DVD/CD-ROM driver not working

i installed windows 7 and realized my dvd/cd-rom drive isn't being found

i went in device manager and it has that yellow icon next to it.

also i can't seem to find the driver anywhere on the net, it's so strange. i searched for an hour and couldn't find a driver for a cd-rom drive

i can't even find its brand

but my computer is a: Acer Aspire e380

i went to their website and they don't even have a driver download for a cd-rom drive

anyone know what i should do?

thanks

It's valid for XP, Vista and 7.

How did you install W7 if your drive wasn`t being found. CD roms and hard drives are detected by the Bios , make sure it`s being seen there 1st.
