Hello A friend at work wanted me to look at his computer. He said the hard drive crashed so he bought a new one and it would not work. So I got the computer and opened it up and everything looked ok. When the power goes to the computer you can hear a little whisper from the power supply and that is all. No lights or chirps or anything. I thought maybe the power supply was gone so I went and got a 450 watt power supply (there was a 400 watt in the system). This produced the same result. It did nothing. It is an GFXCEL PC133 motherboard with 2 sticks of 128 MEG ram. The original hard drive was a 10 gig caviar and he replaced it with an 80 gig WD SATA hard drive. I think it is either the motherboard that is gone or it is the power off and on switch that is gone. Could it be something a little easier to fix ? He said the hard drive was making a lot of weird noises before everything stopped. Thanks for taking the time to read this.
