blowing out the dust, use a cdrom cleaner tool, replacing it with a new drive. Other than the laser and some electronice, they are pretty much the same piece of plastic as a 20 buck read only drive, subject to failure for a number of reasons. Which is one reason you can buy a new name brand burner for 40 bucks. Also check the data cable, still firmly plugged in? Did it go bad?
If your device manager sees it correctly, then it is not a driver issue.
