I just put together my new PC and connected everything correctly, but I'm running into an issue. My keyboard doesn't stay on when I plug it into any of the USB ports; it turns on briefly and then shuts off. I know the keyboard is fine because it works on my laptop. I'm starting to think there might be a problem with the voltage to the USB ports. Here's the build I used: https://pcpartpicker.com/list/nV4BQd

It sounds like a connection issue. Have you checked the USB header cables inside your PC? Sometimes they can get loose or not be connected correctly. Give them a look and make sure everything is plugged in securely.
Also, double-check that you've connected the USB headers correctly on your motherboard. If you have a USB 3.0 header, make sure it is properly seated. If it's a mix of USB 1.0 and 3.0, that could be part of the issue too. Just ensure nothing is mismatched.
