it sounds like you have multiple problems with your computer. microphone does not require any special drivers. your audio drivers do however need to be installed and working properly. also you must adjust mixer settings to be able to record.
if the cd drive is missing it could be many reasons:
1) cd drive is defective
2) bios is not detecting cd drive
3) data or power cable is loose for optical drive
4) drive letter is not assigned to it in disk manager
when did you first start having these problems? did you recently change any software or hardware?
