Acer Nitro V15 (ANV15-51, RTX 4050) – DPC_WATCHDOG_VIOLATION (0x133) while gaming, V2 log attached

frostXD · May 27, 2026

Problem summary:
The laptop crashes with DPC_WATCHDOG_VIOLATION (0x133) during gaming. The crash happens within 5–30 minutes of gameplay. Game stopped working and laptop laggs for a while before crashing.
What I have already tried (no success):

Clean reinstall of Windows 11 from Microsoft Cloud.
DDU in Safe Mode → clean installation of NVIDIA drivers:
Disabled Fast Startup and PCIe Link State Power Management.
Ran Windows Memory Diagnostic – no errors.

V2 Log Collector output:
Link: V2 Log collector

Does anyone know how to fix this?
Thank you in advance for any guidance.

The DPC Watchdog Violation (Stop Code 0x133) means a system process or hardware driver took too long to complete a task, forcing Windows to crash to prevent data corruption. This is most frequently caused by outdated SSD/hard drive drivers, corrupted system files, or conflicting third-party software. [1, 2, 3]
Apply the following targeted fixes, starting with the most common culprits:

1. Update SSD and Hard Drive Drivers
Solid State Drives (SSDs) are the most common cause of this error. [1, 2]

Right-click the Start button and select Device Manager.
Expand the Disk drives section.
Right-click your drive and choose Update driver.
- Click Search automatically for drivers.
- Note: If you use a Samsung or Western Digital drive, it is highly recommended to download the dedicated manufacturer software (e.g., Samsung Magician) to update the drive's firmware directly. [1, 2, 3]

On a side note... CPU-Z will tell you what RAM you have, and Crystal Disk Info will tell you what drives you have.

Use CPU-Z to get your System Specs...

CPU-Z (free), will show you make/model for everything except: drives, case and power supply. You'll need to add make/model for monitor, keyboard and mouse as well. That info should be easy to find. Portable version: https://download.cpuid.com/cpu-z/cpu-z_2.17-en.zip

Are there any newer stable NVIDIA drivers for Acer Nitro V15 (ANV15-51, RTX 4050)?

Acer provides this driver:
VGA Driver (RTX 4050) — NVIDIA
Release Date: 2024/01/12
Version: 31.0.15.4618

This driver seems quite old for newer games, so I'm wondering if there are newer stable alternatives.

zbook · May 29, 2026

That is the best tested driver.

Newer does not equal better.

The best driver is the driver that has the most stability and least instability.

Acer has chosen this specific driver (2026/01/30).

frostXD · May 29, 2026

I have completed all the steps you provided:

WMIC – confirmed installed
Tuneup_plus_log.bat – ran successfully
Regback – enabled automatic registry backup
DDU + Acer OEM driver – clean uninstall of NVIDIA driver in Safe Mode, then installed Acer driver 31.0.15.4618 from the Acer website
Windows Update driver blocking – configured to prevent automatic driver updates

I launched Forza Horizon 6 to test stability, and the game itself is now asking me to install a newer NVIDIA driver. It refuses to run or warns that performance may be degraded.

Rehook the internet.

zbook · May 29, 2026

Please test the Acer driver for one week.

If stable then there is highly unlikely a hardware problem.

Then try any driver forza likes for comparison.
