I experienced not so the same issue. Mine was when it's from OFF and turned ON, it works properly like 10 sec or more then comes W7. But when ever i restart, it goes directly to BIOS and in the Overclocking tab. Also i cannot find the SSD in the BOOT tab/section.
Here is My thread incase you want the mahine specs:
