I would try to get into the BIOS first by tapping Del. If you can, check the hard drive is registering. If you cannot get into the BIOS, it could be of misplaced components on the motherboard (eg. RAM, graphics card, modem). However, if you havent moved the pc at all, then it is likely that you will require a motherboard to be replaced, and the slight possibility of a power supply because of compatibility.
