I've recently put together a new system and have not been able to get it to POST. At this point, every piece has been returned / replaced, so I'm thinking it's probably a stale BIOS on the MB. I've tried 2 different power supplies, and a dedicated video card as well.

ASRock H67M (B3)
Intel Pentium G620
G Skill Ripjaws 2x2GB DDR3 1333 (F3-10666CL8D-4GBRM) (which is on the captability list for the MB).
The MB has a sticker which says "H67M P1.80-15A". I'm assuming this is supposed to mean BIOS version P1.80. P1.40 is required to support this CPU. Are these boards shipping with older versions of the BIOS?
