this sounds more like a hardware error if it's making funny clicking noises. Fortunately, replacing a DVD/RW drive is very easy and inexpensive for laptops.
There is usually just 1 screw that holds the DVD/RW drive in place on laptops, try to find that screw and pull out the DVD/RW drive.
Next, head over to eBay and pick out a new drive.
Insert it into the now-empty port, load the proper drivers (sometimes you don't have to) and you should be go to go.
Last I checked new DVD/RW drives were going for like $20-$30...not bad for an easy fix. You might even want to look into getting a Blu-Ray. Or just a plain DVD drive if you don't find yourself burning a lot of DVDs (most people don't)
Cheers.
