Dad finally installed my University expansion pack last week & I am very happy about that. Turns out that the problem might be something called a "Ribbon Cable" or something like that. It's the thing that reads the info being sent from the DVD drive to the rest of the computer. The way he figured it out is easy: He used an external DVD drive. It kinda looks like a DVD player but instead of calbes for the TV and a plug for power, there's just a plug thing-y.
