Go through the basic runthrough....
Go to the manufacturer's website and download the latest drivers
Remove the old w/ a Driver Remover
Install the new
Make sure that all connections inside the comptuer are secured and you have enough power coming from your power supply.
If all else fails, I'd RMA the drive if you can and buy a new one. Nowadays a DVD-RW drive is only $25 and with external hard drives being so cheap, no one really needs a Blu-Ray Writer. If you really need a Blu-Ray reader, you can get a decent one (8x) for $100.
BTW, Here's a Lite-On 24/12x DVD+/-RW w/ LightScribe for $23 w/ shipping. http://www.newegg.com/Product/Produc...82E16827106333
