Hello, the issue you describe is very often hardware specific, so giving 
as many information as possible will increase the possibility to "ring a 
bell" with someone on this list. The most common I have seen are bugs in 
some CPU sleep state, graphic driver that crash and put the graphic 
server in an irrecoverable state and lock up the GPU. Huge memory leak 
in a program can also lead to what you describe, if the kernel oom 
doesn't kick in or does but kills an essential part of the session.

Did you try to look into your system logs at a time right before the freeze?
