Identifying PC Boot Loop

TODO: collapasable, copyable, download, etc

I have a PC tower and it stopped working. When I power it on, it makes some noise and some fans turn on. Then the fans slow. Then it starts the process again. I never see the bios on the monitor. The monitor is never woken up. What is the best way to step by step identify the issue?It sounds like your PC is experiencing a boot loop, which can be caused by a variety of issues. Here's a step-by-step approach to identify and potentially resolve the issue:

1. Check Power Supply Unit (PSU):

   • Ensure the PSU is properly connected to the motherboard and all components.
   • If possible, test with another known working PSU to rule out a faulty PSU.

2. Inspect Motherboard Connections:

   • Check that all cables and components are securely connected to the motherboard, including the 24-pin power connector, CPU power connector, and any GPU power connectors.
   • Reseat components like RAM and graphics card to ensure a proper connection.

3. Check RAM:

   • Remove all RAM sticks and try booting with one stick at a time in different slots to identify a potential faulty RAM stick or slot.

4. Monitor and Graphics Card:

   • Ensure the monitor is working by connecting it to another device.
   • If using a dedicated graphics card, ensure it's properly seated and powered. Try reseating it or, if possible, test with another graphics card.
   • If your motherboard has integrated graphics, try removing the dedicated GPU and connecting the monitor to the motherboard’s display output.

5. Check for BIOS/CMOS Issues:

   • Clear the CMOS to reset the BIOS settings to default. This can be done by removing the CMOS battery for a few minutes or using the clear CMOS jumper on the motherboard.

6. Inspect CPU and Cooler:

   • Ensure the CPU is properly seated and the CPU cooler is properly attached.
   • Check for any bent pins on the CPU or socket.

7. Listen for Beep Codes:

   • If your motherboard has a speaker, listen for beep codes during startup. These codes can help identify specific hardware issues.

8. Minimal Boot:

   • Try booting with the minimum hardware necessary (CPU, one stick of RAM, PSU). Disconnect all non-essential hardware (storage drives, peripherals, additional PCIe cards).

9. Check Storage Devices:

   • Ensure that your primary storage device (HDD/SSD) with the operating system is properly connected and recognized in the BIOS (if you can get to the BIOS).

10. External Factors:

    • Check for any signs of physical damage or electrical short circuits on the motherboard and other components.
    • Consider environmental factors like power surges or recent electrical work in your area.

11. Professional Help:

    • If you're unable to resolve the issue, it might be best to seek professional help. Sometimes the problem could be a deeper hardware failure that requires specialized equipment and knowledge to diagnose.

Remember, while troubleshooting, handle components with care and ensure you're grounded to prevent static damage. If you're not comfortable performing any of these steps, it's best to consult with a professional technician.I held down the delete key while booting. This said it cleared CMOS and booted into the bios screen. I then pushed F7 to load in optimized defaults. the PC rebooted and worked. WHy?Clearing the CMOS and loading optimized defaults in the BIOS can resolve various PC boot issues for several reasons:

1. Resetting BIOS Settings: Over time, BIOS settings can become corrupted or misconfigured, either due to user changes, software conflicts, or hardware issues. Resetting the BIOS to its default settings ensures that any incorrect configurations are cleared out.

2. Hardware Compatibility: Sometimes, hardware components may not function correctly due to specific BIOS settings. Resetting to defaults ensures that all settings are at their most compatible and basic levels, often resolving compatibility issues.

3. Overclocking Issues: If your system was overclocked, this can sometimes lead to instability and boot problems. Resetting the BIOS defaults will remove any overclocking settings, potentially resolving these issues.

4. Updating BIOS Memory: The CMOS (Complementary Metal-Oxide Semiconductor) stores BIOS settings, and clearing it forces the system to rebuild and update its information. This process can resolve issues where the BIOS was not properly recognizing hardware or settings.

5. Resolving Conflict with New Hardware: If new hardware was added to the system, it might not have been compatible with the existing BIOS settings. Resetting to defaults can help the BIOS correctly identify and work with the new hardware.

6. Power Management Errors: Modern BIOS/UEFI firmware includes various power management settings that, if misconfigured, can cause boot issues. Resetting to defaults ensures these settings are at their most stable configurations.

In summary, clearing the CMOS and loading optimized defaults acts as a "reset" for your system's firmware, eliminating any misconfigurations or corruptions that might have been preventing a successful boot. It's a common and effective first step in troubleshooting various computer startup issues.Why are Apple computers more reliable than windows PCs?The perception that Apple computers are more reliable than Windows PCs can be attributed to several factors, but it's important to note that "reliability" can be subjective and depends on various aspects such as hardware quality, software stability, user experience, and personal preferences. Here are some reasons why Apple computers might be seen as more reliable:

1. Integrated Hardware and Software: Apple controls both the hardware and software of its computers. This tight integration allows for optimized performance and stability since the operating system and applications are designed specifically for the hardware they run on.

2. Quality Control: Apple is known for its high standards in design and manufacturing. The company's focus on a limited range of products allows for more stringent quality control, potentially leading to more reliable hardware.

3. Operating System Stability: macOS is built on a Unix-based foundation, which is known for its stability and security. This can contribute to a more reliable and consistent user experience.

4. Less Prone to Viruses and Malware: Historically, macOS has been less targeted by viruses and malware compared to Windows, partly due to its smaller market share and its Unix-based architecture. This can lead to a perception of greater reliability and security.

5. Software Updates: Apple provides regular software updates that are generally seen as stable and reliable. These updates are available to all compatible devices simultaneously, ensuring that most users have the latest, most secure version.

6. Limited and Controlled Ecosystem: Apple’s ecosystem is more controlled compared to the vast and diverse Windows ecosystem. This means less variability in hardware and software configurations, which can lead to fewer compatibility issues.

7. Customer Service and Support: Apple’s customer service, including its physical Apple Stores and the Genius Bar, is often highly rated. Easy access to support and service can enhance the user experience and perception of reliability.

However, it's important to acknowledge that Windows PCs also have their strengths:

• Diverse Hardware Ecosystem: The Windows platform supports a vast array of hardware from different manufacturers, allowing for more choice in terms of specifications, design, and price points.
• Flexibility and Customizability: Windows PCs offer more options for customization and upgrading individual components.
• Software Compatibility: Windows has a broad software ecosystem, supporting a wide range of applications, including many enterprise and gaming applications.

Ultimately, whether Apple computers are more reliable than Windows PCs can depend greatly on individual needs, usage patterns, and preferences. Both platforms have their advantages and loyal user bases.
