Simple ways to speed up a slow computer
By Everyday Guide Hub Editorial Team · Last updated October 28, 2026
Before replacing an older laptop or desktop, try these straightforward checks that often improve performance.
Restart and update
It sounds simple, but a full restart clears temporary processes and applies pending updates. Install operating system and app updates, as they often include performance and security fixes.
Check what starts automatically
Many apps launch when the computer starts and keep running in the background. Open your system's startup settings and disable programs you do not need immediately.
Look at resource usage
Task Manager on Windows or Activity Monitor on macOS shows which apps use the most memory and processor time. Close or uninstall heavy apps you rarely use.

Free up storage space
A nearly full drive can slow a computer down. Remove unused programs, empty the downloads folder, and move large photos or videos to external or cloud storage. Built-in storage tools can show what takes the most space.
Tidy your browser
Dozens of open tabs and extensions use memory. Close tabs you do not need, remove unused extensions, and clear old cached data occasionally.
Scan for malware
Run a scan with reputable security software. Unwanted programs can consume resources.
Consider simple upgrades
For some older computers, adding memory or replacing a traditional hard drive with a solid-state drive can make a noticeable difference. Check compatibility or ask a qualified technician first.
Always back up important files before making major changes.
Key takeaways
- Restart regularly and keep software updated.
- Disable unnecessary startup programs.
- Free up storage and reduce browser tabs and extensions.
- Back up files before upgrades or major changes.
Frequently asked questions
Will more memory always speed up my computer?
It helps if memory is the bottleneck, but not in every case. Check resource usage first.
Do I need to reinstall the operating system?
Usually not as a first step. Try simpler fixes before a full reinstall, and back up first.
