I was using my computer the other day, came accross a virus and let my virus scanner wipe it out! I installed Nero 7 Ultra Edition the day before and was working on setting it up. I got tired of playing with Nero and decided to try to install a new game that I happened to have backed up to CD. As I went to mount the image with alcohol 120, I noticed the mount option was greyed out. I checked settings and they allocated 2 virtual scsi dvd-drives. I then checked My computer and to my amazement all my disc drives disappeared. IDE dvd burner, Virtual dvd drives, usb dvd drive. All other usb devices work as do the ide hard drives. I tried rebooting, uninstalling cdrom drivers and rebooting, uninstall ide & usb driver & rebooting,virus scanning...what else is there?????????
