    Hello,

    Thank you for posting in Microsoft Q&A.

    Based on the description, I understand your question is related to red light blinking on CPU.

    There are several possibilities of red light blinking: The CPU might be overheating due to inadequate cooling. There could be loose or improperly connected components. Issues with the CPU, RAM, or other hardware components. Corrupt or outdated BIOS settings. Insufficient or unstable power supply.

    Try check the CPU fan is working properly and is securely connected, all cables and components are properly connected. Remove and reinsert the RAM, GPU, and other components to ensure they are seated correctly. Check the cooling system is functioning and there is no dust buildup, power supply unit (PSU) is providing adequate power.

    Have a nice day.

    Best Regards,

    Molly
