Hello Thomas,

I agree that it doesn't seem to be a Cycles bug. After examining this 
issue a bit more I have concluded that it is either a hardware issue 
with the card (or PSU) or a driver flaw present on both Windows and 
linux drivers. I only 'stress' the card with Cycles (and mostly on 
Linux) so I never had any issues before. Testing it using a couple of 
games on a fresh installation of Windows 7, however, showed a similar 
issue --- again, after exiting the game. So I have to conclude that it 
is either some driver issue or a problem with the card (or power 
supply), which is weird because it never happened before. I can see that 
there are several issues with GeForce 680s, and given that my card is 
factory overclocked makes it even more likely that something is flakey

I did not file a bug report as this was too vague a report to merit a 
bug report; I wanted to gauge the list to see whether there were other 
people with similar experiences; seeing that my machine crashed leaving 
me with no usable log to attach I thought filing bug report would be 
pointless. I hope I did not abuse your time and thank you for the 
information.

Best,

d.
