My recommendation would be to run mbmon or something similar to  
monitor system temperature, etc.  I've not got a lot of experience  
yet with the AMD64 architecture, but the little I do seems to be  
prone to over heating.  Often, when I've had similar problems to  
those you describe, I can later attribute those reboots and crashes  
to system temperature.
