Just type CHKDSK.
Same problem here with high disk/ memory usage, especially when playing games. I've tried everything mentioned here and no luck. I'm on Windows 10 but had this problem previously on Windows 8.1 too.

It's been about 4 days since I've had this issue. My computer was running really slow, so I checked the Task Manager and saw that a "System" process was running under the name "ntoskrnl.exe". I thought it was a virus or a rootkit. I ran Windows Defender and nothing was detected. I just did a clean install of my operating system last night, and I'm checking my processes and the same issue is persisting.
I have an HP Pavilion m7 1015-dx.
If the problem is persisting like I think it is, can this be a hardware issue?

2016-09-30T22:54:41+00:00 For what it is worth, I tried all the other posts but what worked instantly for me was to stop the auto defrag "defragsvc".
It went from a constant 100% to 0% with nothing running. W 8.1. Now I will need to find out why defrag kept running for hours . ???
