static discharge perhaps in which case you might be screwed .. reseat everything .. make sure your heatsink on your CPU is secured/attached correctly .. try a different power supply. Unplug all peripherals from mother board and power and just fire up bare minimum to get into BIOS. If still no go, remove everything from case and place motherboard..etc on on non-conductive surface and plug in PSU and test components outside of case.

Generally, when a setup acts like your does, it's CPU overheating (heatsink popped off or the like) and thermal protection kicking in right away and shutting your system down to avoid damaging the CPU.. or your power supply went belly up
