So I just built my PC like a week ago and finally got windows 10 installed, I've installed all my mb and gpu drivers too, the problem is that everytime I try to play games such as csgo fortnite and splitgate, when I ready up I get sent to loading screen then back to the lobby, I installed my games on a hdd and windows on SSD, I installed all gpu drivers and made sure my RAM was running at it's rated speed, everything seems fine, I've uninstalled and reinstalled my games over and over again yet still the same problem I checked for windows updates, still the same problem, I turned off my PC for about an hour and still the same problem, I did a factory reset but kept all my files and reinstalled the gpu drivers and I FINALLY got to play fortnite with a friend... For like 30 mins, everything was fine until we switched game modes and tried to play duos, my screen froze and I couldn't hear my friend and then back to the lobby, I also tried repairing the easy anti cheat thing but that did nothing and made kinda worse where I couldn't even open the game anymore, I dont wanna do another reset cause it's only gonna work for 30 mins I don't know the problem but here's one thing, my PC says I have no network connection but I'm browsing the internet right now🤔 I'm gonna restart my router tommorow(today) cuz it's late and I'm really tired but I hope anyone has any other solutions, but here is my PC build
