Windows 8: Disk Usage at 100%? Nothing Responds

Solution 1:

It took me WEEKS to find out a solution. Hope is the same for you:

When the disc is working at 100% and Windows barely responds, try to disable wifi via fn key (if you're using a laptop) and check if it gets better. If it does, I reccomend you uninstalling the Bluetooth/WLAND driver and try again.

I made a clean Windows 8 install after weeks trying to solve it. But it started again just after I install the driver, and solved when I uninstalled it. I wish I knew that before having to spend a entire day installing and configuring my laptop again.

Solution 2:

I had the same problem, and I did everything that the others suggested to fix it, but nothing worked.

Finally, my hard disk stopped spinning at 100% after I changed the power options and turned off the hard disk after more than 3 hours. Depending on how long your computer stays idle, you could try to make it 60 minutes.

My simple thought was that the hard disk spins because the computer has limited RAM. Even when there were huge files in the process list, it still worked. When the power option of the hard disk stopping before the page file jobs are done, there's a huge process queued up in the RAM. When the hard disk becomes active again, the hard disk has a lot of page file jobs to do.
