The bios logs are usually found when you first boot up and hit F2 or 
Del.  One of the selections says something like log or logs.  I'm not 
sure where to find it on your board.  But things like overheat 
alarms/alerts are posted to it.  Not ALL bios' seem to have it, but most 
of the new ones do.

Do you have any peripherals connected to it?  I had a similiar problem 
on a Supermicro board, but it turned out to be my backup software.  It 
would run fine for about a week then just die.  I stopped the backup 
software and everything was fine.

It's a shotgun approach, but you might try shutting down services until 
you get to the one that's causing the issue.

VIA actually monitors the forum from time to time and I have had VIA 
employees respond to my questions.  That's more than I can say for there 
phone support :-)

Sounds definately like a kernel interfacing with some hardware issue.

Is the BIOS up to date?
