NVIDIA GeForce4 MX 420 13.10

I have a Dell Dimdension 4550 I am trying to install Ubuntu 13.10 onto. I really would like tokick microsoft to the curb, but I can not figure this out for the life of me. The graphics card is a NVIDIA GeForce4 MX 420. When I do a fresh install it works, but the system is unbearingly slow. When i check the system monitor the CPu is pegging out t 95%-100% usage. When I check the hardwade it says there is a problem with compiz. I tried multiple sugeestion to get the latest drivers, but when I install and reboot I get a black screen and nothing haapens. Any suggestions I truly would appreciate it.
thanks in advance
