As the title says, I have 2-5 seconds of lag every 30 seconds to 1 minutes of playing games. My fps drops extremely low and I lose control of what I am doing. My computer generally runs 100+ fps and the "registered fps" says it is 30 when the lag occurs, though it doesn't feel like that much (this is while playing League of Legends). This problem occurs in SC2, LoL, and D3. I have put task manager on my 2nd monitor and when the lag occurs there is a significant drop in the cpu usage for the entirety of the lag. I have run Spy Bot scans and nothing has fixed it. I am using Windows 8.
