HP OMEN (AMD) – Crashes and BSODs return after reboot, but system is 100% stable right after BIOS.

[agathaxat]

Hey everyone,

I'm dealing with a very strange and frustrating issue on my HP OMEN 15 en0xxx laptop with an AMD processor.

The laptop is equipped with solid hardware, but I’m experiencing frequent BSODs, sudden reboots, and freezes – even while doing simple tasks like browsing or watching YouTube.

---

What I've tried so far:

• Installed the latest drivers from AMD, NVIDIA, and Windows Update – the issue got worse, crashes became more frequent.

• Switched to the recommended drivers from HP – slightly better, but the BSODs still occur.

• Ran MemTest86 for several hours, SSD and CPU/GPU stress tests, HP’s own diagnostics – no hardware issues found.

• Did clean Windows installs multiple times (disabled Fast Startup, disabled auto driver installs).

• Flashed both the latest BIOS version and older versions – but nothing changed permanently.

---

Here’s the weird part:

When I reset or re-flash the BIOS (even to the same version), the system becomes completely stable. I can game, work, stream – no crashes at all.

But once I restart or shut down and power on again, the crashes come back.

It feels like Windows or a driver is enabling something in the background – maybe related to ACPI, SMU, PSP, ASPM or microcode, and it causes the system to become unstable.

The BIOS on this OMEN device is very locked-down – there are no power or CPU settings, so I can’t disable anything manually.

---

Additional steps I’ve taken:

• Disabled Fast Startup via powercfg /hibernate off

• Removed ACPI/PSP-related devices in Device Manager

• Blocked Windows Updates and automatic driver installs

---

My questions:

1. Can Windows or AMD drivers modify BIOS behavior (e.g., enable power-saving functions or microcode changes)?

2. Has anyone had similar issues with AMD-based HP OMEN laptops?

3. Is there a way to block background firmware/microcode tweaks?

4. Are SMU/PSP/ACPI/ASPM issues known to cause instability like this?

5. Is there any way to get advanced BIOS options or a debug/testing version from HP?

---

I'd truly appreciate any help or insight – I've spent dozens of hours troubleshooting and I’m running out of ideas.

Again, the system works perfectly right after a BIOS reset, but that only lasts until the next reboot.

Thanks in advance!

@agathaxat, Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding HP OMEN 15 Crashes and BSOD Issues!

We're thrilled to have the opportunity to assist you and provide a solution. 

Experiencing Blue Screen of Death (BSOD) and system instability on your HP OMEN 15 with AMD processor can indeed be frustrating. Here are some steps you can try to troubleshoot and resolve these issues:

BIOS Update: Ensure that your BIOS is up-to-date. Outdated BIOS versions can lead to hardware compatibility issues. You can update it by visiting the HP Support page for drivers and downloading the latest BIOS version specifically for your laptop model.

Driver Verification: Although you mentioned that you have updated the drivers, ensure that you have downloaded the appropriate versions directly from the official sources:

• AMD for the chipset and GPU drivers.
• HP official website for any OEM-specific drivers, especially for AMD and BIOS.

System Diagnostics: Run HP's built-in hardware diagnostic tools to check if there is a hardware issue. You can access it by restarting the laptop and pressing Esc followed by F2 as soon as the computer boots.

Hyper-V and Virtualization: Sometimes, having Hyper-V or similar virtualization technologies enabled can cause instability with certain AMD hardware. Try disabling these from the BIOS (UEFI Firmware Settings).

Check for Conflicting Software: Software conflicts can also lead to BSODs. Ensure that there's no third-party antivirus or unnecessary applications running in the background that might be conflicting with the Windows system files.

Memory Check: Run a memory test to check for faulty RAM. Use the Windows Memory Diagnostic tool by typing "Windows Memory Diagnostic" in the Windows search bar and following the tool's instructions.

Reinstall Windows: As a last resort, consider performing a clean installation of Windows. Sometimes corrupted system files can lead to persistent issues after updates or driver changes. 

Hope this helps!

Take care, and have an amazing day!

Dear [Support Team / zoey7886],

Thank you for your response and the detailed troubleshooting steps.

I’d like to clarify what I’ve already tried:

• I ran a full hardware diagnostic (including extended tests) using HP's diagnostic tools. The scan took around 4 hours, and no issues were found.

• Additionally, I ran MemTest to check the RAM — the test completed successfully with no errors.

• I have already performed a clean installation of Windows 10, but the system continued to crash shortly after.

• I’ve also installed the latest available BIOS from the HP website. However, not only did this not solve the issue, but I found that many users reported that crashes started occurring after the BIOS update, which aligns with my experience.

• All drivers were installed from official sources — AMD for the chipset/GPU and HP’s website for OEM-specific drivers.

At this point, it seems like the issue may be rooted deeper, possibly at the firmware level, especially considering the number of users facing similar problems after the BIOS update.

I would greatly appreciate any further guidance or potential fixes you could suggest.

Best regards,
agathaxat

@agathaxat, Thanks so much for the detailed follow-up — it really helps us understand what you’ve tried so far (and it’s clear you’ve done a lot).

The fact that your system is completely stable right after a BIOS reset, but becomes unstable after reboot, strongly suggests a firmware-level or power management setting being re-enabled by Windows or a driver. This could indeed involve ACPI, SMU, or PSP interactions — and unfortunately, with locked-down BIOS on consumer OMEN models, manual control over these is limited.

To address your key concerns:

Yes, Windows and AMD drivers can trigger firmware features (like ASPM or CPU power states) after reboot, even if they aren’t exposed in the BIOS UI.

We’ve seen similar instability reported post-BIOS updates, especially on some AMD-based models.

There’s currently no official way to access advanced or debug BIOS settings on OMEN devices.

What we recommend next:

Try disabling device installation via Group Policy (if you haven’t already):
Go to gpedit.msc > Administrative Templates > System > Device Installation > Device Installation Restrictions and enable “Prevent installation of devices that match any of these device IDs.”
You can use this to block specific ACPI or PSP-related device IDs you’ve noted.

Consider trying Linux live boot (just for testing). If the system is stable in Linux after reboot, it may confirm it’s a Windows-specific power or driver conflict.
