Question I think something is wrong with my motherboard

[Gondawn]

I built my PC back in February, and everything was working great up until a couple of weeks ago. Recently, I started running into a bunch of strange issues that all seem to be connected to the motherboard. For example, my wireless headphones started picking up weird static in some USB ports and in others, the sound randomly cuts out for a few seconds and then comes back again. My keyboard has also started being weird - sometimes keys would get stuck (but not physically) until I press something else. On top of that, my internet (which is wired through a powerline adapter) now randomly disconnects and the only way to fix it is by unplugging and replugging the adapter.

All of this started happening at the same time, so I doubt it’s a coincidence. Since the problems all involve devices connected to the motherboard, I’m thinking there might be some kind of hardware issue going on — maybe with the board itself or power delivery. Has anyone run into something like this before or have any suggestions on how I can figure out what’s causing it?

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

What have you tried to remedy the anomalies you speak of? For starters, if you haven't, maybe reinstall all drivers necessary for your platform.

Try disconnecting the ethernet cable from the powerline adapter.
