Power, cooling, motherboards & components · No Fix, No Fee · Same-day call-out
When a computer won’t power on, shuts down at random, restarts on its own or overheats, the cause is usually a failing component. PC Masters provides hardware diagnostics and component-level repair for laptops and desktop PCs, at your home or business.
Your technician tests each part in turn, including the power supply unit (PSU), memory (RAM), hard drive or SSD, cooling fans, graphics card and motherboard, to find exactly what has failed. Common hardware repairs include PSU replacement, RAM testing and replacement, failed drive replacement, CPU cooler and thermal paste replacement, laptop DC jack and charging port repairs, and fixing faulty USB, audio and display ports.
You only pay to replace what’s actually broken, and we tell you the price before any part is ordered. Every replacement part is tested before we hand the computer back, and if an upgrade such as a faster SSD or extra memory would give an older computer a new lease of life, we’ll recommend it.

A technician visits your home or business, finds the cause and tells you what it will cost before any work starts.
Many parts are replaced there and then. If a part needs ordering or bench testing, we’ll take the device to our workshop and return it once it’s repaired and tested.
If we can’t fix it, you don’t pay for the repair. Every replaced part is tested before we hand the computer back. Every repair comes with a warranty from 1 month up to 36 months: our basic service includes 1 month, and the bigger the job, the longer the warranty.
Replacement parts are charged at the lowest manufacturer rate and agreed with you first. If a repair would cost more than the computer is worth, we’ll tell you honestly.
We test each component in turn, including the power supply, memory, drive, fans and motherboard, so we replace only the part that has actually failed.
Often, yes. A new SSD, memory or power supply can give an older computer years more use. If it isn’t worth it, we’ll say so before you spend anything.
It’s usually overheating or a power supply that can’t keep up. We clean the cooling, replace the thermal paste and test the power supply under load.
Yes, we fit new parts as standard. If a quality refurbished part would save you money, we’ll offer it as an option and explain the warranty.
