Top 5 Common Computer Problems and How to Fix Them

Computers have become a vital part of modern life as we use them for work, study, communication, and entertainment. But even the most reliable machines can develop issues over time. From slow performance to network failures, computer problems can disrupt your daily routine and productivity.

Understanding the most common issues can help you identify and resolve them quickly. And when things get too complicated, trusted professionals like Star Tech Service are always ready to assist.

When Your Computer Starts to Slow Down

A slow computer is one of the most common and frustrating problems users face. Over time, your system may begin to lag, programs take longer to open, startup feels endless, and simple tasks become a struggle.

This can happen for several reasons: too many background applications, limited storage space, outdated software, or even malware. To fix this, start by cleaning up your system. Disable unnecessary startup programs, uninstall unused apps, and delete temporary files. For a major performance boost, consider upgrading to a solid-state drive (SSD) or adding more RAM.

Star Tech’s service experts can also perform professional system maintenance, including cleanup, optimization, and hardware upgrades, to make your PC run like new again.

When the Computer Won’t Turn On

Few issues are more worrying than pressing the power button and seeing nothing happen. Sometimes, the solution is as simple as checking the power cable or battery connection. However, if your computer still won’t turn on, the problem might involve the power supply, motherboard, or other internal components.

It’s best not to open the device unless you have experience with computer hardware. Instead, take it to a certified technician. Star Tech’s skilled service team can diagnose power-related problems safely and efficiently, replacing or repairing faulty parts when needed.

Dealing with Viruses and Pop-ups

If you’re constantly bombarded by unwanted pop-ups or strange software installing itself, your system may be infected with malware. These infections not only slow down your computer but can also compromise your personal data.

Running a full antivirus scan is the first step to cleaning up your system. Removing suspicious browser extensions and resetting browser settings can also help. However, if the problem persists, it’s wise to get a professional malware removal service.

At Star Tech Service, our technicians use advanced tools to remove even the most stubborn viruses, ensuring your system is fully protected and performing at its best.

Overheating and Loud Fans

Excessive heat is another frequent computer problem. Overheating can cause your computer to slow down, freeze, or even shut down unexpectedly. The most common causes are dust buildup and blocked air vents.

Regularly cleaning your computer’s cooling system is essential. You can use compressed air to remove dust and make sure your device has enough airflow. If your system continues to overheat, it might need a professional cleaning or thermal paste replacement. Star Tech’s repair team provides deep cleaning and thermal maintenance services to help prevent long-term hardware damage.

Internet Connection Problems

A poor or unreliable internet connection can disrupt both work and leisure. The issue might come from your router, network drivers, or DNS settings.

To troubleshoot, restart your router and PC, and use Windows’ built-in network troubleshooter. Updating your network drivers and flushing the DNS cache can also help. If your connection remains unstable, you may need professional assistance to test your network hardware or settings.

Star Tech’s network and connectivity specialists can quickly identify and resolve connection issues, whether at home or in the office, ensuring smooth, uninterrupted performance.

Final Thoughts

While many computer problems can be fixed at home with a little patience and basic knowledge, some require expert care. Regular maintenance not only keeps your computer performing well but also prevents costly repairs in the future.

If your device is showing signs of trouble, from slow speed to hardware failure, you can trust Star Tech Service, one of Bangladesh’s most reliable computer service providers.
