Sometimes when plugging in my headphones, my computer screen starts rapidly flickering with different colors. This has happened with more than one pair of headphones/earbuds, and never happens when I tap the headphone jack against the computer case first, which makes me think it is almost like the computer is being shocked a little bit. Here's a video of the monitor. Is this a problem with my graphics card, or something else entirely?

Thank you for your reply. I will try another monitor and post if it happens again, but I don't have another graphics card to try. My motherboard is a ASUS P8Z68-V LE. If this issue occurs with the monitor, I will try plugging into the back. Once again, thanks for the tips!
