Keyboard repeating keys and headphones having humming noise on my new
Recently, I built a new pc and everything has been working fine except for the keyboard randomly spamming keys in random intervals after input and also the headset making a constant hum while plugged in. These problems weren't present on my previous pc.
(going more in-depth about the keyboard is that it works fine most of the time but sometimes it randomly repeats a key after input and will only stop after I input another key. If I don't interrupt it, it repeats indefinitely)
I plugged in my cousin's keyboard and the same issue still affected his keyboard so I know it isn't a problem with the keyboard itself. I've done constant searching, troubleshooting, reinstalling drivers, and even reinstalling Windows to no avail. No articles, videos, or forums on Google or youtube have helped.
We've been thinking maybe that it's a motherboard issue and are considering replacing it as a last resort.
If anybody has any advice, tips, feedback, or anything that would be helpful at this point, I would greatly appreciate it.
My keyboard is the RK 84 Royal Kludge RGB:
My headset is the Razer Kraken Ultimate:
