Your PC has a 4090 and 13900f motherboard. It’s showing intermittent power issues—sometimes it turns on, sometimes it shuts down completely, but the power supply is still active. You noticed it lights up when you push the side panel, which suggests the GPU cable might be loose or damaged. When you accidentally insert the cable, it works briefly before cutting out again. Pressing the cable in seems to help temporarily. To fix this, check the GPU connection regularly, ensure the cables are secure, and consider testing with a different power supply if possible.

I would begin by testing a different cable (or multiple cables) to determine if it resolves the issue.
