Q: My MacBook trackpad has stopped working correctly and now my MacBook Pro is beginning to malfunction

yesterday my MacBook trackpad stopped working, after resetting my mac it began working again but was jumpy. Now a day later when I turn my laptop on the mouse works for a short while (maybe 4 minutes) and then begins to go jumpy again and then my screen moves to the right and my programmes begin to open and close randomly based on my trackpad movements.

I Have no idea what to do! I've tried installing updates to see if it was that but except for that i'm not that used to a Mac so I don't know! Any help appreciated!
