Just put together a new PC with a 3900X and X570 board....was loading up Modern Warfare 2019 when all of a sudden I lose internet connection. When it comes back...my download speed is about 11 MBs versus the over 100 I was getting before. Definitely seems like it could be hardware related but I wouldn't have the first clue where to look....CPU temps, while hotter then my 2600x....are still passable but maybe the mobo itself could be overheating?
