Power supply replacement in St Albans: signs you need it
A dying power supply can mimic all sorts of other faults. Here are the symptoms we diagnose, the likely cause and how we fix it.
| Symptom | Likely Cause | Our Fix |
|---|---|---|
| Computer will not power on at all | Dead power supply unit | Test and replace the PSU |
| Random shutdowns under load | PSU cannot deliver enough power | Fit a higher wattage quality unit |
| Burning smell or buzzing | Failing capacitors inside the PSU | Immediate replacement for safety |
| Reboots when gaming | Voltage drop under heavy demand | Upgrade to a stable rated supply |
| Fans spin then stop | Protection circuit tripping | Diagnose and replace faulty unit |
Try this before you call
- Check the wall socket and cable with another device first
- Make sure the switch on the back of the PSU (power supply unit) is set to on
- Listen for a buzzing or clicking sound from the unit
- Look for a small red voltage switch set to the wrong region
- Note any burning smell and stop using the machine if present
If your machine still shows no signs of life, the power supply is a likely culprit and should be tested by a professional. Microsoft offers startup troubleshooting at support.microsoft.com/windows, and we handle the hardware safely for you.

Power supply replacement: your questions answered
How do I know if my power supply has failed?
Common signs are a computer that will not turn on, random shutdowns under load or a burning smell. We can confirm it quickly with a proper test during our call-out.
Can a bad power supply damage other parts?
Yes. A failing unit can deliver unstable voltage that harms your motherboard (the main circuit board), graphics card and drives, which is why a quality replacement is so important.
Will I lose my data during a power supply swap?
No. Replacing the power supply does not touch your storage drives, so your files and settings stay exactly as they were.
Do you come to me?
Yes. Many problems are fixed on the spot; some repairs need the workshop.
Why power supply replacement matters
It protects everything else
A cheap or failing unit can send bad voltage to your motherboard, graphics card and drives. A quality replacement protects the parts you have already paid for.
The right wattage counts
Too little power causes crashes, too much wastes money. We size the unit to your actual components so it runs cool, quiet and reliable.
Safety is not optional
Power supplies handle mains voltage and can be dangerous when they fail. We test and replace them safely so you never take a risk with a faulty unit.
