So I installed Backtrack onto a disc, and it worked pretty well, it's just once in awhile it would randomly freeze when I tried to open up something. It's happened with every program that i've used, even the browser and terminal. So I decided to completely install Backtrack, and when I was on a live chat, I clicked on my browser and everything froze. My mouse wouldn't move, and i couldn't do anything. Do you guys have any suggestions on what I can do to prevent this?
