Does the sound come from the front left corner? If so, it is a hard drive problem. The sounds you describe are typical of a hard drive, and if they get worse when opening up an application, that further confirms that.
Thanx for the reply. Sori for being away and didint look out in the forum. the sounds come from the left but cldnt confirm front or back cause the sounds come from the left. So far application runs well.but i didnt OFF my PB since a month ago and runs on power, cuz if i OFF it, i got hard time to ON it.It will OFF and give a message to press the start button. After running this sometimes then it stable and my machine can runs as usual, plus the rotating sound of course. Could it be the power supply problem too?
Wad hard disk should i replace? Care to share me some info?
Thanx in advance.
