Vista can't load DVDROMs
 

I have VISTA¡¡RTM and it worked well. However, it could not load the driver
for my DVDROM and DVDRW now, even the virtual CD-ROM(Daemon tools). I
uninstalled Daemon Tools, and the DVDROMS I have, then restarted the system,
but still failed. However, I switch to XP system, they all work well.

I have a sound card, modem, and a TV tuner on my PCI slots. I wonder why it
is all right in XP but not in Vista. How to fix it? Thanks, and merry x'mas!
