wow..this sounds like exactly the problem im having with win ME. I just installed a new cd-rom drive on my compaq 633mhz system and now i get an endless supply of those damn blue screens. It happens most often whenever i try and open my control panel..as an added benefit my speakers wont work at all. I cant even open my volume control panel without it crashing. for more info view my post about this called Please Help! at this forum.
