system

I have recently installed Natty on a new Toshiba Portege laptop. I find it extremely irritating that the system freezes frequently, about every other time I use the computer. Then the fan goes crazy and I have to force-shutdown. It seems to happen no matter what I do; I encountered this problem when using Firefox, LibreOffice, Adobe Reader - probably when using only terminals too, but I'm not certain. It may be fan-related, because the computer seems to get heated up compared compared to earlier, but I am not sure about that.

Any ideas why this could be happening?
