  • I'm guessing it's software problem

    I'd guess it's a hardware problem.

    Spinning hard drives? Are they close to failure?

    This sounds like an I/O issue that then buggers everything else until it unblocks. But for it to affect most things sounds like something fundamental like the hard drive, or SSD, etc.

    Ran SMART tools? Checked errors?

  • running off SSD so shouldn't be a disk spin problem

    everything here looks OK

    @graunch - i haven't looked extensively (cause the system freezes so I don't expect to see anything useful) but also because it happens when i'm browsing and when I'm playing games. Resource use doesn't seem to factor into it.

    @aggi - i haven't. My plan was to try and fix or rule out a hardware issue then fresh install of windows to see if that fixes it...

  • Which is your C drive?

  • running off SSD so shouldn't be a disk spin problem

    Lots of reasons SSDs can do this:

    • dead sectors and not enough space leading to blocking defrag
    • old firmware (known bugs)
    • generic Windows driver rather than correct driver
    • incorrect connector or device config for the connector
    • paging on an SSD without a lot of space

    Those just the top of my head.

    I/O is still the likely cause.
