    Suddenly my PC is constantly at 100% disk usage, running slower


    It started yesterday, it took an unusual time to boot up but when it finally did my PC was running very slow. At first I thought it was some kind of malware so I ran various scans and found nothing, everything was fine. I didn't do anything out of my usual routine, I just use my PC to work and now it's being very hard to do so

    Disk Usage at 100% with nothing running

    My PC is running Windows 10 with the latest updates but has suddenly become unusable with disk usage staying at 100% even with nothing running and just the same processes listed in Task Manager as before the problems
    started. I've tried a few suggestions found in online forums - disabling Windows Search and Superfetch, adjusting page file size, etc. but nothing has done the trick yet. I don't have any outside anti-virus software installed. I read about the potential MSI
    issue but don't have IDE ATA/ATAPI Controllers listed in the Device Manager. Finally, it seems to boot up normally and will have periods where the disk usage drops and it's usable but those moments are brief and it inevitably goes back up to 100% usage.
