Solution Steps
- 1 Check CPU temperature: Download a temperature monitoring tool like Core Temp or HWMonitor. If temperatures exceed 90°C under load, your CPU may be overheating. Clean dust from fans and ensure proper airflow.
- 2 Reset BIOS to default settings: Restart your PC and press the key to enter BIOS (often Del, F2, or F10). Look for an option to 'Load Optimized Defaults' or 'Reset to Default'. Save and exit. This will undo any overclocking or unstable settings.
- 3 If you have overclocked your CPU, revert to stock settings. In BIOS, set the CPU multiplier and voltage to auto or default. Overclocking can cause instability if not done properly.
- 4 Update your BIOS: Visit your motherboard manufacturer's website and download the latest BIOS update. Follow their instructions to flash it. An outdated BIOS can have bugs that cause this error.
- 5 Check your power supply: Ensure your power supply unit (PSU) has enough wattage for your system. A failing or insufficient PSU can cause voltage drops, leading to this error. Consider testing with a known good PSU if possible.
- 6 Run a CPU stress test: Use a tool like Prime95 to stress the CPU. If the BSOD occurs during the test, it's likely a hardware issue. Monitor temperatures and voltages during the test.
