A slow computer does not always mean it is broken. Often the cause is too many startup apps, low storage, pending updates, a busy browser or an app using too many resources.
First checks
Restart the computer, close unused apps and check whether updates are running in the background.
Storage and startup
Keep enough free storage and disable startup apps you do not need every day.
Browser and security
Close unused tabs, remove suspicious extensions and run a security scan if the slowdown appeared suddenly.
When to get help
If the computer freezes, overheats, shows repeated errors or storage is almost full, a deeper check may be needed.
Frequently asked questions
Will restarting really help?
Often yes. It clears temporary issues and finishes some update steps.
Should I install a cleaner app?
Be careful. Many cleaner apps are unnecessary. Start with built-in settings and trusted security tools.
Could malware make a computer slow?
Yes. Sudden slowdown, pop-ups or unknown apps are warning signs.
