Is my PC looking for a RAID???

[Tumble]

When it boots (only started happening this morning) it gets past the drive detection gubbins, where it sees both HDDs fine, and instead of loading windows normally, it says "checking IDE drives" When it's finsihed doing that it comes up with "No array defined" and asks me if I want to start something called the "fastbuild" utility.... the thing boots in safe mode, but not a sausage normally dunno what I've done out of the ordinary to it... i'd be inclined to say nothing.... but.. help?!?!

go into your bios, in the advanced settings there is probably a setting for enabling onboard raid. disable it.
