If nothings working are you getting beep codes when you try to start the system? Refer to the system manual to translate what they mean.

Try resetting the BIOS settings to their defaults, and make sure all of your hardware ports are enabled. Is the hard drive viewable in the BIOS?

You may need to update your BIOS if a newer version is available.
