Thanks Magic Alfa. Most of the time Gm sounds don't sound or show latency and other times they don't stop sounding after the keys are released. Do you mean I have a faulty 3.2 OS? How do I know that? Where do I get the good one then? Where is the dream chip located to check it?. Yes, I thought about adding more Ram but there are only two slots and this older DDR memories are more expensive than newer DDr2 and it would be better to upgrade all the motherboard then.
