Hard disk clicks when clicking links

Anyybody experienced the hard disk clicking everytime you clink on a link in a browser window?

I have Dell D500 latitude upgraded with a 100Gb Seagate momentum IDE hard disk running XP pro – I have all the latest updates.

The disk clicks every time that I clink on a link inside a browser window or select any button on a web page.

I have checked the DMA settings in device manager / IDE ATA/ATAPI/ for the primary IDE channel and it is set to Ultra DMA mode 5 with auto detection

Is it an Internet explorer setting thats causing this
