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?
I had a similar issue on my pc with a 128gb samsung ssd. It would spike to 100% while doing nothing, and the pc would slow down to a crawl. I was able to temporarily fix the issue by deleting some files, because the drive was almost 100% filled up.
what eventually fixed the issue was a complete reformat of windows.
Some Microsoft reps told me it was some acpi error, and that turning off drive specific power management in control panel would fix it. I tried it, and it did work until I rebooted the pc.
anyways, if you’re facing some unexplainable problem with windows, I suggest you check out event viewer. Note down the date/time when the problem occurs, and try to find it in event viewer. If it’s a program thats not related to windows, check if it’s a virus / unused program and try to remove it.
If it’s related to windows, take as many screenshots and write a post on Microsofts own forum. The reps might be able to help you fix it.
Good luck!
