure the airflow through the computer is unobstructed.
>>
>>- Bad contacts, one of the "magical" procedures with Aspect 3000 boards
is to
>>pull them out of the computer and lay them flat on a surface with the
chips
>>on top. It is advisable, if available to
>> put an antistatic or conducting material underneath it. The you push
down all
>>the socketed IC's
>> down. Put your two thumbs on the chip and press firmly. If it is all the
way
>>down nothing should
>> happen, if it is not you will hear a slight noise when it goes in. Then
make
>>sure all dust caught
>> between the legs of all components is removed.
>>
>>- Power supply problems, your power supply could intermittently drop out.
>>
>>I hope it's one of the above, that can easily be fixed.
