ACER PNH16-72 BSOD / throttling after fresh Win 11 install

I have the laptop since Feb 2025 and worked perfectly until Microsoft issued the Win 11 24H2 version and everything started to go wrong. Apps that worked fine before started to freeze or shut down and BSODs started.  

I installed Win11 24H2 from MS website, but the issues continued.  

I managed to create a bootable USB with Win 11 23H2 (from UUPDump.net) but it only got

marginally better, not like it was in the beginning. 

On Friday 13June2025 I noticed the PredatorSense app (it was the latest version from Acer support website) seemed to not work right, as it was clocking the CPU to about 5000MHz even on balanced or quiet mode.  

Yesterday (14June2025) I have again reinstalled the Win 11 23H2, did all the updates and everything looked good, only to have today two BSODs within a couple of hours, without running anything other than a few Chrome pages.  

In the meantime, I have also installed the HWiNFO app and immediately after boot-up it shows Core Thermal Throttling on multiple cores without running any software at all. It usually starts throttling on P-core 4 and P-core 5 on idle, expanding to all P-core 0 to P-core 7 and a few E-cores as well when I download or install a new software.  

I always use the laptop on a desk, with normal ventilation. 

I didn't load any drivers from ACER website, only what Windows update found.  

I've seen some advice here for a similar laptop with a different issue that included booting in Safe Mode, but I don't have that option in BIOS. 

Cmd Sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth found no issues 

Any help would be appreciated.

    A fresh installation of Windows 11 on an Acer Predator Helios Neo 16 (PHN16-72) can sometimes lead to the CPU drawing excessive power and experiencing thermal throttling, even in non-CPU intensive tasks. This issue was not present with the factory-installed Windows 11 or when upgrading from Windows 10.
    Here's a breakdown of the problem and potential solutions:-

    The Problem: Abnormal CPU Power Draw:-
    The CPU, specifically the Intel Core i7-13700HX, may draw significantly more power than it should (e.g., 100W).
    Overheating:
    This excessive power draw leads to high temperatures, potentially reaching 100°C.
    Thermal Throttling:
    The system may throttle the CPU to prevent further overheating, resulting in performance issues.
    Clean Install Issue:
    The problem is specific to clean installations of Windows 11, not upgrades or the original factory image.
    Possible Causes:
    Driver Issues:
    Missing or outdated drivers, particularly for the chipset, graphics card, and other components, can cause unexpected behavior.

    BIOS Settings:
    Certain BIOS settings, like Virtualization-Based Security (VBS), might not be properly configured after a clean install.
    Software Conflicts:
    Some third-party software or background processes could be interfering with the system's power management.
    Hardware Issues:
    While less likely, hardware problems like overheating or disk errors could also contribute.

    Troubleshooting Steps:-
    1. Install/Update Drivers:
    Download and install the latest drivers for your Acer Predator Helios Neo 16 from the official Acer support website.
    Pay close attention to chipset, graphics card, and any other relevant drivers.
    2. Check BIOS Settings:
    Access the BIOS settings (usually by pressing F2 or Delete during startup).
    Ensure VBS and other virtualization features are properly configured, potentially disabling them if they are causing issues.
    Check for any BIOS updates and install them if available.
    3. Review Power Options:
    Go to Windows settings, then System > Power & battery, and select the Balanced power plan.
    You can further customize power settings within the Control Panel under Power Options.
    4. Check for Resource-Heavy Software:
    Use Task Manager to identify any programs or processes that are consuming excessive CPU resources.
    Close or uninstall any unnecessary software.
    5. Consider a System Restore or Reset:
    If the problem persists, try restoring your system to a previous working state using System Restore.
    If that doesn't work, consider resetting Windows 11, which will reinstall the operating system while keeping your files.
