Problem
I am experiencing recurring CRITICAL_PROCESS_DIED (Bug Check 0xEF / 239) BSODs. The crashes occur most frequently during heavy GPU and/or VRAM utilization, particularly when VRAM usage exceeds physical memory and begins utilizing shared system memory.

Environment & History
* System Age: Approximately 4 years old.
* Issue Duration: Approximately 18 months.
* System profile is completed with as much detail as possible.

What I tried
* Storage Testing:
* Temporarily replaced my primary Sabrent SSD with a borrowed 1TB SSD. The BSODs completely disappeared under the exact same workloads.
* Returned the borrowed drive, installed a spare 512GB SSD, and performed a clean Windows installation. The crashes returned.
* Reinstalled the original Sabrent SSD, performed another clean Windows installation, and added a new heatsink to improve SSD cooling. The issue persists.
* Memory Testing:
* Ran MemTest86 (multiple full passes completed approximately 6 months ago). No errors were detected.
* VRAM Testing:
* Ran FurMark's VRAM test with 16GB or 20GB memory allocation. This consistently triggers a crash after several minutes.
* Driver Testing:
* Tested both the latest NVIDIA drivers and an older release from mid-2024. The issue occurs regardless of the driver version.

Reproduction Steps
The most reliable way to trigger the crash is initiating a secondary GPU-related task while the GPU is already under heavy load:
1. Running a FurMark VRAM test at maximum VRAM utilization, then pressing the Windows key to open the Start menu or Search.
2. Opening and using applications like Discord or Task Manager during a FurMark VRAM test.
3. Opening browser tabs while gaming when VRAM usage is already high.

Actual Behavior
In some instances, applications like Discord (or other open windows) briefly become unresponsive while the rest of the system continues functioning normally. Shortly afterward, the system crashes with a CRITICAL_PROCESS_DIED BSOD.

Extra details
Given that the issue completely disappeared when using my brother's 1TB SSD but returned on both my original Sabrent SSD and the spare 512GB SSD (even after clean Windows installations), I am unsure if this points to a configuration/driver issue or something else entirely.

I can provide additional hardware details or logs as needed. Thank you for your time and assistance!
