Random window freezes (mouse works) caused by Samsung NVMe Controller driver v3.3

(Topic created: a week ago)


I have had random window freezes happen for a few months starting in September 2023 with Windows 10. I would use the computer as usual and then one window would freeze. The mouse would still move so I would click other windows and eventually those froze also and just the mouse moved. Sometimes the mouse would stop moving. Only way to fix any of this was to reboot but then sometimes the lock screen would freeze. On some occasions I would go into Task Manager and once in a while it would still work and refresh and I noticed the DISK was at 100% utilization but not program was reporting 100% usage. I thought it was some new Windows update causing havoc.

Eventually I did a lot of searching and stumbled along a few things to try and think about. I started thinking what I installed around September 2023 and remember that I updated the Samsung NVMe Controller driver from I believe 2.2 (95% sure) to 3.3. I did the things below and eventually determined the Samsung NVMe Controller driver v3.3.0.2003 was causing the problems but I have no clue why. I uninstalled it and am running the Microsoft controller without issues.

Can Samsung look into this and figure out why my PC went crazy with Samsung NVMe Controller driver v3.3.0.2003 and patch it with a new version?

Not sure if this helps but I remember reading on one page somewhere that the SSD sends something and Windoes freaks out so you need to go into Device Manager or regedit (don't remember which) to turn something off. I would guess this might be the issue; that the 3.3 driver added something causing the SSD to do something knew that Windows had no idea how to deal with.



Things I changed sometime In September 2023:
Changed NVM Driver to 3.3
Installed Samsung Magician 8.0
Removed BitDefender
New Windows Updates

Before starting software removals:
I ran the device in safemode and sure enough the same screen freeze but mouse moves issue would occur. At that point I knew the NVMe driver was likley 99.9% the problem.
MalwareBytes hardware acceleration was off before starting removals.

Log of Debug Actions:
9:29PM Removed Samsung Magician

1:00AM Deselected Malwarebytes Protection, quit, and allowed Windows Defender to run.

10:16PM Remove Samsung NVMe Controller driver v3.3.0.2003 1/21/2020 (Installed 9/16/2023 9:48:07PM)
Deleted SW and then PC wouldn't boot and attempted to fix itself in recovery mode but didn't help resolve issues.
Went into safemode and device booted fine using Standard NVM Express Controller.
Rebooted and everything was fine with Standard NVM Express Controller 10.0.19041.3636.

1:05AM No issues so far even with Malwarebytes using hardware acceleration and running intense anatomical renders.

Regarding my comment "I remember reading on one page somewhere that the SSD sends something and Windoes freaks out so you need to go into Device Manager or regedit (don't remember which) to turn something off."

I think I found the page: https://www.drivereasy.com/knowledge/100-disk-usage-windows-10-fixed/

Check Fix 7. Maybe this is the cause of my issues with Samsung NVMe Controller driver v3.3.

It talks about going into the ACHI driver details and setting MSISupported key to 0.
