Every so often, my Vista 64-bit operating system blue-screens within about three minutes of booting up. The blue-screen indicates
BAD_POOL_CALLER. Searching on the Internet indicates that this points to a bad driver or bad RAM. I have used http://www.driveragent.com/ to verify that I have the latest drivers for all of my hardware. I have used memtest86 to verify that my RAM is good. I am not overclocking my computer. Provided my computer survives the first five minutes after boot, it can run indefinitely without problem. It does not crash playing 3D games, running VMWare, running "burn-in" software.
The blue-screen does not happen often enough, perhaps one time in four, for me to simply try uninstalling various drivers to see what breaks. Having Windows "check for solutions" results in no additional information. What other steps can I take?
