I had the same on my home PC a few weeks back. Hours of hair pulling to figure out what was wrong. Fixed it, then last week two "home-brew" number crunching machines at work (bought in from specialist builders and that moved to our centre with a research group) went the same way. The BIOS screens were vastly different from mobo to mobo though, making it hard to find exactly where to make the tweak - on mine it was under advanced boot settings, on the other two it was under security on one and advanced settings - key management on the other . Anyway my reputation as a miracle worker upheld.
