Laaaggggg

So I dunno why but for some reason my computer decided it'd start to lag the fuck out when I play online games. I recently got a driver update and it involved the internet so that may be it but I just don't know. I checked with my brother and he wasn't lagging at all. But this lag has cost me some stuff. I lost two games in League of Legends because I kept dying from lag and then when I went Mapling I died a couple of times which depletes your experience. It was working just fine yesterday though which is just making me think what the fuck happened. What could have happened besides the updates? I guess my laptop just has to adjust a little bit before it stops lagging but if it keeps lagging I'm not playing when I say I will just reset my computer. Half of what I use my computer for is to play videogames so if I lose that then I don't know why I'd just keep using. But then again I already activated the security program on my computer so if I reset it I need to buy a new security program also. Well I'll figure something out.
