Sorry to make another one of these posts, but I've dug through at least a dozen other threads and no other solution has worked for me. My problem also seems to be slightly different.

Task Manager

As you can see, I'm using 100% of disk usage, which is causing my computer to be extremely slow, but it doesn't appear that any process is actually using the disk to an significant degree.

I have had this problem on and off for about a year now with a desktop gaming PC I've had for about two years. Storage is on a 2tb hard disk, with a 128gb ssd being used for SSD Caching. I've never figured out what makes the problem start or go away, the problem appears to happen when I boot the computer up every once in a while, I typically try and fail to fix it, and it eventually goes away, sometimes after a restart, sometimes not.

Some things I've tried:

1) Changing the paging file size as per this thread: https://answers.microsoft.com/en-us/windows/forum/windows_8-performance/windows-8-keeps-slows-down-to-100-disk-usage-and/cd787f8d-e7b4-4872-aecb-6f0cd15ad942

2) disabling superfetch and windows search

3) updating drivers (I think I've updated just about everything...)

3) restarting. Like a lot.

Thanks in advance.

After hours of continuing to dig through forums, I finally found the culprit. For some reason, my SSD caching was causing the problem. I have no idea why this would be, and why the problem would occur only sporadically, but disabling SSD caching appears to have had an immediate and dramatic effect.

This can cause high CPU use in windwos 8.1 and may effect your problem?

In Windows 8.1, when the user account name contains the word "user", intermittently you will find the process taskhost.exe keeps consuming high CPU percentage.
This is a problem in the component DFPCommon.dl in Windows 8.1.
To resolve the issue, do not create a user account contains the string "user" on the computer.
