Actually, a schematic will help here. However, you can try to clear the supply line as shown here. It usually works in noisy enviros like automobiles.

Hi Chris,
It is likely that the buzzer is generating a lot of spikes. If so it is possiable that the spikes will get onto the regulated supply through the internal clamping diodes in the PIC's inputs.
I would look at suppressing the buzzer input.
good luck!

To suppress the input, do you think I can just get a 100VDC cap and put it on the buzzer input or is it more complicated then that? The problem is that all of the inputs and the buzzer use the 74VDC for power. Maybe I should have used an optoisolator but I was trying not to add additional components. Any ideas?
