Forgive my language but it's not only a possible cause for your problem but its genuinely an electrocution or fire hazard risk, having metal where it doesnt belong
You'll need to straighten any and all bent pieces of metal first
remove the motherboard
It goes from INSIDE the case, not from the outside
When installing motherboard screws, half install one at each corner and make sure the motherboards lined up properly with the IO shield before fully tightening any of them, then install the last screws
I'll find you a better picture to help explain this, but definitely make sure those metal tabs are bent where they're meant to be - they go *outside* the USB port 'towers' to help hold it still, but also for ground/earth connections
While you've got the motherboard out make sure you've got all the case mounting screws correctly installed - this motherboard only has 8 screw holes, you need to make sure you're not missing any standoffs, nor have extras where they could touch the motherboard. Incorrect setup there, even if its how the case arrived from the factory can result in motherboards sitting weirdly in the case, if they work at all. ATX, m-ATX and ITX cases all use different screw layouts, which is how this gets messed up.

Here's an example of my case, with the default 8 screw ATX layout and a letter guide on each screwhole for M A and I, for different board sizes
This has four unsused M screws, resulting in a loose board if used as-is
I've circled the two that would need to be installed (from the spares that came with the case, or the A ones moved up from below) in this example

These nubs are what latch onto the case to hold it in place.

You can see how the prongs sit on the outside of the ports - NEVER inside
This image is from before it's fully installed

This is what the rear ground ones look like, the image is taken before it's inside the PC so they're not aligned perfectly on the right side

How it looks lining it up to make sure it's oriented correctly

And heres pushing it in, from within the case
Diagonally opposite corners help, if the case or the IO shield is bent you can use the handle of a screwdriver to tap it into place
You can see the line of metal the bumps push against to hold in place

This is an example image of the USB ports being correct with those tabs all visibly used for grounding and support, and the ethernet tab being entirely unsafe
