Laptops :: Installing on laptop problems

So, I can't get my little touch pad thing to work, and I can't figure out why! I can't even get it to correctly instal on the HD.

Please help!

Let me better explain myself - The touch pad does that thing where you move it and it goes straight to the bottom and you can only move it left or right, right? Right. Anyways, I hooked a PS2 mouse up but it still uses the touchpad instead of the mouse! How do I change it to use the mouse and not the touchpad?
