    My build:
    Intel i5 2500K
    ASRock Z77 Pro4 mobo
    MSI GTX 970 8GB
    Memory (2 x 4 corsair vengeance)
    GX 750W 80+ bronze
    120gb Samsung SSD to run OS on
    1tb HDD 3tb HDD
    Windows 7

    Now, this has only just started happening today and I can't figure out why, but when I'm on the desktop with just music playing through Spotify as I usually do, I get random hitches every 3 minutes or so where the computer locks up and the audio stutters like crazy, this usually happens for around 2 seconds at a time

    What I've noticed: I use MSI afterburner to monitor this and CPU is at around 20% when idle and then when the stutter happens it jumps up to around 75% usage then falls back to 20% again Temperature doesn't change and stays at around 30 degrees

    What I've tried: Running computer in safe mode and running adwcleaner, rkill, tdsskiller, malware bytes full scan. Nothing has been found so I don't suspect a virus

    I'm not sure whether the stuttering was happening or not in safe mode because there was no sound and I wasn't moving the mouse around too much

    I've tried looking for the culprit in task manager but no applications seem too demanding

    Thank you for reading, I have no idea what this could be and I've been googling solutions all day but can't find any that work.

    Cpu at 20% at idle looks too high to me. Look at Task Manager's processes tab to see what's using the Cpu so much.
