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. > You could try memtest86+ for several hours. I will try this and the visual component inspection as soon as possible and see what I can find. > I'm not sure "blown capacitor" is the correct English term 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.
