Sometimes while just running my computer will get 100% lag spikes. Where the CPU will top out at 100% and then lock up my computer for about 3 seconds and then be fine for 3 seconds then lock it up for another 3 continously. It goes from hovering around 0% an 4% usage (from mouse movement) to 100%. I just jumps, lags, then goes back down. While the computer is idle.
