Bluescreen everytime I click Infotool

I have a Benq 1650 dvd burner with BCHC firmware and TDK 12/10/32 cd burner. I have latest Nero installed but this also happens with Nero 6.6.1.4. Everytime I click on Infotool I get a blue screen immediately. The blue screen says driver irql not less or equal. I read somewhere that it might be due to a software conflict? I have Alcohol 120, dvd decrypter, imgburn, dvdshrink, ratdvd, clonedvd2, convertx2dvd, and anydvd all installed. I guess I could uninstall them all one by one and try to see which one is causing it but does anyone know which software is the likely suspect? Could it be Alcohol?
