hi all, after sorting all sort of problems of virus/trojans now i got another problem. my cd rom is not listed in my computer which means that iam not able to use it. It opens and closes but do not works. i am using dell system with 512 ram and xp home and pro both installed on same partition. Can this cause any conflicts. It is not shown in device manager. my device manager shows yellow mark against usb controller. please help. thanks

Obvious first: did you check power- and IDEcables (both ends on the IDE)?

Maybe something here- Restore Missing CD or DVD Drive http://www.theeldergeek.com/restore_missing_cd_or_dvd_drive.htm

Have you just installed one of the OS? Win XP or Win XP Home? Have you been changing hardware in your computer? Example the cdrom's. When you turn your computer on is the drive listed in your bios setup? Can you get to the BIOS setting and check and see if it is there? Is the drive listed in either Win XP Pro or Win XP Home? Or neither? Have you tried unplugging the data cable on both ends then replugging them? If you put in a cd does Win Xp respond with what to do with it?

thanks, i have checked the power. Maybe i have messed up somewhere in registry as i cant find what the link provided by chuck2 says

thanks, i corrupted my computer with virus on xp home so i installed xp pro (unknowingly). my cd rom was working fine for few days and i did manage to clear my pc from all the virus but the cdrom has vanished. i did not change any hardware but in the process of cleaning the virus and worms i may have messed some registry (i am not sure abt that).I do not have access to bios cos of password. I want to remove xp pro once i get cd rom working. if i put any cd in drive it do not do anything as it is not installed. thanks
