Hi and Welcome!

could you please provide some information about the motherboard of your new computer and also about your DVD-RW drive?

As for the detecting of discs - could you please describe the problem more detailled?
Can you read plain data DVD discs (or browse a video DVD using a filemanager like Explorer)?
Are there any error indicators in Device Manager (assuming you are using Windows)?
