From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

like others have said; the logs are your friends here; but you can also help narrow it down. the next time it happens, see if you can confirm how your system has frozen by doing these things:
if it's well and truly frozen, nothing will happen when you tap the caps lock key; as in your key led won't light up or you don't get any response at all.
if it does light up; then it might be your xwindows environment and you might be able to switch to a virtual terminal. most distributions have setup alt+ctrl+f1 through f7 to let you switch to one of them and some distros have setup alt+ctrl+backspace to restart your xwindows. if you're in this situation, then it's a safe bet that an application is causing your problem and you can narrow your focus on the logs there.
