Slow computer: what should you check before a repair?

Slow performance can come from storage, software, updates, heat or hardware. A few simple observations can make the assessment more useful.

Key point

Note when the slowdown appears, protect important files and avoid unknown cleanup tools. If the device becomes very hot, makes unusual noises or loses files, stop testing and request an assessment.

01 ·

Describe the symptom precisely

Note whether the computer is slow at startup, in one application, during video calls or all the time. Record when it began, any messages and recent changes. Slowness limited to the Internet may not come from the computer; compare another device on the same network.

02 ·

Run a few safe checks

Restart the device, close unused applications and check free space with the built-in Windows or macOS tools. Review pending updates without installing a random cleanup utility. Task Manager or Activity Monitor may reveal an application that constantly uses the processor, memory or disk.

03 ·

Know when to stop testing

New mechanical noises, shutdowns, odours, excessive heat, disappearing files or repeated security alerts are reasons to limit further testing. Never include a password in a request. If important data is not backed up, say so before any repair or reset.

Prepare a useful support request

Gather the device model, operating system, essential applications, exact message, tests already performed and your location. In Victoriaville, home or on-site help may be arranged by appointment; many software issues can also be reviewed remotely across Quebec.

A clear decision starts with the right context.
