Thanks, to the first and last comment, the sound stop and it back to normal! and for the other two i not sure how to explain this but i'll try, sorry if this doesn't make sense but i didn't mean the sound that it makes when i press the keys but i meant that when i type the 'clicking" sound that's was coming from the pc it self ( i think it was pc thing and i think it made that 'clicking" sound because it over heated? i don't know i bad with computers)
