that is on your harddrive side, is your harddrive constantly accessing (your haarddrive access light should be constantly on, if its constantly accessing)???? have you tried reformating your laptop's OS??? what is your laptop spec, i.e. T or R model, CPU??, operating system, ram and harddrive size??? it could be a harddrive problem, you may need to get the service to get it looked at, otherwise your laptop's longevity would suffer....
