    When I start up my PC, everything runs smoothly. After a few hours however usually after I've stopped using it and then come back any game or 3D application I run stutters horribly and audio crackles with the stutters.

    I have tried;
    • Cleanly uninstalling and reinstalling all GPU drivers
    • Reinstalling Windows
    • Replacing PSU oddly this did actually cause the problem to somehow go away for a week, but it came back
    • Uninstalling and Reinstalling HD Audio Drivers

    So far the ONLY thing that makes the problem go away is either restarting my PC, or if I sleep it and wake it again the issue seems to clear up as well. But it always returns after a time.


    I have figured out that when this happening my DPC latency goes off the charts. Here are some screenshots of LatencyMon while it's happening;
