Clean up software and upgrade RAM or SSD

Combine essential software maintenance with targeted hardware upgrades for the biggest performance gain on an aging computer. Software cleanup alone often produces a noticeable improvement, while adding RAM or swapping to an SSD can make an old machine feel new.

Steps

1. Uninstall unused programs through Settings (Windows) or Applications (Mac) to free disk space and reduce background processes.
2. Disable unnecessary startup programs using Task Manager (Windows) or System Settings > Login Items (Mac). Fewer startup items means faster boot times.
3. Run disk cleanup with the built-in OS tool to remove temporary files, cached data, and emptied trash.
4. Run a full malware scan with reputable antivirus software. Hidden malware is a common cause of unexplained slowdowns.
5. Update your OS and drivers to get performance patches and hardware compatibility fixes.
6. Add RAM if your machine has less than 8 GB and supports upgrades. Going to 8 or 16 GB dramatically improves multitasking. Check your model's specifications for compatible modules.
7. Replace an HDD with an SSD for the single most impactful hardware upgrade. Use cloning software to migrate your existing OS and data to the new drive.

Tips

• Do software cleanup first -- it costs nothing and may be all you need
• An SSD upgrade typically cuts boot time from over a minute to under 15 seconds
• Check manufacturer specs or a tool like Crucial System Scanner to verify RAM and SSD compatibility before purchasing
