Hello Pin Stops working, followed by Memory Integrity gets turned off

Hi. Can you help me?

I keep resetting my Laptop [ROG Zephyrus G14 (2025)] after these problems and they keep coming back after about 4 days.

I stopped downloading two games I thought may be causing the issues and still have the same problem.

First problem:

"Something happened and your PIN isn't available."

- I keep having to set a new pin or switch to password. Ideally I'd switch to nothing at all but it isn't an option on Windows 11?

Second Problem:

"Memory integrity is off"

- I get this warning when I randomly turn on my PC, typically not long after the first problem (possibly 1-3 restarts after).

Again, I can keep restoring or resetting my PC but it keeps coming back again, typically not long after 4 days.

Fix the Corrupted PIN Folder (NGC Error)

If Windows still bugs you or fails to let you remove it cleanly, clear the corrupted credential folder causing the "Something happened" loop:

• Log in using your password.
• Press the Windows Key + R, type C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft and press Enter.
• Locate the folder named Ngc.
• Right-click the Ngc folder, select Rename, and change the name to Ngc.old (you may need administrator permission).
• Restart your PC and set a fresh PIN or leave it disabled. You can follow official guides on the Microsoft Support portal if account syncing causes further trouble.

For the Memory Integrity issue, there may be some corruption that is causing Windows to turn it off.

Simple first step is to open an elevated (Run as Administrator) Command prompt, and run sfc /SCANNOW

Run sfc until it returns no errors.

Then, turn Memory Integrity on.

The windows Hello problem may be related to the memory integrity error fix that first.

Memory Integrity (part of Windows Core Isolation) is usually turned off on ASUS ROG laptops due to incompatible third-party drivers (such as older ASUS software components, RGB controllers, or anti-cheat drivers) or because CPU virtualization is disabled in the BIOSMemory integrity (part of Windows Core Isolation) is typically disabled or prevented from turning on due to incompatible third-party drivers or CPU virtualization being turned off in the BIOS.

Step 1: Identify Incompatible Drivers​

1. Open the Start menu, search for Core isolation, and open it.
2. Toggle Memory integrity to On.
3. If Windows blocks it, click Review incompatible drivers.
4. Note down the Published name (e.g., oemXX.inf) and Original name of any listed drivers. Common culprits on ASUS laptops include legacy lighting drivers (Aura), older Armoury Crate components, or legacy anti-cheat software.

Step 2: Remove Conflicting Drivers​

Choose one of the methods below to remove the blocking driver files:

• Method A: Via Command Prompt (Fastest)
  1. Open the Start menu, search for cmd, right-click Command Prompt, and select Run as administrator.
  2. Run the following command (replace oemXX.inf with the specific file name identified earlier):
     DOS
     
     pnputil /delete-driver oemXX.inf /uninstall /force
     
     
  3. Repeat for any other incompatible .inf files listed.
• Method B: Via Device Manager
  1. Right-click the Start button and select Device Manager.
  2. Click View in the top menu and choose Devices by driver.
  3. Find the matching oemXX.inf driver name, right-click it, and select Remove driver (ensure "Delete the driver software for this device" is checked).

Step 3: Check BIOS Virtualization Settings​

If no driver conflicts are reported but the option is grayed out:

1. Restart your laptop and press F2 repeatedly to enter the BIOS utility.
2. Press F7 to switch to Advanced Mode.
3. Navigate to the Advanced tab and ensure SVM Mode (AMD Virtualization) or Intel Virtualization Technology is set to Enabled.
4. Press F10 to save changes and exit.

Step 4: Re-enable Memory Integrity​

1. After rebooting into Windows, open Core isolation again.
2. Toggle Memory integrity to On.
3. Restart your laptop when prompted to complete the setup.

Per co-pilot
The two issues you’re seeing — the Hello PIN breaking and Memory Integrity turning off — usually point to the same root cause: a driver or security component keeps reinstalling and corrupting Windows’ secure storage. That’s why the problems return every ~4 days even after a reset .

Here’s the fastest way to narrow it down:

• Check the Memory Integrity incompatible drivers list Windows Security → Device Security → Core Isolation → Memory Integrity.Windows will name the driver that’s forcing it off .
• Check Windows Update → Driver Updates See if the same driver keeps reinstalling around the time the PIN breaks.
• Check ASUS updates (Armoury Crate) ACPI, System Control Interface, Precision Touchpad, AMD PSP/chipset drivers can all cause this if a bad version is pushed.
• Look for leftover anti‑cheat services Even if you stopped downloading the games you suspected, anti‑cheat components may still be present and updating themselves .
• TPM reset (after backing up BitLocker keys) This often fixes repeated Hello PIN corruption.

And yes — Windows 11 requires at least one sign‑in method, so “nothing at all” isn’t an option
