Computers are incredible tools—until they suddenly stop working the way they should. Whether you’re dealing with a slow PC, strange pop-ups, or a system that refuses to turn on, many common computer issues have simple solutions you can try at home before calling a technician.
Here are 10 common computer problems and how to fix them.

Disable unnecessary startup apps
-
Run a full antivirus scan
-
Restart your computer regularly
-
Upgrade RAM or switch to an SSD if the system is outdated

How to Fix It:
-

-
Try another power outlet

Remove and reconnect the battery (laptops)

Listen for beeps or lights — they can indicate specific hardware issues
-
If nothing works, the power supply or motherboard may need professional repair

Update the software to the latest version
-
Check for insufficient RAM
