I am using windows 8.1 with the 2.40 bios. I had flashed 2.41 and 2.90 bios but they did not boot so i reverted back to 2.40 which may be the cause of my problem?

There is no red light on my Optical cable, it does work elsewhere. I have got the latest realtek drivers installed also i have used the driver that is reccomended on the asrock page.


Please help me =) is there any bootable cd's or there abouts that i can use to help my self?
