So some backstory: I got a new Cpu about a week ago, I upgraded from an i5 4670K to an i7 4790K, and everything was all good. I mainly play overwatch, and never noticed anything wrong with the performance. Today, out of nowhere, I started to just get lag spikes in game and wasn't sure why, my frames are locked at 70, they'd sometimes freeze for half a second and drop to 20-30 briefly. I'm running 2 x 4gb sticks. 8Gb of Ddr3. I've literally never had this issue before. Someone suggested updating my killer network card drivers, already have the newest drivers. Scanned for a virus with Anti-Malwarebytes, nothing. In my memory usage, it literally says the process using the most memory is chrome if its open. Right now I literally only have task manager and two tabs of chrome open and I'm at 90% ram usage. This literally just started today, I have no idea what to do at this point, I'm considering trying switching the ram sticks to the other two slots but I doubt that'll work. Is it possible that I have malware? I haven't installed or downloaded anything dodgey lately, so I'm just so confused how this just happened.
