How to fix problems with my pc after restoring?

I have a lenovo think pad and after I restored my pc to factory settings the speakers do not seem do be as loud and also my mouse pad only clicks on something if i click the very bottom left corner. Before I restored I could click pretty much anywhere on the left side and it would click. Anyone know anything that would help?

You should format your system.

Go to the Lenovo site. Download their system controller that allows you to update the drivers to the latest ones that Lenovo produce.
