Check out the ASRock BIOS info sheet to make sure your version is the latest one. Sometimes the mobos sit in a warehouse for a while. Also, in the BIOS or your Hybrid Booster, check and make sure the optimal defaults are checked if you're not fine-tuning or OCing the computer. I don't know about too many mfrs., but after finding out that Abit had fail-safe as well as optimal defaults I checked my BIOS. Sure enough, the fail-safe defaults were selected which were a lot slower than the optimal defaults. Lastly, check in Program Files to make sure there's nothing from that mobo that needs manual activation and check Device Manager for any yellow warning signs.
