Hi Chris! What make and model? Has it always been this way? How old is the laptop?
Is it still under warranty? What does "I have tried every thing" consist of?
Are you using the touch pad? Have you tried to change the way your touch pad works? Try a wireless mouse.
I'd add that you should use a WIRED-MOUSE to test your laptop, not a wireless one. Also, you should go into Control-panel and disable your Touchpad for this test. If your laptop is working correctly, your touchpad should be able to be disabled, and ONLY work with a wired-mouse such as a usb mouse. If not, your laptop is defective and needs to be serviced and or replaced under factory warranty (1 year in most cases) as mentioned above.
