get noisier and noisier.Help please
Any chance of a clue as to where these noises may be coming from. You could,if you so wished, remove the side from your PC, and see if you can hear or at least identify where the ever noisier sounds are coming from.
It could be a wayward hard-drive or fan either case or on top of your processor.
But it is tricky suggesting a solution to your problem without a little more detail as to where the problem is.
