If it still has warranty left, take it back to store and pretend, that you dont know nothing about computers.
If not, then take that reflecting tape away from the bios chip and expose it to direct sunlight for few mins. Then put the tape back. UV light erases the flash memory, when tape is removed.
This should correct the problem. If it doesent, then you can buy new bios chip from the link already mentioned. BE SURE, THAT THE PROBLEM IS IN THE BIOS, NOT IN OTHER HARDWARE. Remove all cards from your MB and check EVERY jumper and wire.If power doesent turn on, then you have prolly shortcircuit or similar in the wiring.
