A desktop computer that won't start, keeps freezing, or has started behaving unpredictably brings office work to a standstill until the underlying issue is resolved. Computer Repair from Bestcare Facilities Management addresses the full range of desktop hardware and software faults affecting Nairobi offices.
Common Desktop Computer Faults
The most frequently reported issue is a computer that won't power on at all, which can stem from a failed power supply unit, a faulty motherboard, or in some cases a simple loose internal connection. Machines that power on but fail to boot into the operating system often point to a failing hard drive or corrupted system files, while random freezing or crashing during normal use is commonly tied to overheating, failing RAM, or software conflicts.
Computer Repair requests also frequently involve peripheral issues — non-functional USB ports, faulty display outputs, or unresponsive keyboards and mice — which are usually straightforward to resolve once correctly diagnosed.
Overheating: A Frequently Overlooked Cause
Dust accumulation inside a desktop tower restricts airflow around the processor and other heat-generating components, and over months or years this gradually pushes internal temperatures higher than the system is designed to handle safely. This shows up as random shutdowns, freezing during demanding tasks, or fans running loudly at full speed continuously. A thorough internal cleaning as part of a repair visit often resolves overheating-related instability that might otherwise be misdiagnosed as a failing component.
"Dust is one of the most underrated causes of desktop problems we see — a proper clean-out solves more issues than people expect." — Facilities Technician, Bestcare
Our Repair Process
Technicians begin with a structured diagnostic process, checking power delivery, testing memory and storage components, and inspecting for physical signs of damage or overheating before narrowing down the specific fault. Repairs range from component-level fixes like replacing a power supply or RAM module, to software-side resolutions like operating system repair or driver reinstallation, depending on what the diagnostic reveals.

Frequently Asked Questions
Why does my computer randomly shut down during use? This is often related to overheating from dust buildup or a failing power supply, both of which are checked during diagnosis.
Can a computer that won't boot always be fixed? In most cases yes, though the fix depends heavily on whether the cause is hardware or software related.
How long does a typical computer repair take? Straightforward repairs are often completed same-day, while component sourcing for less common parts may extend turnaround slightly.
Do you repair computers on-site or do they need to be taken elsewhere? Many repairs, including diagnostics and cleaning, can be handled on-site; more involved component repairs may require the unit to be taken for specialized work.
Will a repair affect the files already stored on my computer? Standard hardware repairs don't typically affect stored files, though backing up important data beforehand is always recommended as a precaution.
