Frequent DPC_WATCHDOG_VIOLATION when trying to load webpages and/or videos; How do I fix this?

Question

Computer Info: Alienware M17x R3 running Windows 10 Pro 64bit, NVIDIA Geforce Gtx 460m gpu, Intel(R) Core(TM) i7-2820QM CPU @ 2.30GHz 2.30 GHz, 16gb DDR3 ram. Recently Formatted both new Samsung 870 EVO SSDs (500gb each) with a new Windows 10 installation; they are in a Raid 0 array. Using Bitdefender total security/vpn

Was previously getting the following in dump file crashes:

SYMBOL_NAME:  nvlddmkm+555496

MODULE_NAME: nvlddmkm

IMAGE_NAME:  nvlddmkm.sys

STACK_COMMAND:  .cxr; .ecxr ; kb

BUCKET_ID_FUNC_OFFSET:  555496

FAILURE_BUCKET_ID:  0x133_ISR_nvlddmkm!unknown_function

OS_VERSION:  10.0.19041.1

BUILDLAB_STR:  vb_release

OSPLATFORM_TYPE:  x64

OSNAME:  Windows 10

FAILURE_ID_HASH:  {f97493a5-ea2b-23ca-a808-8602773c2a86}

Followup:     MachineOwner

So I downloaded the oldest available NVIDIA driver for the GPU and am now getting the following in the dump file:

DPC_WATCHDOG_VIOLATION (133)
The DPC watchdog detected a prolonged run time at an IRQL of DISPATCH_LEVEL
or above.
Arguments:
Arg1: 0000000000000000, A single DPC or ISR exceeded its time allotment. The offending
	component can usually be identified with a stack trace.
Arg2: 0000000000000501, The DPC time count (in ticks).
Arg3: 0000000000000500, The DPC time allotment (in ticks).
Arg4: fffff803816fb320, cast to nt!DPC_WATCHDOG_GLOBAL_TRIAGE_BLOCK, which contains
	additional information regarding this single DPC timeout

Hello

The DPC_WATCHDOG_VIOLATION (133) error is usually related to a device driver issue and appears on a Blue Screen of Death (BSOD). The error message is triggered by the DPC Watchdog Timer when it detects a DPC (Deferred Procedure Call) is running past its predetermined runtime.

In your case, it seems like the cng.sys file might be causing the issue. This file is a system file that is associated with the Cryptography Next Generation (CNG) feature of Windows. It’s used for software-based encryption and decryption.

Here are some steps you can take to resolve this issue:

Update Your Drivers: The DPC Watchdog Violation error can be caused by outdated or incorrectly installed drivers. You should check if there are any updates available for your drivers, especially those related to the cng.sys file.

Check for System File Corruption: Use the System File Checker tool to repair missing or corrupted system files. To do this, open Command Prompt as an administrator and type sfc /scannow.

Check for Malware: Run a full system scan with your antivirus software to check for any malware that might be causing the issue.

Perform a System Restore: If none of the above solutions work, you might want to consider performing a system restore to revert your system back to a state before the issue started occurring.

Remember to always back up your data before making any major changes to your system.
