Help, PC Blackscreening on Idle with 5080 fans going at 100% 10-20 minutes after playing Space Marine 2 [5800x3d + 5080]

Understanding and Addressing GPU Black Screen Issues with High Fan Activity: A Case Study

Introduction

Growing concerns over graphics card stability can be perplexing, especially when symptoms such as sudden black screens and fan anomalies occur intermittently. Recent reports from gamers utilizing high-performance GPUs like the NVIDIA GeForce RTX 5080 highlight such challenges. This article aims to explore these issues comprehensively, examining possible causes and suggesting troubleshooting strategies.

Background

Users with robust gaming setups often report sporadic black screens accompanied by GPU fan surges, typically happening during system idle or after specific gaming sessions. For instance, a user with a high-end PC configuration experienced black screens and the GPU fans ramping up to maximum speeds approximately 10-20 minutes after playing titles like Space Marine II, with no issues during active gameplay.

System Specifications

• Processor: AMD Ryzen 7 5800X3D
• Graphics Card: NVIDIA GeForce RTX 5080
• Motherboard: ROG Strix 450F
• RAM: 32GB Corsair Vengeance (operating at 2400MHz without XMP)
• Power Supply: 850W 80 Plus Gold (PowerColor)
• Operating Environment: 4K gaming with DLSS and MFG enabled

Initial Troubleshooting Attempts

Standard procedures, such as utilizing Display Driver Uninstaller (DDU) to remove and reinstall GPU drivers, were employed. Unplugging and reseating power connectors, notably the 12-pin adapter, and disabling overclocking settings provided some relief but did not fully resolve the recurrent black screens.

Observations and Patterns

• Occurrence is infrequent, roughly twice a week.
• Often follows a gaming session, particularly after exiting certain titles.
• Happens predominantly during system idle or non-intensive tasks, such as browsing via Discord.
• Not reproducible reliably, complicating diagnosis.
• Previous GPU models (e.g., AMD Radeon 5700XT, 6900XT, 7900XTX) exhibited glitches but not with identical symptoms, especially concerning fan behavior.

Potential Factors

1. Hardware Compatibility and Fit

2. The RTX 5080, due to its size, may experience seating issues within the case, potentially affecting connections and signal stability.

3. Driver and Firmware Stability

4. Although driver reinstallation was attempted, ongoing driver bugs or compatibility issues could cause system hangs or GPU hangs, leading to black screens.

5. Power Delivery

6. Insufficient or unstable power
