5 Common Computer Problems and Fixes

If you use a PC or Mac, chances are you’ve run into a few common computer problems over the years. Slow speed, freezing screens, stubborn printers — these issues can make you feel like tossing your computer out the window. But don’t panic! The good news is most common computer problems have simple fixes you can try at home before calling in a professional.

In this post, I’ll walk you through 5 of the most common computer problems and fixes I see every day, plus a few bonus tips to keep your system running smoothly.

1. My Computer Is So Slow

One of the most common computer complaints is slow performance. Over time, programs pile up, temporary files collect dust, and background apps hog memory.

Fixes to try:

• Restart your computer to clear out memory and refresh processes.

• Check the Task Manager (Windows) or Activity Monitor (Mac) to see if programs you don’t use are eating up resources.

• Uninstall apps you don’t need.

If your computer is still crawling, a tune-up can breathe new life into it.

2. My Printer Won’t Work

Few things cause as much frustration as a printer that refuses to cooperate. This is another one of the most common computer problems I help people with.

Fixes to try:

• Double-check that the printer is plugged in and has paper.

• If it’s wireless, make sure your computer and printer are on the same Wi-Fi network.

• Turn it off, unplug for 30 seconds, and restart.

Still not printing? It may be a driver issue, which is something I can help with remotely.

3. I Keep Getting Strange Pop-Ups

Pop-ups can be harmless ads, but sometimes they’re signs of malware or adware. Left unchecked, they can make your computer almost unusable.

Fixes to try:

• Run a full antivirus or anti-malware scan.

• Never click on pop-ups asking for personal or financial information.

• Consider using a trusted ad-blocker.

If the pop-ups keep coming back, it’s time for professional cleanup.

4. My Computer Won’t Turn On

Nothing feels worse than pressing the power button and getting a black screen. This is one of the scariest common computer problems — but often, the fix is simple.

Fixes to try:

• Check that the power cable is securely connected.

• Try a different outlet or power strip.

• If it’s a laptop, make sure the charger is working.

If none of these work, the issue might be with the hardware or motherboard.

5. I Think I Have a Virus

Viruses and malware are unfortunately still common computer problems in 2025. They can slow down your system, cause pop-ups, or even steal information.

Fixes to try:

• Disconnect from the internet immediately.

• Run a full scan with an updated antivirus program.

• Avoid downloading programs from untrusted sources.

If your system still acts strange, it’s best to get expert help quickly.

Bonus Tips to Prevent Common Computer Problems

• Restart your computer at least once a week.

• Keep your software and operating system updated.

• Run regular virus and malware scans.

• Back up your files so you’re protected against crashes.

Frequently Asked Questions About Computer Problems

What’s the most common computer problem?
The most common issue I see is slow performance, usually from too many programs running or lack of regular maintenance.

Should I repair or replace my computer?
If your computer is more than 7–8 years old and repairs cost more than half the price of a new one, replacement may make more sense. But often, a simple tune-up keeps an older PC running almost like new.

How often should I tune up my computer?
Think of it like a car — a tune-up once or twice a year keeps things running smoothly and helps prevent bigger problems down the road.

Computer problems are stressful, but they don’t have to ruin your day. By knowing the most common computer problems and fixes, you can often solve issues yourself and keep your system working longer.
