Yeah definitively try that.  If you can do that, select boot in safe mode with networking.  Most manufacturers have driver & software downloads.  So go to your manufacturers website and look around.  If the software downloads don't work, then try safe mode again, and install a good virus protector such as zone alarms, or avg.  You may have a virus that isn't letting your computer run the keyboard or mouse.  If none of this works, maybe try new inputs for your computer.  Or a system reboot, cleaning your system completely out.
