So i just recently moved all my pc components into a new case, powered it on and everything seems to be working fine. So i go to load up fortnite and it works fine i get no problems. But i come back to my PC later and i am getting a lot of what seems to be lag. I can run around in save the world fine but suddenly i my character will stand still and everything will freeze and then i will teleport back. At first i thought this was an issue with fortnite or with my hardware but i have tried playing other games (Rainbow six, CS-GO, Rocket league) and i am getting the same lag back. It is definitely a network issue as when i play rainbow 6 and my game freezes i get a network connection icon at the top of my screen. No idea what to do, i have checked windows updates, i have checked for new drivers. My PC is connected via Ethernet so i am thinking of getting a new Ethernet cable. Any ideas what might be happening, all my games are literally unplayable.
