Computer Black Screens with all fans running at 100%, seemingly random. Otherwise it works fine?

Replace your CMOS battery

Hi Welcome to Microsoft community. The issue you're describing—where your computer experiences a black screen and all fans run at 100%—is commonly associated with hardware problems, particularly with the GPU. The error codes from the Windows Reliability Monitor (LiveKernelEvent codes 117, 141, and 144) further suggest that your GPU or its drivers might be causing these crashes. Here are some steps to diagnose and potentially resolve the issue: 1. Check GPU DriversYou've already reinstalled your GPU drivers, which is a good step. Ensure that you performed a clean installation of the drivers:

• Use a tool like Display Driver Uninstaller (DDU) to completely remove existing drivers.
• Download and install the latest drivers directly from the NVIDIA website.
• Disclaimer: This is a non-Microsoft website. The page appears to be providing accurate and safe information. Watch out for ads on the site that may advertise products frequently classified as PUP (Potentially Unwanted Products). Thoroughly research any product advertised on the site before you decide to download and install it.

2. Monitor TemperaturesOverheating can cause the symptoms you're experiencing. Use a tool to monitor the temperatures of your CPU and GPU. Ensure that they are within safe operating ranges:

• Idle temperatures: CPU (30-45°C), GPU (30-40°C)
• Load temperatures: CPU (60-80°C), GPU (60-85°C)

3. Check PSU (Power Supply Unit) A failing or inadequate PSU can cause instability, especially under load (e.g., while gaming). Ensure that your PSU is providing sufficient power for your components. If possible, test with a different PSU. 4. Run Hardware Diagnostics

• Memory: Use a tool to check for RAM errors.
• GPU: Use a tool to stress test your GPU. Monitor temperatures and stability during the test.

5. Check for Hardware Issues

• Reseat Components: Ensure that your GPU, RAM, and other components are securely seated in their slots.
• Inspect for Physical Damage: Check for any visible damage on the motherboard, GPU, or other components.
• Test with Another GPU: If you have access to another GPU, swap it in to see if the issue persists.

6. Update BIOS and Chipset Drivers Ensure your motherboard BIOS and chipset drivers are up to date. Visit your motherboard manufacturer's website to download the latest versions.

If you are going to modify BIOS Settings, please back up all your personal files first to ensure you do not lose data. 7. Check for Software ConflictsSome of the drivers mentioned in your minidump (e.g., athw8x.sys, mbam.sys, farflt.sys, mbae64.sys) are associated with various software like network drivers and security software (Malwarebytes). Ensure that these are up to date and not conflicting with your system:

• Update or temporarily uninstall security software to see if the issue persists.

8. Test Stability with Default Settings If you have overclocked your CPU, GPU, or RAM, revert them to their default settings to see if stability improves. 9. System Restore or Windows ReinstallationIf the issue persists, consider performing a system restore to a point before the crashes started occurring. As a last resort, a clean installation of Windows can help rule out software issues. Let me know if you need further assistance. Best regardsDerrick Qian | Microsoft Community Support Specialist
