    System Drive suddenly going nuts at 100%

    I assume that might be the indexing service but i took some screenshots

    You can check to see if the Indexer is actually working on Indexing data:

    Search for, and open: Indexing Options
    At the top of the window, see if the image on the left with the magnifier is animated, and see if "### items indexed"'s number is increasing. If so, then yes the Indexer could be doing this. Wait a while (like a day) and re-check the Indexer again. See if that number stopped increasing, and see if your CPU isn't working so hard anymore.

    Use the Resource Monitor to check what might be happening. When you see something stand out you can filter the listings by just that process.

    You can also check your memory usage and see what is using 80% of your memory.

    Of course, the last update caused my Drive to run very heavy for a while when it was checking or replacing installed components.

    Hi, thanks for the helpful screenshots.
    1. Windows search is designed to back off (stop working) very quickly if there is other activity on your PC. Thus if all is well, you should not be aware of it.
    2. Considering servicehost.exe, you can find out more: e.g.
    How to Fix Svchost.exe High CPU Usage

    I would also suggest as a very basic, elementary check you do this:
    From an admin command prompt
    [Windows key + X, click command prompt (admin)]
    chkdsk C: /F
    Your PC will need to restart.
    Make sure the result is clear or fixed- else do not proceed.
    Post back the result, which you can get after a restart as follows:
    How do I see the results of a CHKDSK that ran on boot? - Ask Leo!

    ** The actual data transfer rates you are seeing seem low.
    You can check further with e.g. Crystal DiskMark (free). Here's mine for my SSHD.

    Also check your disk with Crystal Diskinfo (SMART params).
