Try one stick of RAM at a time. Does your motherboard have video outputs?

Mine'll do that if I push the overclock too high, try resetting the BIOS back to default values, if that does n't work, reset the CMOS either by removing the motherboard battery or using the reset jumper.

Not working i think the problem its to the motherboard when i push the power button not starting, i push again reset buttons not starting again

You mean nothing happens when you push the power button?

Not even fans spin?

Take out everything apart CPU, power supply and motherboard. That means video card, RAM, hard drives, DVD drives, unplug monitor, keyboard, mouse. If it still doesn't start, then it's either case wiring that went wrong or the motherboard/power supply is dead.
