AutoCAD 2013

I currently am running the following system which is supposed to meet the minimum requirements for running AutoCAD 2013. Since installing this program, I have had trouble with AutoCAD. It keeps freezing and locking up, causing the AutoCAD to shut down. Is there something in my system that I can do to change how AutoCAD works on my computer, or do I need to purchase a new computer?
