Hardware Troubleshooting & Diagnostics Fault diagnosis, component replacement, upgrades and preventive maintenance
When a computer will not boot, beeps, shuts down under load or loses files, the cause is physical. Guessing which component failed is how people end up buying parts they did not need. We test systematically, tell you which part has failed, and lay out your options.
This is one of our IT support services in Kenya — managed support, repairs and troubleshooting for homes and offices.
Find the faulty part before buying a replacement
Hardware faults present as symptoms, not answers: a machine that powers on but shows nothing, beeping at startup, drives that click, memory errors under load, shutdowns that only happen on a hot afternoon. Each symptom narrows the field, but only testing confirms the cause.
We work through a machine in a fixed order — power, memory, storage, thermal, then peripherals — swapping known-good parts to isolate the failure. You get a clear answer: this component has failed, these are your options, this is what it involves. No parts replaced on suspicion.
Talk to a technician first
Describe the symptoms and we will say whether this is a workshop job, a remote fix or something you can safely ignore.
Get helpWhat we diagnose and repair
These are the hardware faults that account for most dead and unstable computers we see.
No power, no display, no POST
Power supply, mainboard, memory or graphics faults. We test the power chain and the components behind it in order, instead of starting with the most expensive possibility.
Beep codes and startup errors
Startup beeps exist to tell you something specific. We decode them and confirm the fault, which usually saves both time and unnecessary parts.
Failing drives and lost files
Clicking, slow reads and SMART warnings mean a mechanical drive is on its way out. We check drive health, copy data off where possible, and move you onto solid state storage before it fails completely.
Memory and stability faults
Crashes under load, applications that close themselves, blue screens that move around. Memory testing finds faults that ordinary troubleshooting never confirms.
Overheating and power faults
Fans that have stopped, blocked vents, failing power supplies and unstable power. Heat is the most common cause of premature hardware death in Kenyan offices.
Printers, scanners and peripherals
Devices that are not detected, print jobs that vanish, peripherals that drop off the network. We test the device, the cable, the driver and the connection until the weak link is found.
How hardware diagnosis works
Diagnosis comes before parts. That order is what keeps repair bills honest.
Symptoms recorded
What happens, when it started, and whether anything changed beforehand — a power cut, a move, a spill, new hardware. Context narrows the fault before we open anything.
Isolation testing
We test power, memory, storage and thermal behaviour in sequence, swapping known-good components to prove which one is failing rather than inferring it.
Repair, replace or upgrade
You get the finding and the realistic options: replace the failed part, upgrade while we are in there, or accept that the machine has reached the end of its useful life.
Test, document and return
The machine is stress-tested after the repair, and you receive a short record of what was replaced — useful for asset records and for spotting patterns across a fleet.
Who this is for
- Offices with several computers, where one failing machine slows a whole team down.
- Businesses without a support contract that need an honest answer on a single broken machine.
- Schools, churches and NGOs running mixed or donated hardware that needs to last.
- Anyone who has been told they need a new computer and wants a second opinion before spending.
