Garage & MOT Computer Power Supply Failure Repair
Computer Maintenance & Repairs offers fast, professional repairs for power supply failures in garage and MOT systems. If your computer won’t power on or shuts down unexpectedly, a failing PSU (power supply unit) could be the cause. We understand that downtime in garage environments can affect MOT bookings and diagnostic equipment – so we respond quickly to minimise disruption.

Common Symptoms of PSU Failure in Garage PCs
- No power or completely dead system
- Sudden shutdowns during use
- Burning smell or unusual noises from the system
- Inconsistent booting or crashing under load
- Flickering screens or unresponsive peripherals
Why Quick PSU Repairs Are Critical for Garages
Garage PCs running diagnostic software, vehicle testing systems (MOT), and print servers rely on stable power. If the PSU fails, systems may not log MOT tests, generate invoices, or perform emissions readings. Our engineers carry replacement PSUs compatible with industrial setups and can replace or upgrade on-site.
Our Power Supply Repair Services Include:
- Fault testing with multimeter and PSU tester
- Replacement of standard and industrial-grade PSUs
- Repair of faulty power connectors and cabling
- Surge damage inspection & component replacement
- 24-hour emergency service for mission-critical systems
