|Presume this is a laptop you are referring to since your question appears to be about a touchpad problem. ( A Mousepad is a pad you rest your mouse on )|
You have failed to tell us the brand or model of the machine or how much use it has had but a possible cause is wear & tear. There are two possible solutions. Get the touchpad replaced or use an external mouse.
"I am also having other problems with my computer as of late." Well if you would like assistance with these problems please post back with details. We aren't good at guessing.
