Recently I've noticed that my laptop was having 100% hard disk activity even though it's at idle. I went to my university's tech store for help, they aren't able to fully solve it either.
If I remember correctly, we tried:
1. Disable superfetch.
2. Increase virtual memory.
3. Disabled automatic windows updates.
4. Disabled scheduled hard disk defrag/optimizing.
5. Clean boot.
6. Disabled BITS
Before this, it was constantly at a 100% without ever going down. After this, it's able to go down to around 10%, sometimes even 0%. But whenever I open some program, something as simple as Chrome, it spikes to a 100%. And after certain tasks, it remains at a 100% without ever going down. It would only go down if I restart a few times.
Also, it would take a few minutes after startup for the percentage to go down.
Ps. Even on clean boot, it would spike to 100% too.
My laptop: i7, 16gb Ram, 1Tb hard disk, Windows 8.1, non-SLI.
Hope to get some help! It's really torturous to have that lag.
