[ILUG] Odd crashes

[Kevin Philp]

I have one user on my network whose computer routinely freezes (about 
once a day) - usually when using the mouse to scroll on a document. All 
the other users have exactly the same software (Ubuntu Karmic clients 
all connected to a Debian server which shares the home files via NFS. 
The computer will run for hours - and then just freeze, its doesn't 
recover either - when it goes its 100% non responsive. All the other 
users/computers are fine.

I have replaced the cooling fans, replaced the memory (which failed 
memtest) and replaced the mouse. Any ideas? I am wondering if there is 
something wonky in her configuration.

Kevin.
