7 checks before giving up on a slow PC

1. Check resource usage

Task Manager can show whether CPU, memory, disk or one specific application is consistently saturated. That is more useful than installing random “cleaner” software.

2. Check free storage

A nearly full drive can affect updates and overall performance. Remove temporary files, review downloads and move old copies to safe external storage.

3. HDD versus SSD

On older systems, replacing a mechanical hard drive with an SSD can make a major difference. Compatibility and backup planning should be checked first.

4. Startup applications

Many programs launch with Windows even when they are not needed. Reducing them can improve startup time, but unknown system services should not be disabled blindly.

5. Updates and security

Keep the operating system and applications current, while noting whether a problem started immediately after an update. Malware and overheating are also worth checking.

6. Back up before major changes

If the computer contains important data, protect it before reinstalling the system or replacing storage.
