Troubleshooting PC Crashes Under Load: What You Need to Know


What could be causing my PC to crash under load, even after replacing the GPU and reinstalling Windows?

This question is more concise and clear, and it specifies the actions you have already taken to troubleshoot the problem. It also invites the expert to provide possible explanations and solutions for your issue.


If your PC crashes under load, it means that something is not working properly when your system is handling demanding tasks, such as gaming, video editing, or rendering. This can be frustrating and annoying, especially if you have already tried replacing the GPU and reinstalling Windows, which are common solutions for many PC issues.

There are several possible causes for PC crashes under load, and they can be related to hardware, software, or both. Some of the most common ones are:

  • Overheating: Overheating can result in system crashes, as your PC tries to protect itself from damage. Ensure your PC’s fans and cooling system function properly, and clean any dust build-up. Check your CPU and GPU temperatures using a monitoring tool, and if they’re consistently high, consider upgrading your cooling solution.
  • Power supply: A faulty or insufficient power supply can also cause PC crashes under load, as your system may not receive enough power to run smoothly. Check the wattage and efficiency of your power supply, and make sure it can handle your PC’s components, especially the GPU. If possible, test your PC with a different power supply, or use a power supply tester to check for any issues.
  • Memory: Bad or incompatible memory modules can also lead to PC crashes under load, as your system may encounter errors or corruption when accessing data. Run a memory diagnostic tool to check for any errors, and make sure your memory modules are properly seated and compatible with your motherboard. You can also try swapping or removing memory modules to isolate the problem.
  • Drivers: Outdated or corrupted drivers can also cause PC crashes under load, as your system may not communicate well with your hardware devices. Make sure you have the latest drivers for your GPU, chipset, audio, and other components, and uninstall any unnecessary or conflicting drivers. You can use Windows Update or a driver updater tool to check for driver updates.
  • Malware: Malware and other security threats can also cause system crashes, as they may interfere with your system’s performance or stability. To rule out this possibility, run a thorough antivirus scan using Windows Defender or a trusted third-party antivirus solution. To perform a full scan with Windows Defender, open the Windows Security app, click on Virus & Threat Protection, and under Scan Options, choose Full Scan.
  • These are some of the most common causes for PC crashes under load, but there may be other factors involved, such as BIOS settings, overclocking, or hardware compatibility. To further diagnose and troubleshoot the issue, you can also use the Windows Event Viewer, which logs system events and errors, and can help you identify the source of the problem. You can also check online forums or contact a professional for more assistance.
