I have a less than 3-year-old Dell Studio laptop running Windows 7, Internet Explorer 9. I use the touch pad, not a mouse. Lately the scroll bar moves on its own and the cursor does, too. The cursor bounces all over the place. This is driving me crazy! "I've read some of the answers to this question but I either don't understand what they're talking about or my computer doesn't have the "category" they say to click on.

Have you tried upating the driver for the touchpad? This can be found on the Dell support page support.dell.com –  Nils Magne Lunde Jan 24 '13 at 7:48
    
It sounds like it could be a failing mouse connected to the USB port. Some laser mice wiggle around if they got confused about what they see (which happens at a certain distance from the surface), but they don't scroll around (unless the scroll wheel is not a mechanical wheel either). –  Jan Dvorak Jan 24 '13 at 8:49

I've found before that wireless interference from another wireless input device can be a cause of similar problems. Maybe you could look for other wireless input devices in range?
