puke: hello. quite new to forums of any sort. but, having a bit of a prob: about four days ago, my pc has taken to not booting properly. the fans come on, and the LED lights for the cd-rom and CPU light up, but the the LED lights for the CPU stays orange. This is followed by a three-second whining (almost grinding) sound from inside the CPU. After which the LED light just stay orange. I can hear the fan and drive running, but there is nothing. the monitor doesn't even register that the pc has been turned on. i shut off the pc by pressing in the power button. i waited and tried again. same. so, powered down again and unplugged the pc. when i plugged in the pc just came to life and repeated the same thing (mind you, i haven't switched on yet). ive been all over my tech books and surfing the net for answers to this quandary, but i keep coming up with nothing. can anyone help?
