Windows 8.1 Update 1 Disk Usage 100%

Solution 1:

So, truth be told, I did not have any luck with the previous solution I posted for this question. I tried a lot of other things, and the thing that conclusively worked for me was the combination of Disabling Hibernation and Turning Off the Pagefile. Try this and I guarantee that this will work if you're having the pagefile disk usage problem.

Solution 2:

My advice is, even if everything appears ok (LAN, WIFI, Audio, etc) still replace all the generic drivers with your laptop specific ones. Especially HDD controllers, Chipset, etc. Solved my problem.

Background:

I had the same problem on my Lenovo G770. My Lenovo shipped with Windows 7 but I upgraded to 8.1 and after installation all seemed to go well except for this HDD activity which froze the disk for 15 to 30 seconds every 15 to 20 minutes. Unrelated; I had an 'Unknown Device' in Device manager, which, as it turned out was connected with Lenovo Energy Management. So I installed that from the Lenovo website and my Unknown device disappeared. But that led me to thinking that Windows 8.1 had installed all my devices without me downloading any drivers from the Lenovo website. Long story short, it appear my HDD problem was connected with generic drivers that Windows 8.1 had installed.
