I went to Intel's site and used their upgrade tool and they indicated I needed their most recent update. They indicated it was 126.96.36.199 for Centro Wireless. I ran their update and the device manager says the version was 188.8.131.52, which I take to mean updated. After reboot their tool still says I have 184.108.40.206 despite the fact that device driver says its is 220.127.116.11. I did this exercise several times with same result. I don't know if it fixed the BSOD as the error was not predictable, but we'll see. Thank you..
