Sounds like hardware/bios to me? Maybe you didn't hit the ON button? (exaggeration made on purpose here).
Define "boot" better. Describe the failure with dumps and you'll be able to have a conversation in here. "Cannot boot" is not a descriptive/objective error message. Nobody can help you given that little information. The boot process is complex and has many many stages. Be specific or you get the responses you've been given here.
