Hey I just bought a new computer recently and having some problems. It was working fine and then I shut it down and then it came up the the error "REBOOT and select proper boot device". I wasent tampering with anything it just randomly came up with this message.

I went into Bios (v02.61) American Megatrends and the SATA 1 device was not detected. BIOS is not detecting my hard drive for some reason. It detetcs my DVD player in SATA 2 but every other SATA slot is empty. I tried to make sure the wires were in correctly and they were but that didnt solve my problem. I know the hard drive is spinning because I could hear it. There was also some message regarding express GATE but I dont know if thats part of this problem. IS there some setting in the BIOS to make the hard drive bootable?  I should also add that during start up before it never recongnized the hard drive but it booted up still.

My system specs:
Quad core Q6600
DDR2 memory 4 gigs
ASUS P5Q SE motherboard
Nvidia 9800 GT video card
Vista home PREMIUM 32 bit
Seagate 500GB hard drive
