I am 99.99999% sure that this is not a chimera bug.  This is most likely a 
graphics driver bug, but it could also be a hardware bug or a BIOS bug. 
So you should first update the graphics driver.  There is also a newer 
BIOS, A05, that "addresses some NMI and blue screen issues seen by some 
customers using intensive 3D applications and games."  And please update 
your chimera as well to 1.2470.
