Your optical drive is not working. you need to replace it.

No all cds/dvd work in all cd/dvd drives. I suspect your drive cannot read that make of cd although anothers cd rom can. Try making a copy of the disk on someone elses pc and try that in yours and you will probably find it works. You could always copy the cd to a pen drive and install it on yours from that.

Hello
Head of to the Acer website.Put in your model and serial # of your laptop. Find and download the cd or dvd drivers and install them on your laptop.

Also have you done the windows updates? Usually this will solve the problem.

replace the laser

well if its new i would say return it, if not then i would suggest to use canned air and blow out the inside of it and try it again. if that don't work then i would recommend getting a new one.

In order to delete upper and lower filters you're going to have to edit the registry. The usual cautions apply. If the registry is not edited properly your whole system can crash.

1) Close all open programs
2) Click on Start, Run, and type REGEDIT and press Enter
3) Click on the plus signs (+) next to the following folders

* HKEY_LOCAL_MACHINE
* SYSTEM
* CurrentControlSet
* Control
* Class
* {4D36E965-E325-11CE-
BFC1-08002BE10318}

4) This folder is the DVD/CD-ROM Drive Class Description in the registry. Look for any of the following names in the right hand column.

* UpperFilters
* LowerFilters
* UpperFilters.bak
* LowerFilters.bak

5) If any of the above keys shown in step 4 are listed, right-click on them and choose Delete
6) After deleting the keys, close the Registry Editor
7) Reboot your computer
8) Open My Computer and check to see if your CD or DVD drives have returned. You may also want to open Device Manager and verify that the yellow exclamation and error code on the CD or DVD drive is gone

Right click on my computer icon then click on property then ->hardware ->device manager

then check there is any cd/ dvd drive showing in list.
If you can see your cd /dvd driver then uninstall it.
then restart computer.
But if you cant seen then you need to refix your cd dvd rom.
For that pull your cd drive from laptop but make sure there is 1 lock system near rom just press that lock and pull drive then refix it.

From the device manager, Right click on the drive and uninstall it. Then restart your computer. See if that helps.

If still not, then you can try this step.
