My computer is personally constructed with a XION tower box, an MSI MS-7578 motherboard and AMD Phenom !! X4 955 Processor, 23200 mhz. It has 8 GB of DDR3 ram, with a WD 1 GB HD. BIOS version is American Megatrends Inc. V1.6, 12/24/2010. I am using an Ultra 650 watt ATX power supply. I have Windows 7-64 bit OS installed. I have a Sony DRU-830A ATYA DVD-RW and an ASUS BW-12B1ST BD-RE drive. The Sony works fine but the ASUS will not format or burn any discs, CD, DVD or BD (RW or R). I need some help figuring out is the Optical drive is bad or I need different drivers and ASUS has been no help at all.
