I was merely pointing out that you had a pair of statements that were contradictory of each other. If I had wanted to start a flame war, trust me, you would know it
Now, back to the subject on hand -
When my system crashed playing Guild Wars to the 8x6x4 desktop, The driver itself had failed. The video card was not disabled, but the driver itself had dumped and so I came back to Windows with a messed up desktop. Nothing short of rebooting the system would fix it. I finally got fed up with it, and loaded instead of my older drivers (I keep ALL of my Nvidia drivers, you never know when you need one to test something with). The odd crashing stopped, and I was able to play GW for hours on end without a single problem.
YMMV, of course. What fixes things for me may no necessarily fix things for you.
