I7 4790K, ASUS Z97 K, GTX 970, Windows 10 on an SSD. Ever since building the PC around 5 years ago I've had the problem of never being able to upload anything, anywhere on the internet. I can upload small files on to google drive, but cannot upload images/ files on to the web, discord, games and more. I also constantly get booted off of live games such as Fortnite as I "can't connect to their servers". I cannot connect to Warzone servers period meaning I can't play at all. This entire problem is linked and is quite obviously a connection problem, however, I can't put my finger on what has caused it. I've just worked around the problem for all these years but recently have needed a PC upgrade and so thought if perhaps I find out if the issue is hardware I can purchase a new part. I suspect that my motherboard network piece, or whatever it's called, is damaged/faulty. I've tried different ethernet cables and have replaced my router and provider a few times over the years and still no resolve. If anybody can provide any insight into what they think it might be I'll be heavily appreciative.
