Reasons Why BIOS Doesn’t Start and Tips for Fixing It

1. Check Power and Connections: Ensure that everything is plugged in properly and that there is power to the system. Verify that the CPU fan is spinning and the power supply is functioning.

2. Reset BIOS Settings: Try resetting the BIOS to its default settings using the BIOS Reset Jumper on the motherboard. This can help resolve any configuration issues that may be preventing the BIOS from starting.

3. Update BIOS: Consider updating the BIOS to the latest version. This can improve system functionality and fix compatibility issues. Download the BIOS update from the manufacturer’s website and follow their instructions carefully.

4. Check Hardware: Inspect components like the graphics card, RAM, and motherboard. Ensure they are properly installed and functioning correctly. Try removing and reseating them if necessary.

5. Troubleshoot Software: If you recently installed any new programs or made changes to the system, try booting into safe mode or using the Windows boot menu to remove or disable them. This can help identify software conflicts.

Alternative Method to Access BIOS

If your PC is not starting, and you’re unable to access the BIOS or see any display, there are alternative methods to try.

First, make sure everything is properly connected inside the tower, including the graphics card and RAM. Then, check if your power supply is functioning correctly.

To access the BIOS, try using BIOS Reset Jumper on your mainboard. If that doesn’t work, you can also try using a USB stick with a BIOS update or accessing the Windows Boot Menu.

Additional Cause of BIOS Startup Failure: Graphics Card

If your PC is not starting up and you are not getting any display (Bild), it could be due to a problem with your graphics card. Here are some tips to troubleshoot this issue:

1. Check the connection: Make sure the graphics card is properly seated in the PCIe slot on the motherboard (Mainbord).

2. Power supply: Ensure that the graphics card is receiving enough power from the PSU (Netzteil). Check if all power connectors are securely connected.

3. Update BIOS: Sometimes, updating the BIOS (UEFI) can resolve compatibility issues between the graphics card and the motherboard.

4. Disable integrated graphics: If your CPU has integrated graphics, try disabling it in the BIOS (UEFI) settings. This can help prioritize the dedicated graphics card.

python import subprocess


def check_bios_boot_failure():

    # Check if the PC is powered on and connected properly

    power_status = subprocess.run(["power_status_check_command"], capture_output=True).stdout.decode().strip()

    if power_status != "ON":

        return "PC is not powered on or not properly connected."
    # Check if the BIOS is accessible

    bios_accessibility = subprocess.run(["bios_access_check_command"], capture_output=True).stdout.decode().strip()

    if bios_accessibility != "OK":

        return "Unable to access the BIOS."
    # Check for any hardware issues preventing booting

    hardware_status = subprocess.run(["hardware_status_check_command"], capture_output=True).stdout.decode().strip()

    if hardware_status != "OK":

        return f"Hardware issue detected: {hardware_status}"
    # Check for any software issues preventing booting

    software_status = subprocess.run(["software_status_check_command"], capture_output=True).stdout.decode().strip()

    if software_status != "OK":

        return f"Software issue detected: {software_status}"
    return "No boot failure issues detected."

# Example usage result = check_bios_boot_failure() print(result)

Understanding PCIe*, UEFI, and Data Storage

An article titled: PC startet nicht, kein BIOS, kein Bild.

Term	Description
PCIe*	PCIe (Peripheral Component Interconnect Express) is a high-speed serial computer expansion bus standard used to connect various hardware devices such as graphics cards, sound cards, and network cards to the motherboard of a computer. It provides faster data transfer rates and improved performance compared to older bus standards.
UEFI	UEFI (Unified Extensible Firmware Interface) is a modern firmware interface that replaces the traditional BIOS (Basic Input/Output System) in computers. It provides a more advanced and flexible interface for initializing the hardware components during the boot process and allows for additional features such as secure boot, faster startup times, and support for larger storage devices.
Data Storage	Data storage refers to the process of storing and retrieving data on various storage devices such as hard disk drives (HDDs), solid-state drives (SSDs), and external storage devices. It involves organizing and preserving digital information for future use, ensuring data integrity, and providing quick access to stored data when needed.
