7 Common Computer Errors Every DIY Computer Builder Should Know

Building your own computer can be an exciting and fulfilling experience. It allows you to customize your machine to meet your specific needs and preferences. However, DIY computer building is not without its challenges. From software glitches to hardware compatibility issues, there are several common errors that every DIY computer builder should be aware of.

In this blog post, we will explore seven common computer errors that can occur during the building process. By understanding these errors and learning how to troubleshoot them, you can save yourself time, money, and frustration. Whether you’re a seasoned DIY builder or just starting out, this guide will provide you with valuable insights to help you overcome these computer errors and ensure a smooth building process.

Blue Screen of Death (BSOD)

The Blue Screen of Death (BSOD) is an error screen that appears when a critical system error occurs in Windows. It is often accompanied by a blue screen with white text, hence the name. The BSOD can be caused by various factors, including hardware compatibility issues, driver conflicts, or faulty RAM.

To troubleshoot BSOD errors, start by identifying any recent hardware or software changes you made to your system. If you recently installed new hardware, ensure that it is compatible with your motherboard and other components. Update your drivers to the latest versions, as outdated drivers can cause conflicts and crashes. Additionally, run a memory diagnostic test to check for any faulty RAM modules.

If the BSOD error persists, try booting into Safe Mode to isolate any software-related issues. You can do this by restarting your computer and pressing the F8 key repeatedly until you see the Advanced Boot Options menu. From there, select Safe Mode and see if the BSOD error occurs again. If it doesn’t, it indicates that a third-party driver or software is causing the issue.

Overheating Issues

Overheating can significantly impact a computer’s performance and longevity. When a computer gets too hot, it can lead to system instability, sudden shutdowns, and even permanent damage to components. Common causes of overheating include inadequate cooling systems, improper airflow, or dust accumulation in the case.

To prevent overheating, ensure that your computer has proper cooling in place. This includes installing sufficient fans and a CPU cooler. Make sure that your case has adequate airflow by positioning fans strategically and keeping cable management tidy. Regularly clean the dust from your computer’s components using compressed air or an antistatic brush.

If you’re already facing overheating issues, check if your fans are spinning properly and if they’re clogged with dust. Consider reapplying thermal paste on your CPU if it’s been a while since you last did so. You may also want to monitor your computer’s temperature using software utilities to pinpoint specific components that are running hot.

Booting Problems

Booting problems can be frustrating as they prevent your computer from starting up properly. There are several booting issues that DIY builders commonly encounter, such as “Boot Device Not Found,” “Operating System Not Found,” and “Disk Boot Failure.”

If you encounter a “Boot Device Not Found” error, it may indicate that your computer is unable to detect the bootable drive. Check if the drive is properly connected and recognized in the BIOS settings. If necessary, change the boot order in the BIOS to ensure that the correct drive is set as the primary boot device.

An “Operating System Not Found” error typically occurs when there is an issue with your operating system installation or configuration. Ensure that your operating system is installed correctly and that the boot partition is active. If necessary, use a bootable USB or DVD to repair or reinstall your operating system.

A “Disk Boot Failure” error can be caused by various factors, such as a faulty hard drive or incorrect BIOS settings. Check if your hard drive is properly connected and recognized by the system. Verify that the boot order in the BIOS is correctly set to prioritize the hard drive as the first boot device.

Memory Errors

RAM plays a crucial role in a computer’s performance and stability. Memory-related errors like “Memory Management” or “Page Fault in Nonpaged Area” can occur due to faulty RAM modules or incorrect memory settings.

To diagnose memory errors, start by running a memory diagnostic test. Windows has a built-in tool called Windows Memory Diagnostics that can help identify any issues with your RAM. If errors are detected, try reseating your RAM modules to ensure they are properly inserted into their slots.

If reseating doesn’t resolve the issue, try testing each RAM module individually to identify any faulty ones. Replace any faulty modules with compatible replacements. Additionally, ensure that your RAM modules are running at their correct speeds and timings by checking the BIOS settings.

Hard Drive Failures

Hard drive failures can result in data loss and system instability. There are two main types of hard drive failures: physical failures and logical failures.

Physical failures occur when there is a mechanical issue with the hard drive itself, such as a damaged read/write head or platter. Symptoms of physical hard drive failures include clicking noises, slow performance, and failure to be detected by the system. In such cases, professional data recovery services may be required to retrieve your data.

Logical failures, on the other hand, occur when there is a software or firmware issue with the hard drive. This can result in data corruption or an inability to access data on the drive. In such cases, you may be able to recover your data using data recovery software or by connecting the drive to another computer as a secondary storage device.

To prevent future hard drive failures, make sure to back up your important data regularly. Consider using cloud storage services or external hard drives for backups. Additionally, avoid moving your computer while it’s powered on to minimize the risk of physical damage to the hard drive.

Graphics Card Issues

Graphics card issues can manifest in various ways, such as display driver crashes, graphical artifacts on the screen, or poor gaming performance. Common causes of graphics card errors include outdated drivers, overheating, or hardware incompatibility.

To address graphics card issues, start by updating your graphics card drivers to the latest version available from the manufacturer’s website. Outdated drivers can cause stability issues and poor performance. Consider using driver update software or utilities like Driver Booster or GeForce Experience to simplify the driver update process.

Ensure that your graphics card is not overheating by monitoring its temperature using software utilities like MSI Afterburner or GPU-Z. If temperatures are too high, consider cleaning any dust from the graphics card’s heatsink and fans or adjusting fan curve settings for better cooling.

If you’re experiencing graphical artifacts on the screen, try reseating the graphics card into its slot or connecting it to a different PCIe slot if available. Ensure that all power connectors are properly connected to the graphics card.

Power Supply Problems

A reliable power supply unit (PSU) is crucial for providing stable power to your components. Power supply problems can manifest in various ways, such as random shutdowns, failure to power on, or unstable performance.

If you’re experiencing random shutdowns or failure to power on, check if all power connectors are properly connected to your components. Ensure that the PSU’s power switch is turned on and that it’s receiving power from the wall outlet.

If you suspect a faulty PSU, consider using a PSU tester or swapping it out with another known-working PSU to rule out any power supply-related issues.


In conclusion, understanding common computer errors is essential for DIY builders to ensure a successful build. By familiarizing yourself with these errors and learning how to troubleshoot them effectively, you can save time, money, and frustration during the building process.

Remember to stay updated on the latest troubleshooting techniques and seek professional help when needed. Building your own computer is an empowering experience, and with the knowledge gained from this comprehensive guide, you’ll be well-equipped to tackle common computer errors and enjoy a smooth building process.
