Hello, thank you in advance for helping.
I finished putting my new PC together a few days ago, but when I powered it on and got to a screen telling me to press F2 or DEL, they wouldn't register and I was stuck on that screen despite my keyboard having power.
I tried every single USB port, tried a second keyboard, removed the CMOS battery waited 10 minutes and reinserted it, and now even replaced the motherboard... but I'm still having the same exact issue. I'm starting to go crazy and considering just bringing my PC into a shop to have someone diagnose the problem.
One thing that might be noteworthy is how my keyboard only lights up if it's plugged in before turning the computer on. If I disconnect it and reconnect it, it won't have power. And if I plug it in after the computer is already on, it also won't have power. Everything plugged in gets power just fine, though. All fans run and LEDs work just fine, too.
Any advice or help will be much appreciated before I go ahead and bring it in for help. I have followed every step to a T.
