Artifacts in Display

[Chantz]

Hey guys, I'm getting a lot of artifacts in my display when I stomp my foot on the ground, shaking the PC itself. I can't find out what is causing the issue. The artifacts themselves are patches of green hued lines. I have a hunch it's the GPU but I don't know how bumping the ground/computer desk/computer is causing this issue and how I can fix it. Thanks for reading.

What's the monitor? Make sure all video cables and the GPU are secured. Check video driver for updates. If those things don't help, your monitor may have some issues. I have seen this issue a lot with old boxy monitors.

It isn't the monitor, I have a fairly new aver monitor that's touch screen and was about $300. Hitting the monitor a little doesn't cause any artifacts to appear, it has something to do with the inside of the pc
