There are specific fixes for 100% disk usage here:

Go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done: http://answers.microsoft.com/en-us/windows/wiki...

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most through way, then step 11 to check for damaged System Files.

Update your drivers from the PC's Support Downloads web page. Compare the latest drivers with the ones presently installed in Device Manager reached by right clicking the Start Menu. Make sure you have the latest BIOS, Chipset, Display (Video), Sound, USB3, Bluetooth, Network and all other drivers, or else download and install the latest now.

Could you give it a few days to settle down and make sure all the latest updates are installed? Also, check to make sure the Intel Rapid Storage Driver is installed.
