The ! mark is telling you that the computer knows you have a CD-ROM drive it just does not know how to talk to the device aka (driver)
\015\012
\015\012If you have the disk the laptop came with it should have the drivers for the CD-ROM. If you don't you will need to go online and type in the model of you CD-ROM and the driver needed for it. Once you download the driver and reboot your laptop when you check the device manager the ! mark should go away.
\015\012
\015\012Sometimes you can just right click on the device with the ! mark and say update driver and it might find the driver automatically for you.
