Lately my Windows disk usage has been "sky-rocketing" to 100% and then everything freezes up, nothing is responding. I can’t even open the menu from sliding my mouse to the top right corner and I can’t grab the top of my screen with the mouse. Kind of just seems like I'm looking at a picture.

I've already looked in Task Manager to see what’s causing it and I can't find anything. Everything seems calm but at the top it displays Disk: 100%.

It will stop after about 15 minutes and everything will be fine and back to normal, then when I get on the laptop later and boot it up again the problem persists.

Your picture would be (a lot) more useful if you sorted by Disk usage instead of by name, so that we could actually see things using the disk in the screen shot. :) Have you tried in Safe Mode? Have you done Disk Checks? Have you tried disabling start up programs? –  techie007 Sep 25 '13 at 15:06
    
The most common reason for a disk to be busy but not transferring data is read errors. That should show up on the S.M.A.R.T. values under reallocated or pending. Can you add those values to the post? (If you need help figuring out how to do that, look at these posts tagged smart here on Super User. –  Hennes Sep 25 '13 at 15:12

Seems to be an epidemic with Windows 8. See here and here for possible duplicates (and solutions). –  Rik Sep 25 '13 at 15:12
    
    
@Rik - In both of those examples it appears like a hardware not software problem. –  Ramhound Sep 25 '13 at 15:54

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.
