Hmmm i can't help you with updating the bios since i never have a Asrock MB. But, double check that you are download the correct bios for your MB model and check the manual only.
Anyway, on the bios changelog you can see that the 2.10 bios update added support for windows 8, and since you have the 2.70 one it should work correctly.
You can check the dcp latency of your machine, maybe is some kind of hardware that is throwing way to much exceptions.
Also, check the config of your bios and check whats your default graphic driver.
