Often crashes on my HP OMEN 15 laptop

[noonmoon]

I am super frustrated with constant crashes on my Windows 11 HP omen 15-en0xxx. some back ground, i updated to windows 11 without updating any drivers or bios. I was also experiencing issues with windows anti-virus messaging me about: vulnerableDriver:WinNT/winring0 in razer synapse service.sys. so I completely Uninstalled anything related to razer. Razer issue was also happening during previous window's version. The anti-virus stopped after removal of razer .sys files.

Recently the crashes have gotten very frequent. The messages upon crash are always from one of these:

Kmode_exception_not_handled, what failed: fltmgr.exe.

irql_not_less_or_equal, what failed: ntoskrnl.exe

Attempted_execute_of_noexecute_memory (0xfc)

What I've done so far: made sure every driver is updated. Checked bios is updated. Ran extensive system tests through BIOS. Also ran through HP hardware support app. No issues found at all. I've ran /sfc scannow. And no issues found either. I did do a reroll to a previous windows 11 version.

I dont know what to try next. 

Microsoft Windows 11 Home 10.0.26200 Build 26200.

HP OMEN Laptop 15-enOxx x64-based AMD Ryzen 7 4800H with Radeon Graphics, 2900 Mhz, 8 Core(s), 16 Logical.. Bios version: AMI F.25, 10/28/2024 Bios mode: uefi

Hi @noonmoon,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

I can feel how exhausting and frustrating this must be, especially when you’ve already done so much to troubleshoot. You’ve been incredibly thorough, and that tells me you’re serious about resolving this. Let’s take a deeper look together and find a path forward.

Next Steps to Try

1. Check for Memory Issues (RAM)

Even if BIOS tests passed, use Windows Memory Diagnostic:

• Press Windows + R, type mdsched.exe, and hit Enter.
• Choose Restart now and check for problems.
• Let it run and check the results in Event Viewer after reboot.

2. Run DISM to Repair Windows Image

Sometimes SFC isn’t enough. Try: DISM /Online /Cleanup-Image /RestoreHealth

Run this in Command Prompt (Admin). It can fix deeper system corruption.

3. Clean Boot to Rule Out Conflicts

This helps isolate third-party software issues:

• Press Windows + R, type msconfig.
• Go to the Services tab, check Hide all Microsoft services, then click Disable all.
• Go to Startup tab > Open Task Manager, disable all startup items.
• Restart and observe system stability.

4. Check for Minidump Files

These files contain crash details:

• Navigate to C:\Windows\Minidump.
• If files exist, I can help you analyze them to pinpoint the faulty driver or module.

5. Consider a Fresh Windows Install

If nothing else works, a clean install (not just a rollback) might be necessary. You can:

• Back up your data.
• Use the Windows 11 Media Creation Tool to create a bootable USB.
• Reinstall Windows from scratch.

I hope this helps.

Take care and have an amazing day!
