Make sure it has power (ejects). Check Device Manager in Safe Mode by pressing F8 during boot. Right click My Computer > Manage. Select Device Manager > View > Show Hidden Devices. Now delete all DVD/CD-ROMs and reboot. Windows will say "New Hardware Found" and install.

Try going into "control panel", find "device manager" and right click on it. In the list, find cd-dvd rom drivesand click on box at right side of line item. It should dop downand show your device. right click on it and you shoud see "enabe" or "disable". If it says enable, click on that.

If the CD-ROM drive is not being detected under the device manager, chances are that either the power/data cable is loose or the drive is dying. To check the cables, turn off the power, unplug the power cord, open the case and examine the two plugs behind the drive. Touch yourself to something metal first to discharge static electricity.
If it turns out the drive is dead, then luckily drives are usually very cheap to replace. Somewhere in the line of $15 usually.

Hi Friend,
Just remove the device with exclamation mark from device manager and restart your system. When your system restart again, automatically, it will detect the new hardware and install it properly.

Thanks,
Shiva

Wireless devices are not shown in device manager.

Before the BIOS can detect any piece of hardware the drivers must be loaded. The best place to get the most current drivers is the manufacturers website. If you received CD ROMs with your purchase there should be a driver disc there also. You could load that one first just get it started then go to the manuf website.
Another thing you can check is Device Manager. Device Manager will show all of your hardware. Find your CD ROM device in Device Manager, right click on it and update drivers. This should take are of your problems.

In the device manager, select the DVD ROM and UNINSTALL / REMOVE the device.  Restart Windows . . . did this work?  If not, boot into your CMOS and see if the drive is being detected by the motherboard... if yes, look further and make sure the settings for the drive are correct. Make sure that all IDE interfaces are enabled in the CMOS settings (both)

hmm...in device manager, are they both 'clean' meaning without any marks on them?

open control panel, system/device manager, and click on it to ensure it's no conflicts
