Possible Short? Help!

[Sidikul]

I have a very interesting issue, eveything worked perfectly the other night until i unplugged my keyboard and turned off my computer. I plugged the keyboard back in and turned on the computer but I get no post, and my peripherals receive no power from the motherboard hub or front PC hub.

 

when I plug my graphics card into my motherboard, my motherboards USB ports completely stop working. There is no video out from the graphics cards, and no peripherals get power.

 

The system will post to the monitor if I plug in directly to the motherboard without graphics card installed.

 

When I unplug my graphics card, all peripherals and power work correctly. The system will also post.

 

I have tested my graphics card, Ram, and power supply with other systems. They all just work. And again, the system posts without the graphics card inserted.

 

Do you think this is some sort of short with the motherboard? The motherboard has a faulty light area that has the "VGA" light on.

I tested a 2080ti in the computer same issue as before so I think there's some short or something acting up. Sadly same issue trying the 2nd pcie slot on the Mobo.
