No any drive found & CMOS Settings Wrong

[HLC]

I've finished my build, but when I boot it up, it first says, "Detect drives done, no any drive found".

Why? I have the hard disk connected by SATA connector and the CD/DVD drive connected by SATA connector, and both are connected to the power supply.

Then another screen comes up and says

"CMOS Settings Wrong
Press F1 to Run SETUP
Press F2 to load default values and continue"

It is an Asus P5K motherboard.

When I click F1 to enter setup, it has DVD RW on SATA1 listed, and the hard drive on SATA 2 listed, so why did it say "no any drive found"?

BTW I've already reset the CMOS.
