Does the DVD power on light flash when you insert a DVD?
Is the Region Code set correctly in Device Manager? To get to Device Manager, click the Start button and then in the Search field, type: devmgmt.msc and then click the link to open Device Manager. Right click the DVD/CDROM drive, choose "Properties" and then click the "DVD Region" tab. You'll get a list of countries to choose from which will set the correct Region Code. Be aware that you can only change the Region Code a maximum five times. After that, it'll become set in stone and you won't be able to change it.
Is the DVD/CD you're trying to play compatible with your Region Code? For example, if you live in the UK, you can't play a DVD which was purchased in the USA because the region code isn't the same.
