Mouse is frozen on iMac using Mavericks.

My mouse is frozen in the left upper corner on my +/- 2009 that is running Mavericks. I have restarted several times and that did not fix the problem. Have started in Safe Mode, Recovery, original install disc but can't get past initial screen because mouse still does not work. In hopes that the mouse had died I purchased a new Trackpad today and it does not stay connected either. Is there some way to access utilities, etc. with the keyboard. Hope to be able to fix the issue myself as taking it to a certified repair shop is a 120+ mile round trip.

Suggestions? Point me in the right direction, please 😟
