So i recently built a new Gaming PC few weeks ago. The first week it ran perfectly all games with no lag spikes. Later on i have been getting huge lag spikes randomly in games such as CS GO, Team Fortress, WarFace and other shooter games. I have updated and newest drivers in my ASUS PCE-N15 Card and other components too. I am currently using WiFi, so i have been thinking if that is the problem, but it seems that PS4 works with no lag, with the same WiFi.. Please help! What's wrong with my computer? Thank you in advance.
