Hi there, this could be several problems but more likely then not this is a hardware failure issue either with your motherboard or another component due to overheating. This can be hard to test obviously due to the fact you can no longer boot your computer up, but you can have a diagnostics check done by Data Doctors or another computer technical company to find out which component has failed and then make the necessary replacements.
Good Luck! Kevin
