Troubleshoot a computer problem before booking repair

How to use these computer troubleshooting guides safely

Start with the symptom you can observe rather than guessing which part is broken. A computer that feels slow can have a Windows problem, a nearly full drive, failing storage, too little memory, overheating or background software using resources. A laptop that will not charge can involve the adapter, battery, USB-C power negotiation, charging port or the board. The safest first step is to identify what changed, when the problem began and whether the computer still starts normally.

If important files are involved, protect the data before trying resets, formatting or repeated repair attempts. A drive that clicks, disconnects, disappears from BIOS, asks to be formatted or becomes extremely slow should be treated differently from a normal Windows software problem. Avoid copying large amounts of new data to a drive that may be failing. For recovery-sensitive cases, see our data recovery service in Montréal before making destructive changes.

When a repair shop visit is more useful than another software fix

Some problems need tools, spare parts or longer testing. Internal cleaning, SSD or RAM installation, charging-port diagnosis, stress testing, repeated blue screens, random black screens and storage-health checks are usually easier to diagnose on a workbench. Laptop Clinic accepts in-person drop-off by appointment at 6630 Sherbrooke St W, Montréal, QC H4B 1N7. Customers who prefer not to travel can also use pickup and delivery, while problems tied to your home Wi-Fi, printer or network may be better suited to on-site computer support.

These guides are written to help you make a better decision, not to push unnecessary repairs. If a simple setting or cable check solves the problem, no repair is needed. If the symptoms point to hardware, unstable storage or repeated Windows failure, a proper diagnosis can prevent buying the wrong part or losing time on repeated reinstalls.

Need a diagnosis instead?

If your problem does not match a guide exactly, send the symptoms by WhatsApp, Messenger or text message. Diagnosis is usually better than buying parts at random.
