How to Troubleshoot and Solve PC Display and Fan Problems


What could cause my PC to lose display and ramp up the fans after running for a while?

I have a high-end PC with the following specifications:

  • Motherboard: ASUS ROG Strix B660-F Gaming WIFI
  • GPU: MSI GeForce RTX 4080 16GB GAMING X TRIO
  • SSD: Samsung 970 EVO Plus 500GB + another M.2 SSD from my old PC
  • CPU: Intel Core i7 13700K 3.4 GHz 54MB
  • PSU: Corsair RM1000e 1000W
  • CPU Cooler: NZXT Kraken Z73 360mm
  • RAM: Kingston Fury Beast RGB 32GB (2x16GB)
  • Fans: 6 Arctic P12 PWM + fanhub
  • The

problem occurs randomly, regardless of the load or temperature of the system. It can happen when I am gaming or just watching YouTube. The screen goes black and the fans go to full speed. I cannot find any error messages in the event viewer. I have tried reinstalling Windows 10, but the problem persists. How can I diagnose and fix this issue?


There are several possible causes for this problem, ranging from hardware issues to software glitches. Here are some of the most common ones and how to troubleshoot them:

  • Faulty or incompatible GPU driver: Sometimes, the graphics card driver can become corrupted or outdated, causing the display to crash and the fans to spin up. To fix this, you can try updating the driver from the manufacturer’s website, or uninstalling and reinstalling it from the Device Manager. You can also try using a different driver version, such as the latest stable or beta release.
  • Overheating or insufficient cooling: Even though you said the temperatures are fine, it is possible that some components are overheating or not getting enough airflow, especially if you have a high-end PC with powerful hardware. To check this, you can use a monitoring software like HWiNFO or MSI Afterburner to see the temperature and fan speed of each component. You can also open the case and inspect the fans, heatsinks, and dust filters for any blockage or damage. You may need to clean them, replace them, or add more fans to improve the cooling performance.
  • Insufficient or unstable power supply: Another possible cause is that your power supply unit (PSU) is not providing enough or consistent power to your PC, causing it to shut down or restart. This can happen if your PSU is faulty, old, or not powerful enough for your PC’s specifications. To test this, you can use a multimeter or a PSU tester to measure the voltage and current output of your PSU. You can also try using a different power outlet, power cord, or surge protector. You may need to replace your PSU with a higher wattage or quality one.
  • Faulty or incompatible hardware: Sometimes, the problem can be caused by a defective or incompatible hardware component, such as the motherboard, CPU, RAM, SSD, or GPU. This can happen due to manufacturing defects, physical damage, or improper installation. To diagnose this, you can try removing or swapping each component one by one and see if the problem persists. You can also use a diagnostic software like MemTest86 or Prime95 to test the RAM and CPU for errors. You may need to repair or replace the faulty component.
  • Software conflict or malware infection: Finally, the problem can be caused by a software conflict or a malware infection, such as a virus, worm, or ransomware. This can happen due to corrupted files, incompatible programs, or malicious attacks. To fix this, you can try scanning your PC with an antivirus or anti-malware software like Windows Defender or Malwarebytes. You can also try updating your Windows, BIOS, and firmware to the latest version. You can also try performing a system restore or a clean install of Windows to remove any potential software issues.
  • These

are some of the most common causes and solutions for the problem of losing display and ramping up the fans after running your PC for a while. However, there may be other factors that are specific to your PC or situation. Therefore, it is recommended that you consult a professional technician or a reputable online forum for further assistance. We hope this article was helpful and informative. Thank you for reading.
