Somethings go wrong and i dont know what. My computer will not boot up to the cmos setup screen let alone windows. when i switch the pc on the lights light up and then the hard drive whirls for a bit and then stops. The monitor never comes on and nothing on the screen comes on. The hard drive did make a few noises before my pc crashed. If my hard drive has gone, does thie mean i can't get to the cmos screen?
