Random high disk usage on SSD

[Apekatt]

So recently, I have noticed a problem. For reasons unkown, my ssd can randomly start to use up to 80% of my disk. Yet I have no idea as to why. When I go into task manager, it only says that "system" is using so much disk, but I have like no idea what that means. It also only seem to happen when I am not actively using my computer, although that is not always the case. If i'm gaming, it works perfectly fine. When I am on a browser it also works perfectly fine where it may go up to like 5% at max.

I did do a virus scan a while ago though it didn't find anything. Might try it again just to be sure. Other than that, I seriously have no idea :/

There may be too many processes going on in the background. Do you have things like Edge browser installed? That could be a culprit. You can turn off many things like that via Settings app/Privacy/Background apps. There's a radio button that toggles to "off" for all apps (Edge does NOT have to run in the background) or you can choose.

How do you know the disk is running that highly? Do you open Task Manager? Next time maybe you can click somewhere inside the Disk space where the % is and it'll show you the main culprits. Edit: I see you did that already. I have had this before and I did a clean boot. It was some kind of subtle driver conflict.

use resource monitor to see what is using the disk

Guess it's worth a try. Cause it only happens when computer is inactive. As soon as I move the mouse, it goes down to 0. It actually seems to even reach 100% at times.

Yeah, that doesn't help. Still just says "system"

what files are being accessed?
location will help alot if its not just in windows directories

How do I see that? I have not really used resource monitor before so I apologize if i'm being annoying here.

on the disk section, it has files, expand that column to fit the entire file name

You can also try to boot into Safe Mode for a short while, then boot back into regular Windows. That may"unhook" whatever's going on. The effects if any may only be temporary though.

If not, as a last resort, you can repair-install Windows, keeping all apps and data. You download the ISO onto the desktop and run it as administrator rather than the USB method which wipes everything. You would then get a Windows.old which you can delete later if you wanted.

Inactive system w/ Win10/11 = Its most likely doing a disk defrag / disk optimize; or running AV scans with Defender. That's normal.

I turn all that junk off though on all my PCs.
