Thank you for the response, Peter.

I haven't overclocked the computer but it is only a (quite old, now)
Acer Revo
with an Intel Atom 230 1.6 GHz CPU.

I will try this and the visual component inspection as soon as possible
and see
what I can find.

It certainly is the correct English term :)  I can't imagine how strange
it
must be to discuss such obscure things in a language other than one's
own.
I am ashamed to admit that, although I very much enjoy other languages,
I
could not even say "Hello, how are you" in Dutch.

All the best,

Wolf.
