When Gaming, Monitors goes Black screen and GPU Fans goes to 100%

Troubleshooting Gaming Black Screen and GPU Fan Overload: A Comprehensive Guide

Experiencing abrupt black screens during gaming sessions combined with GPU fans running at maximum speed can be a frustrating issue for PC enthusiasts. If you’ve encountered similar problems, you’re not alone. This article aims to explore potential causes, effective troubleshooting steps, and best practices to resolve such issues, based on real-world experiences and established technical guidance.

Understanding the Issue

Many gamers and PC builders have reported experiencing black screens during gaming, often accompanied by GPU fans spinning at full speed. These symptoms may indicate underlying hardware or software problems, including power supply issues, driver conflicts, overheating, or hardware faults.

Common Symptoms:

Sudden black screen during gameplay
GPU fans operating at 100% RPM
Temporary resolution after reconnecting the GPU power cable
Stable performance in desktop mode and non-gaming tasks

Case Study: A Typical Gaming Rig

Here’s an example configuration where such issues have been observed:

Power Supply: Pure Power 1000W 80+ Gold
Motherboard: Gigabyte B660 Gaming X DDR4
Processor: Intel i5-12600KF
Graphics Card: Gigabyte RTX 4070 Ti Gaming OC
Storage: Samsung 990 Pro 2TB M.2 SSD
Memory: G.Skill RipJaws 32GB DDR4, XMP 3600MT/s
Operating System: Windows 11 Pro 24H2
Monitors: Ultrawide 3440×1440 @165Hz, standard 1920×1080 @120Hz

This setup maintains good temperatures, stable performance, and smooth gameplay; yet, intermittent display blackouts and GPU fan issues can still occur.

Troubleshooting Steps

Hardware Verification
Ensure all power connections to the GPU are secure.
Test the GPU in another PCIe slot or system if possible.
Check the power supply’s capacity and stability—your 1000W PSU is generally sufficient but verify no faults exist.
Driver and Software Maintenance
Use Display Driver Uninstaller (DDU) to completely remove existing GPU drivers.
Reinstall the latest GPU drivers directly from the manufacturer’s website.
Keep your Windows OS and BIOS updated to minimize compatibility issues.
Thermal and Overclocking Checks
