    Your Bios believes that the cpu settings have been changed either by virtue of a new cpu or overclocking/underclocking. And it doesn't like it.

    edit: this could be due to a bad cmos battery, a blip in the psu output to the mobo and thus the cpu that made the bios think the cpu was undervolted/clocked, etc.

    I once had a bad case fan that dropped my 12v rail enough that I got occassional 'overclocking failed' alarms on boot.
