No power at all
Nothing happens when you press the power button, or it switches off immediately. The power supply, connections and other components need to be considered.

Find your starting point
What does your PC do when you switch it on?
No power, no picture and Windows failing to load are different symptoms. A few observations help the engineer plan the right checks.
Fans run, but no picture
The tower appears to start but the monitor stays blank. Mention any diagnostic lights, beeps and whether the display works with another device.
Blank screen problemsCrashes, freezes or restarts
Tell us whether it happens at startup, during games or at random. Hardware, temperatures, drivers and software can produce similar symptoms.
Crashing and freezing PCsHot or noisy computer
Loud fans, heat buildup or shutdowns under load. Cleaning, airflow, fan condition and cooling hardware may all be part of the assessment.
PC cooling and fan serviceSlow performance
Long waits, stuttering and slow applications need checks before parts are purchased. Storage health, memory use and software can all affect performance.
Slow PC and upgrade optionsWindows will not load
The PC powers on but stops at an error, recovery screen or startup loop. Tell us about recent updates, new components and files that must be kept.
Startup and boot problemsFor connected equipment or other issues, see printer, keyboard and mouse problems, Wi-Fi and internet faults, unwanted pop-ups and malware, or other desktop problems.
Different PCs, different checks
From the family desktop to a custom gaming build
Tell us the make and model, or the main components if you built the PC yourself. You do not need a complete parts list to make an enquiry.
Branded home and office desktops
For Dell, HP, Lenovo and other prebuilt PCs, the model helps identify parts and access requirements. Small cases and proprietary power supplies may limit upgrade choices.
Custom and gaming PCs
Mention the processor, graphics card and power supply if known. Say whether the problem started after a build, upgrade or settings change, and whether it occurs only during games or demanding work.
All-in-one and compact PCs
A built-in screen or tightly packed case can change the work involved. Include the exact model rather than assuming standard tower parts will fit. For an iMac, see Mac repair options.
Know what to expect
Repair, upgrade or replace?
Start by finding the fault. An SSD or extra memory may help one computer, but will not resolve every slowdown, crash or startup problem.
- Assessment: confirm any callout or diagnostic fee before booking. An enquiry is free, but testing and repair work may be chargeable.
- Replacement parts: the quote should account for compatibility, labour and testing. Ask what warranty applies to the proposed work.
- A worthwhile upgrade: compare the cost with the PC’s age, condition and intended use. Graphics, memory and storage changes may also depend on the case, motherboard and power supply.
Before you enquire
Useful details for a desktop enquiry
- The make and model, or a brief component list for a custom build. Add photos of labels or the fault if useful.
- What lights, sounds or messages appear, and whether the screen displays anything.
- Any recent upgrade, move, power interruption or settings change, plus when the problem occurs.
- Your postcode, important files and whether you have a backup. For a visit, mention access and space around the computer.
Do not include passwords or recovery keys in the enquiry form.
A clear next step
A clear diagnosis before buying parts
A good repair plan connects the symptoms to the testing, proposed work and cost.
Describe the behaviour
Tell us what happens from pressing the power button to the point it fails. Include the computer details and your postcode.
Discuss testing and access
Suitable local help is checked. Confirm whether a visit or workshop assessment makes sense and agree any assessment charges.
Approve the repair plan
Review the cause, compatible parts and quote. Agree the work and ask which checks will confirm the PC is ready to use again.
Enquire about a repair
Free enquiry. No obligation to book.
Choose a suitable arrangement
Choose the right setting for the fault
A desktop is often part of a larger setup. The monitor, network and connected equipment can matter as much as the tower.
Home and office visits
Useful for faults involving the monitor, printer, Wi-Fi or equipment at your desk. Hardware work depends on suitable access, tools and parts being available.
Workshop testing
Intermittent faults, parts substitution and specialist repairs may need more time and equipment. Confirm which items to provide and how the PC will be transported.
Remote support
Some software, configuration and unwanted pop-up problems may be suitable if Windows starts and the internet works. Physical hardware faults need a different approach.
If files matter most, say so before a reset, reinstall or storage replacement is discussed. If the PC smells burnt, has visible damage or may have a liquid leak, stop using it and explain this before assessment. Do not open the power supply.

Local help, checked first
PC repair near you, checked by postcode
Enquire about desktop support in London or elsewhere in the UK. We will check suitable help for your address and the work needed.
Tell us if the PC is difficult to move or is part of a business setup. A coverage page does not confirm an appointment; local availability and the service arrangement are discussed before booking.

PC repair questions
Practical details to help you arrange the right assessment.
Can you help with a PC I built myself?
Yes, you can enquire about custom and gaming PCs. Include the main components if you know them, any recent changes and exactly what happens. Suitability and the testing needed are checked before a booking is arranged.
Do I need to provide the monitor and cables?
Ask before a workshop handover. The tower alone may be enough for some faults, but display or connection problems may require the relevant monitor, cable or accessory. For a visit, leave the affected setup available to show the engineer.
Can a PC that will not turn on be fixed remotely?
No. Remote support needs a computer that starts and can connect to the internet. A no-power fault requires physical checks, and the cause cannot be confirmed from the symptom alone.
Can you fit parts I have already bought?
Mention the parts when you enquire and ask whether installation can be arranged. Compatibility and condition need checking first. Agree labour charges and how warranty responsibilities apply to customer-supplied components.
Will a repair keep my files intact?
That depends on the fault and the work required. Back up accessible files if it is safe, and identify important data before authorising work. File recovery is a separate consideration and cannot be guaranteed.
How soon can my PC be repaired?
Availability, diagnosis, replacement parts and testing affect the timing. Mention any work or gaming deadline, then confirm an estimate with the engineer. An enquiry does not guarantee a same-day visit or repair.
