Fix Random Restarts During Gaming or Video Playback

Introduction

If your CLX PC randomly restarts while watching videos or playing games, this guide can help you isolate the cause and try the most common fixes. Random restarts are often related to graphics drivers, GPU seating, power delivery, or hardware stability under load.

Issue description

This issue occurs when the system powers off and restarts unexpectedly during graphics-intensive tasks such as video playback, gaming, or other GPU-heavy workloads. In many cases, the restart happens without a warning message or blue screen.

Signs

• The PC restarts only when watching videos or launching games.
• The restart happens more often under heavy GPU load.
• The system may be stable during light desktop use but unstable during graphics-intensive tasks.
• The restart may happen with no error message or warning.

Basic troubleshooting steps

Start with these checks before moving to more advanced diagnostics.

• Update your graphics drivers to the latest version from the GPU manufacturer.
• Restart the PC after installing driver updates.
• Check that all power cables are fully seated, including GPU power connectors.
• Make sure the system is not overheating during gaming or video playback.
• Remove any recent software or hardware changes that may have introduced instability.

Advanced troubleshooting steps

Step 1: Reinstall or update the graphics drivers

If the drivers are outdated or possibly corrupted, reinstalling them can resolve random restarts. Use the latest stable driver version for your GPU, then test the system again with the same video or game that caused the restart.

Step 2: Reseat the GPU in a different PCIe slot

If the issue continues, power down the system and move the GPU to a different PCIe slot if your motherboard supports it. This can help identify a slot-related connection issue or motherboard instability.

Step 3: Test the system without the GPU inserted

To isolate the problem, perform intensive tasks without the GPU inserted if your system supports integrated graphics. If the restarts stop, the GPU, its power delivery, or the PCIe path may be involved.

Contact support

If the restarts continue after updating drivers and testing the GPU, contact CLX Support for further troubleshooting. Be prepared to share your system model, GPU model, driver version, and a description of when the restart occurs.

Additional resources

For faster diagnosis, gather any relevant system logs, note the exact game or video app you were using, and record whether the restart happens at startup, during playback, or under load.

Conclusion

Random restarts during gaming or video playback are often caused by graphics driver issues or GPU-related hardware problems. Updating drivers, testing a different PCIe slot, and isolating the GPU are the most effective next steps to narrow down the cause.
