I recently updgraded my machine and installed a new HD. The new HD is an 80 GB WD drive set as primary. I placed my old 40 GB drive as slave.
The machine is now making a low humming or buzzing sound. Its not continuous but a pulsating tone.
I am wondering what is causing this? I have a floppy drive, 2 CD-Rom Drives (one is a burner) and 2 HD off a 250 WATT power supply.
Could the power supply be making the noise? I diconnected the old drive and the noise stopped, but the drive never made the noise before.
