One of Microsoft's suggestions: right-click your desktop and click "Properties" (to open the "Display" Properties panel, you can also get there through Start-Settings-Control Panel-Display). Go to "Settings" and then click the button "Advanced". Then, choose "Troubleshooting" and lower the "Hardware Acceleration" slider.
Did you actually get the configtool to work with disabled acceleration? I know if I mess with this stuff at all, it first k/o's my new nVidia driver (I just upgraded from an ATI Radeon), then the <img src="/ubbthreads/images/graemlins/beyond.gif" alt="" /> configtool failed with a "Can't read configuration file" error popup.
In any case, the crashes I've had in the past are still there, even with the new video card. However, when I get the bluescreen every so often, it's a different error: DRIVER_IRQL_NOT_LESS_OR_EQUAL. The only other thing that seems to be common is that a lot of people reporting these errors seem to be using ASUS motherboards.
EDIT: I see that you can go back about 2 notches in disabling acceleration. You can disable advanced drawing routines, but I don't know if this is really the real cause of the crashes, or if it will help any. I'll do some more testing and see if it helps or not, if it does, I'll post whether it fixes anything. I know that some people also changed their harddrives to run at PIO mode by disabling DMA.
