Disk usage is always at 100%

Question

I have noticed that recently my computer has been slowing down. For example opening a folder would take around 20 seconds to load, moving a folder (from the same drive) would take a minute or so. When you move a folder it would stay at 0 bytes per second, then after 1 minute, it would speed up and move the folder.I can barely work with MS Word because it would hang. And using Chrome was hard because Chrome consumes a lot of memory as many of you know.

I figured out there was something wrong with my computer; it could be a virus or a program that is hogging all the memory. But it couldn't be a virus because I have an antivirus and I do not go to risky sites nor do I download. After checking my task manager, it seems that the disk usage is always at 95%~100%. When I sorted it by from biggest to smallest disk consumption, and found that the program that was consuming the biggest disk usage (Kaspersky) was only using 0.6 MB/s which is very small. All other program each amount to 0.1 MB/s. All other usage such as memory, CPU, and network are below 10%.

The problem is I'm running on an i7 2.40 GHz processor and an 8 GB ram so 0.6 MB/s should not be consuming 100% in disk usage. Furthermore, I have recently bought the laptop and so all parts are new. Anyway what I did was I reformatted the laptop (twice actually), and the problem still persists. When I upgraded it to Windows 10 (and inevitably reformatting the drive) the problem was still there.

TL;DR: Disk usage is always at 100%. Tried to reformat drive but problem still persisted.

Hard drives are rarely dead within a week, i guess you got very unlucky. Send the laptop back to the seller? Or buy a new harddrive :)
