Hello, The Salmon
Welcome to the Microsoft community.
Thank you for your feedback. I understand that you are experiencing a black screen and full fan speed issue, the event ID Kernel-Power 41 (63) indicates an unexpected system shutdown, which in combination with the Kernel-Processor-Power 55 (47) and Hyper-V-Hypervisor logs may be related to hardware power instability, CPU/GPU overheating, or driver/virtualization conflicts. conflicts. Below are some troubleshooting options:
- Power Supply Load Test
Even if you have replaced the power supply, you still need to verify that the power is matched:
Calculate the overall power consumption (including peak GPU power) using the OuterVision PSU Calculator.
Ensure that the new power supply's rated power ≥ the entire machine's peak power consumption × 1.5 (reserve a margin).
Temporary test:
Unplug the discrete graphics card and run games/high-load tasks using the core graphics to see if the problem recurs.
Hardware contact check
Disconnect all external devices (keep only the keyboard, mouse and monitor).
Re-plug the following components:
Graphics card (wipe gold fingers, replace PCIe slots).
Memory Stick (single rotate test).
CPU power supply cable (all 8+4pin interfaces need to be plugged firmly).

- Driver and System Configuration Fixes
Completely reinstall the GPU driver
Download the WHQL certified version (not the latest version) from the official website, such as NVIDIA 522.25 or AMD 22.11.2.
Turn off overclocking and virtualization
Enter BIOS:
Disable XMP/DOCP (memory overclocking).
Disable Intel VT-d/AMD-V (virtualization technology).
System Settings:
Search for “Windows Features” → Uncheck Hyper-V and Virtual Machine Platform.
Adjust the power plan
Press Win + R and type powercfg.cpl → select “High Performance”.
Click “Change Program Settings” → “Change Advanced Power Settings” → Modify:
PCI Express → Link State Power Management → “Off”
Processor Power Management → Maximum Processor Status → **99%** (Disable RWD)
- Monitor real-time temperature and voltage
Use HWiNFO to record sensor data (focus on GPU/CPU temperature, 12V voltage fluctuations).
When a crash is triggered, check for the following:
CPU/GPU temperature > 95°C
12V voltage < 11.4V or fluctuation > ±0.5V
IV. Fault Injection Test
Stress Test Tools
CPU: Run Prime95 (select Small FFTs).
GPU: Use FurMark (check “Burn-in”).
Power: Run Prime95 and FurMark at the same time for 15 minutes to see if the crash is triggered.
- Hardware Replacement Verification
Cross Test Components
Install the graphics card to another motherboard for testing.
Replace the power cables (especially the GPU's 8pin power cable).
Use a multimeter to measure the output voltage of each terminal of the power supply (12V needs to be stabilized within ±5%).
If none of the above steps work and the device is under warranty:
Contact the manufacturer to request a replacement motherboard or graphics card (provide memory dumps and HWiNFO logs as evidence).
Prioritize possible causes based on logs and symptoms:
Power supply instability (especially uneven distribution of multiple 12V).
GPU memory/core failure (runaway fan after black screen is common for graphics card hardware issues).
Motherboard VRM module overheating (check if the motherboard MOS heatsink is loose).
I look forward to your feedback.
