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?
You can easily use a boot stick with ubuntu and thats it. If you have a second pc, download the ubuntu iso and balena etcher and make a stick. It has live boot as default so you can use ubuntu on that machine without changing your harddrive. From there you can access the internet and you could download a malware scan for windows (i suppose) that can not be tricked since the malware is not installed on the ubuntu os. I hope this helps.
