As you can see on the screenshot. Task Manager is saying that the Active Time of my NVM.e system drive has a lot of peaks that start to happen after a few minutes of using the PC and they won't go away unless I restart. I have tried so many things that I gave up and formatted the whole drive and reinstalled Windows from scratch. I have also tried the chkdsk command and this problem won't go away. This started to happen just a few days ago, out of the blue. The whole system freezes at every peak you see on the screenshot and the main tab of Task Manager reports the Disk Usage as being ~1%, so there is no process using the disk. Resource Monitor is also reporting the same thing.
Edit: I have narrowed down the problem to a insanely high Response Time on Resource Monitor (up to 2000ms). It is usually the “System” process that is having this high Response Time. Any way of fixing or at least knowing the root cause of this?
Hmmm interesting.
I guess you could try to install hwinfo, and check the drive health for that nvme drive. Also check if there are any other errors reported there.
You could also try to boot your pc in a live install of Ubuntu, or windows2go, and check if the weird drive activity persists.
And if it continues, I might suggest resetting your bios. I've heard these kinds of issues can occur with sata drives, but it might also happen with nvme.
Do note that before you reset the bios, you should set your current settings as a bios profile, so you could revert back to it if anything goes wrong.
If nothing works, I guess check what other users recommend, and if that doesn't work, try to get it replaced under warranty.
As always good luck!
