I feel asleep for an hour with my computer idling, when I come back the computer is unresponsive. In task manager I can see that the disk usage is 100%. I've restarted, updated and cleaned the drive. I have also disabled Window search and superfetch. Looking in SMART, Reallocated sectors: 2, Pending sector count: 208. The usage is back to normal currently, however it goes up to 100% just using chrome etc. Also, right clicking the desktop will freeze the computer, before it looks like the desktop refreshes and I'm back to where i was before right clicking. I don't really understand where to go from here and any help is appreciated.
