I built my PC a few weeks ago, but a couple days ago I noticed in the event viewer this error , rt640x64 Realtek Gaming 2.5GbE Family Controller has a Hardware IO error, repeating infinitely. Even though the error is being reported nothing is actually messing up. If I reset the PC or disable the device it stops until I turn the PC off and on again. Sometimes the error doesn't even happen at all. Is this something I can just ignore or do I need to do something about it?
