Repeated PAGE_FAULT_IN_NONPAGED_AREA (0x50) BSOD while playing PUBG – WinDbg shows execution of freed memory

Hello,

I’m trying to determine the cause of repeated BSODs while playing PUBG. The crashes are not always identical, but this dump shows PAGE_FAULT_IN_NONPAGED_AREA (0x50).

System specifications:

  • CPU: Intel Core i5-14600KF

GPU: NVIDIA GeForce RTX 5060 Ti Motherboard: ROG STRIX Z790-A GAMING WIFI S DDR5 BIOS: American Megatrends International, LLC. 2001 — 2025/04/25 OS: Windows 10 x64 Game: PUBG (TslGame.exe)

The BIOS has never been updated since the motherboard was purchased.

WinDbg analysis

!analyze -v reports:

PAGE_FAULT_IN_NONPAGED_AREA (50)

Arg1: fffff803b611ff14, memory referenced. Arg2: 0000000000000010 Arg3: fffff803b611ff14, If non-zero, the instruction address which referenced the bad memory Arg4: 0000000000000000

AV.PTE: Invalid AV.Type: Execute

PROCESS_NAME: TslGame.exe

FAILURE_BUCKET_ID: AV_nt!MiSystemFault

The trap frame shows:

rip=fffff803b611ff14

fffff803`b611ff14 ?? ???

I also checked the address with !pte:

0: kd> !pte fffff803b611ff14

pfn 38d0cc ---DA--KWEV not valid

Page has been freed

!pool could not find a valid pool allocation for this address either.

The faulting thread was attached to PUBG:

Attached Process: ... Image: TslGame.exe

and !thread reports:

Win32 Start Address BEDaisy

The loaded modules include:

BEDaisy.sys Wed Oct 9 11:15:06 2024

nvlddmkm.sys Tue Jan 20 16:11:41 2026

My questions

From these results, does this look more like:

A RAM / memory-controller stability issue? A driver corrupting memory or using a freed memory address? A possible BattlEye (BEDaisy.sys) issue? A BIOS / firmware compatibility issue? Something related to the NVIDIA driver?

Since the motherboard is still running BIOS 2001 from April 25, 2025, I am also considering updating the BIOS and testing again with BIOS defaults.

Unfortunately, this Q&A forum does not allow me to upload the original .dmp file, so I can only provide the relevant WinDbg output here.

If anyone can interpret these results or recommend additional WinDbg commands/tests, I would really appreciate it.

Thank you!

Hi, ForeverYoung Ad

The dump shows that Windows attempted to execute memory that had already been released, but it does not identify which component originally corrupted that memory. Since the thread starts in BEDaisy.sys, BattlEye is involved in the crash path, although it may be reacting to instability caused elsewhere.

Here are some suggestions you can try:

Disable XMP and any CPU/GPU undervolt or overclock, including settings applied through Armoury Crate, MSI Afterburner, or similar tools. Test PUBG with the memory running at its standard speed. If it still crashes, test with one RAM stick at a time.

Completely remove and reinstall BattlEye rather than only verifying PUBG. Run Uninstall_BattlEye.bat from the game’s BattlEye folder, restart Windows, then run Install_BattlEye.bat as administrator. BattlEye operates as a kernel-mode driver, so a damaged or incompatible installation can cause this type of crash.

Use DDU in Safe Mode to remove the NVIDIA package, then install a different stable Game Ready driver, preferably one version older rather than the same January 2026 build. DDU removes driver-store leftovers that a normal reinstall can retain.

If crashes continue with stock settings and different RAM sticks, the CPU or motherboard should be tested separately.

Thank you for your patience in reading, I hope this information has been helpful to you.
