Desktop Computer Repair in Surrey, BC
Smart Geeks diagnoses and repairs desktop computers in Surrey, BC, including prebuilt towers and custom builds -- power issues, random shutdowns, no-display faults, and component failures.
Overview
Desktop towers are easier to open up than laptops, but that also means there are more individual components that can be the actual source of a problem: power supply, motherboard, RAM, storage, or graphics card.
We test components individually rather than replacing parts on a guess, which matters most on custom builds where compatibility and existing configuration need to be respected.
Smart Geeks is an independent repair shop and is not affiliated with, authorized by, or endorsed by any device manufacturer. Brand and model names are used only to identify the devices we can work on.
Common symptoms
- Desktop won't power on at all
- Random shutdowns or restarts during use
- Blue screen errors or repeated crashes
- No display output even though the PC seems to power on
- Unusual noises -- clicking, grinding, or a loud fan
- Overheating or thermal shutdowns
- Slow performance that's gotten noticeably worse
- Won't boot into the operating system
- USB ports or other connections that have stopped working
Our diagnostic approach
We test the power supply under load first, since a failing PSU can look like a dozen different problems. From there we check POST behaviour and any beep or error codes the motherboard reports.
Individual components -- RAM, storage, graphics card -- are tested in isolation where possible, along with a thermal inspection, so we can tell you specifically which part is at fault rather than replacing things speculatively.
Factors that may affect service
- Whether replacement parts are compatible with your existing build
- The age of the system and availability of matching components
- Whether the desktop is a custom build or a manufacturer prebuilt, which affects part sourcing
- How much dust or thermal buildup has accumulated, which can mimic other faults
Repair process
- 1
Intake
We record the symptoms and ask about any recent hardware or software changes.
- 2
Bench diagnostics
Power supply, POST behaviour, and individual components are tested.
- 3
Component isolation
We narrow the fault down to a specific part wherever the symptoms allow it.
- 4
Repair or replacement
This may include PSU or RAM replacement, storage swap, GPU reseating, or a thermal service (paste and fan cleaning).
- 5
Stability test and handback
We run the system under normal load before returning it to confirm the fix holds.
What to bring
- The full tower and its power cable
- Note any recent hardware changes, software updates, or power events (like an outage) before the issue started
- If it's a custom build, any details you have on the components used are helpful
Frequently asked questions
Do you work on custom-built PCs?
Yes. We test components individually and take your existing configuration into account rather than assuming a one-size-fits-all fix.
My PC turns on but there's no display -- what's usually the cause?
That can point to a graphics card, RAM seating, motherboard, or display cable issue. It's exactly the kind of symptom our bench diagnostic is built to narrow down before any parts are replaced.
Can you clean dust out of my computer?
Yes, thermal servicing (cleaning and, where needed, reapplying thermal paste) is part of what we offer when overheating or fan noise is the concern.
