MacBook Computer acting weird

[bronx549]

I have a 2010 Macbook and everything has been working fine. Over the last week the trackpad has basically not worked. Even when I attach a mouse, the size of the screen will increase, If I type in a document the dictionary will start looking up words. The screen goes back and forth to dashboard.
I've upgraded to Yosemite but the problems persist. Any thoughts? Thanks in advance.

You are accidentally right-clicking (mouse) and/or tapping it (trackpad). Set your trackpad preferences. Then connect your mouse, and set your mouse preferences.

I tried that. It works fine for the first 10 minutes that I use the computer, then it won't track properly.

Open up your MacBook and check the physical condition of your battery. When a battery begins to swell it causes the symptoms you described since the swelling pushes up on the trackpad. If you see any swelling at all, change the battery out, do not wait or damage may occur.
