Top 10 Common Computer Problems and How to Fix Them

1. Slow Performance

A common complaint among computer users is slow performance, which can be frustrating and hinder productivity. Several factors contribute to this issue, including insufficient RAM, too many background processes, or a fragmented hard drive.

DIY Fixes:

1. Increase RAM: Upgrading your computer’s RAM can significantly boost its performance. Check your computer’s specifications to see the maximum RAM capacity and purchase compatible memory sticks.
2. Close Background Processes: Open Task Manager (Ctrl + Shift + Esc) and end unnecessary tasks that consume resources.
3. Defragment Hard Drive: For older systems with HDDs, use the built-in Disk Defragmenter tool to organise data and improve speed.
4. Check what the storage device is on your computer, if it is an HDD then you might want to get it upgraded to an SSD, by upgrading to an SSD you can speed up your computer by at least X20 times if not more.

When to Seek Help:

If your computer remains slow despite these efforts, the problem might be more complex, such as a failing hard drive or a malware infection. Auckland Geeks once helped a client whose laptop had slowed down drastically. Upon inspection, they found a hidden cryptocurrency mining malware causing the slowdown. Professional intervention ensured the malware was removed, and the laptop was restored to optimal performance.

2. Software Crashes

Software crashes can disrupt work and result in data loss. They often occur due to incompatible software, outdated drivers, or corrupted files.

DIY Fixes:

1. Update Software and Drivers: Ensure all your software and drivers are up-to-date. Check for updates regularly and install them.
2. Reinstall Problematic Software: Uninstall the software causing crashes and reinstall it to fix corrupted files.
3. Run System File Checker: Use the System File Checker tool (sfc /scannow) to repair corrupted system files.

When to Seek Help:

If crashes persist, it might indicate deeper issues such as hardware conflicts or severe software corruption. Auckland Geeks encountered a case where a client’s design software repeatedly crashed. The problem was traced to an outdated graphics driver that was incompatible with the latest software update. Updating the driver resolved the issue, allowing the client to resume work without interruptions.

3. Overheating

Overheating can cause significant damage to computer components and lead to unexpected shutdowns. Dust build-up, poor ventilation, and malfunctioning cooling systems are common causes.

DIY Fixes:

1. Clean the Computer: Use compressed air to clean dust from vents, fans, and heat sinks.
2. Improve Ventilation: Ensure your computer is placed in a well-ventilated area. Avoid placing it on soft surfaces like beds or couches that can block airflow.
3. Replace Thermal Paste: For more experienced users, replacing the thermal paste on the CPU can improve heat transfer and cooling efficiency.

When to Seek Help:

Persistent overheating issues may require professional assessment. Auckland Geeks once helped a client with a desktop that repeatedly shut down due to overheating. The problem was traced to a failing CPU fan. Replacing the fan and cleaning the internal components solved the issue, ensuring the computer ran smoothly and safely.

4. Blue Screen of Death (BSOD)

The Blue Screen of Death is a dreaded error screen indicating a critical system failure. It can be caused by hardware issues, driver problems, or corrupted software.

DIY Fixes:

1. Update Drivers: Ensure all hardware drivers are current.
2. Check for Hardware Issues: Use built-in tools like Windows Memory Diagnostic to check for RAM issues.
3. Scan for Malware: Run a full system scan with your antivirus software to rule out malware as a cause.

When to Seek Help:

Recurring BSODs can indicate serious hardware or software problems. Auckland Geeks once assisted a client whose computer frequently displayed BSOD errors. A thorough diagnostic revealed a failing hard drive. Replacing the hard drive and reinstalling the operating system resolved the issue, restoring the system’s stability.

5. Internet Connectivity Issues

Internet connectivity problems can stem from various sources, including faulty hardware, incorrect settings, or ISP issues.

DIY Fixes:

1. Check Hardware: Ensure your modem and router are functioning correctly. Restart them if necessary.
2. Update Network Drivers: Outdated network drivers can cause connectivity issues. Update them through the Device Manager.
3. Reset Network Settings: On Windows, use the Network Reset tool to restore default network settings.

When to Seek Help:

If these steps don’t resolve the issue, professional assistance may be needed to diagnose and fix the problem. Auckland Geeks once helped a small business experiencing frequent internet drops. After a thorough investigation, they identified and replaced a faulty router, ensuring a stable and reliable internet connection for the business.

6. Unresponsive Programs

Sometimes, programs may become unresponsive, leading to frustration and potential data loss. This can be caused by insufficient system resources or software conflicts.

DIY Fixes:

1. Increase Virtual Memory: Adjust your system’s virtual memory settings to provide additional resources for programs.
2. Close Unnecessary Programs: Free up system resources by closing unused applications.
3. Run Compatibility Troubleshooter: Use Windows’ built-in compatibility troubleshooter to fix software conflicts.

When to Seek Help:

If programs frequently become unresponsive, it might indicate deeper system issues. Auckland Geeks once assisted a client whose accounting software regularly froze. The problem was traced to a background process consuming excessive memory. Optimising system resources and upgrading the client’s RAM resolved the issue, allowing the software to run smoothly.

7. Printer Issues

Printer problems are common and can be frustrating, especially when you need to print something urgently. These issues can arise from connectivity problems, outdated drivers, or configuration errors.

DIY Fixes:

1. Check Connections: Ensure the printer is correctly connected to the computer and powered on.
2. Update Printer Drivers: Download and install the latest drivers from the printer manufacturer’s website.
3. Run Printer Troubleshooter: Use Windows’ built-in printer troubleshooter to identify and fix common issues.

When to Seek Help:

If printer problems persist, professional diagnosis might be needed. Auckland Geeks once helped a client whose printer consistently failed to print. The issue was traced to an outdated driver and incorrect network settings. Updating the driver and reconfiguring the printer’s network settings resolved the problem, restoring its functionality.

8. Frozen Screen

A frozen screen can halt all activity on your computer, often requiring a restart. This issue can be caused by hardware problems, software conflicts, or overheating.

DIY Fixes:

1. Force Restart: If the screen is completely unresponsive, perform a hard reset by holding down the power button.
2. Update Software and Drivers: Ensure all your software and drivers are up-to-date.
