How to fix DPC Watchdog Violation Error

Question

My laptop- Acer aspire lite AL15G-52 had been working without any errors for around 6 months, when first, my headphone jack stopped working then my speakers, so i had to use an adapter for my headphones to work.

The adapter was a bit loose, and would disconnect when disturbed, until I push it around till it reconnected.

This happened till a few months ago where the adapter upon disconnecting, a bsod happened. The disconnection would happen more frequently when the laptop was being placed under high loads.

It had been tolerable as i would just restart my computer, but now it would start blue screening every 30 mins or so with one of the following

DPC Watchdog Violation Error -
cumulative update install error 0x800f0983
WHEA_UNCORRECTABLE_ERROR
driver power state failure
kernel level security check failure

driver irql not less or equal

All of these when checked online indicate a driver issue. At first I tried to do some digging, and thought of the intel smart sound drivers and other sound related drivers. I uninstalled the drivers, removed it from the computer, restarted and the bsods still occur, even when i have not connected my adapter and it has not even booted.

I also have tried the verifier command, but it did not crash. Also tried was the memory scanner and the one that checks integrity of system files.

I reset my computer which fixed my speakers, and my headphone jack powered one half of my headphone, but that was it and the bsods kept coming. Another issue is that the acer issued (i think) software-Fn hotkeys and osd-Control center for controlling fan rpm often gets stuck at around 2k rpm and starts thermal throttling - 90 degrees at idle, so i have to often set it at max rpm-7k for around 60 degrees. This is combined with me using Throttle stop, witg turbo boost disabled, at balanced modeI am very sorry for the length, but i wanted to include every detail i could.

Hello,

 

Based on the blue screen logs and device issues you described, your Acer Aspire Lite AL15G-52 is experiencing two main interconnected issues:

1.Frequent blue screens caused by driver anomalies: Logs clearly point to errors in drivers such as IntcUSB.sys, HKMouFltr.sys, HKKbdFltr.sys, RNDISMP.sys, and combined with rt640x64.sys (mentioned in Event Viewer), driver corruption, incompatibility, or conflicts are the core causes.

2.Overheating exacerbating hardware instability: The fan control software (Acer Control Center) frequently gets stuck, leading to CPU overheating (90°C at idle). Overheating further destabilizes hardware operation and worsens driver errors.

 

What are these drives:

1.IntcUSB.sys (Intel USB Driver): The first blue screen log indicates a tag mismatch error when handling device removal locks, a typical driver logic anomaly. This may result from driver corruption or incompatibility, often triggered by frequent USB device disconnections. 2.HKMouFltr.sys and  HKKbdFltr.sys(These 2 drivers are provided by Acer, and seem to be related to the Acer Control Center, possibly a hotkey driver, or a touchpad/mouse driver, so it is recommended to check with Acer.): The DRIVER_IRQL_NOT_LESS_OR_EQUAL error in three  dumps shows these driverr accessed invalid memory at a high-priority interrupt level, likely due to corrupted driver files or conflicts with other input device drivers. 3.RNDISMP.sys (Network-related Driver) and rt640x64.sys (Realtek Network Adapter Driver): The third log’s kernel list corruption is linked to abnormal timer handling in network drivers. rt640x64.sys (Realtek network driver) and RNDISMP.sys may suffer from instability due to outdated versions or conflicts.

 

 

So, for BSOD issues, visit Acer's official website, search for your model "AL15G-52":

Update Intel USB and Chipset Drivers

Uninstall Acer Control Center, hotkey driver. Reinstall Acer Touchpad/Mouse Drivers.

Update Network-related Drivers

 

For overheating issue:

1.Disassemble the laptop (or consult a professional) to clean dust from the fan and heatsink. Replace the CPU thermal paste (dried paste drastically reduces cooling efficiency) to ensure unobstructed airflow.

2.Uninstall Acer Control Center and related thermal management software, then download and install the latest version from the official website (older versions may have compatibility bugs). If the software still malfunctions, try alternative tools to manually control the fan, preventing the CPU from staying above 90°C.

 

 

After completing the steps above, monitor if blue screens persist. If they stop, the driver and overheating issues are resolved. If blue screens continue, hardware faults (e.g., physical damage to USB ports, motherboard power anomalies) may be the cause. Contact Acer support for professional hardware diagnostics (frequent adapter disconnections could lead to loose port soldering).
