CPU upgrade sound problems

[Painternator]

Just upgraded my CPU from an i3-2120 to an i7 3770K, but now i am getting popping sounds through my headphones every second. I am using the integrated sound card.

I have uninstalled the audio drivers and reinstalled them and that didn't work.

Any suggestions on how to fix this?

Try updating the bios firmware to the latest version.
Did you verify the cpu was actually compatible with the motherbd?
