This past Sunday I tried turning on my computer, only to hear a loud buzzing sound. When computer reached the point where it would usually boot into Windows, the screen just filled with 1's and 0's. I thought the harddrive had crashed, and thus went out and bought a new Western Digital drive. Alas, after this new drive was installed, I got the same buzzing noise when I turned on the computer, again eminating from the front section of the computer. I now get the Boot Disk failure error. What could be causing this noise?
