1. Slow Performance

Symptoms: Programs take ages to load, files lag, or your device feels sluggish.
Causes: Too many background apps, fragmented hard drives, or outdated hardware.

Step-by-Step Fix:

Clear temporary files: Use Disk Cleanup (Windows) or Optimized Storage (Mac).
Uninstall unused programs: Free up space and reduce background processes.

2. Overheating

Symptoms: Fans run loudly, the device feels hot, or it shuts down unexpectedly.
Causes: Dust-clogged vents, faulty fans, or heavy multitasking.

Step-by-Step Fix:

Clean vents: Use compressed air to remove dust from your laptop or desktop.
Use a cooling pad: Improves airflow for laptops during intensive tasks.

Persistent overheating often signals deeper issues like failing fans or dried thermal paste. Our laptop repair Ottawa technicians can replace hardware and prevent long-term damage.

3. Virus or Malware Infections

Symptoms: Pop-up ads, sluggish performance, or unauthorized software installations.
Causes: Downloaded malicious files, phishing links, or outdated antivirus software.

Step-by-Step Fix:

Run a full system scan: Use trusted antivirus software like Malwarebytes or Norton.
Boot into Safe Mode: Restart your device in Safe Mode (Windows: press F8 during startup; Mac: hold Shift) to isolate and remove threats.

Stubborn malware can hide in system files or replicate itself. Our virus removal Ottawa experts use advanced tools to eliminate infections without risking your data.

4. Blue Screen of Death (BSOD)

Symptoms: A blue error screen forces your computer to restart.
Causes: Driver conflicts, hardware failures, or corrupted system files.

Step-by-Step Fix:

Note the error code: Write down the BSOD code (e.g., “CRITICAL_PROCESS_DIED”) and Google it for specific solutions.
Update drivers: Use Device Manager (Windows) or Software Update (Mac) to install the latest drivers.

Frequent BSODs often indicate failing hardware like a bad RAM stick or motherboard. Bring your device to GCOM Support for a thorough diagnosis.

5. Wi-Fi Connectivity Issues

Symptoms: Unstable internet, slow speeds, or “No Internet Access” errors.
Causes: Router glitches, outdated network drivers, or interference.

Step-by-Step Fix:

Restart your router/modem: Unplug it for 30 seconds, then reconnect.
Update network drivers: Go to your device manufacturer’s website for the latest drivers.

If issues persist, your network card might be faulty. Our Ottawa computer repair team can replace hardware or optimize your Wi-Fi setup.

6. Frozen Screen

Symptoms: The cursor won’t move, apps won’t close, or the system is unresponsive.

Regular freezes may indicate deeper issues like failing RAM or a corrupted OS. Let our technicians troubleshoot the root cause.
