Computer completely locks up. Have to restart.

I recently installed ubuntu studio 12.04 64 bit on my new computer. Frequently it will completely lock up to where I will have to restart the computer. It won't even turn the caps lock on or off or let me type open the terminal. It will happen in such random instances that I don't know what is triggering it.

Here is my specs for my laptop in case that helps.

I don't know if this makes a difference, but it is dual booting windows 7 pro and ubuntu studio 12.04 64bit
