There you will find updates for your bios and the owners manual for your hardware.
Your first best bet is to reset your CMOS settings back to factory default (you did write down your HDD settings... right?).
Re-establish you harddrive settings ( your starting from scratch here ) and reboot.
This is a basic problem that should be easily corrected.
If, after reading the manual AND, making sure ALL updates have been applied you still can't get things to work, try reinstalling. If that fails, you may have a warranty issue.
