Motherboard does not recognize DVD or CD/RW devices.

Most likely a problem with the reader on the CD/DVD Drive.

Very easy to swap out a different CD/DVD Drive. Add the new device and see if that resolves the issue.

Well a quick check here says it should manage 4 x DVD write speeds:-

The only thing I can think of is that lens may have some dust on it, try a CD lens cleaning disk or a blast of air from an aerosol spray can.

After this, I'm afraid its down a replacement.

can you give me the name of the driver and i'll get you a site to download it

Make sure that your DVD drive detected and on the list in Device Manager as LG GH22NP20. If it already on the list, but still have the same problem, ask to the store where you bought that device for changing with the other one.

Try uninstalling the drivers in device manager, shut down, reboot and Windows should find both devices, it might ask for your windows disk to install drivers or search online to install them

Dear, you should put out the BIOS cell and put out the Ram from motherboard for 45 min and then keep or fix them same place where as they were working. Your computer read all devices that connected to your computer.

Try updating your drivers from www.hp.com

If the issue is that it won't play DVD movies only then you probably need to install or re-install the DVD player software that should have come with your computer. If you don't have it anymore, simply download from HP.

You can get the drivers from the internet via google or yahoo by typing the name and model of your dvd rw and get the drivers.
