I recently was given an XPS 17 by a neighbour and i was able to boot from the disc drive, play music CDs, and install a new version of windows. But, as soon as i update the BIOS, the CD drive stops working... In windows, it shows up as a BD Drive but nothing... I put a disc in, it spins two times then stops. I don't know if i need a driver or what but I'm using windows 8 and before i was using windows 7. Any help would be appreciated
