OS: Windows 7
CPU: Intel i5 4670k

For the past week, every time I try and play a game that isn't League of Legends the framerate inevitably begins to stutter. Occasionally this will happen while watching movies as well. I should note that this happens regardless of the game's graphical settings. It happens most often in cutscenes or while playing any racing game (tried Trackmania and Need for Speed: Shift 2.)

I tried updating the graphics driver, hoping that it was just a case of the early 770 drivers being crap, but it made no difference. I'm currently running the 331.4 beta drivers.

According to GPU-Z, my graphics card is not under significant load while this is happening. Both my CPU and GPU are rarely under more than a 50% load in most of the games I've tried. I can't think of anything else to check.

The GPU was 55 C at its hottest while testing in Mass Effect 3. CPU and other components never got above 40 C.

I ran it for an hour. CPU reached 100% easily, temperatures stayed within acceptable ranges, everything performed as expected. No errors, no significant fluctuations.
