Verified Google Review

Laptop diagnosis & repair

★★★★★

My laptop suddenly stopped working, and they picked it up within a few hours, exactly when they said they would. Later that same day they had already diagnosed the problem and contacted me with a clear explanation and a quote before carrying out any work.

A special thanks to Michael, who took the time to explain what had gone wrong. My laptop is now working perfectly again.

What A Slow Or Infected Computer Looks Like

Most people don’t know whether it’s a virus, too much software, or the machine getting old. You don’t need to know — that’s what the free diagnosis is for.

Slow to start upTakes several minutes to reach the desktop, then several more before it’s usable.

Laptop running slow generallyPrograms take forever to open, the cursor lags, everything feels like wading through treacle.

Freezing and crashingThe laptop freezes, programs stop responding, or it restarts itself without warning.

Pop-ups and advertsAdverts appearing on the desktop, in browsers, or over other windows. Often a sign of adware or malware.

Browser has been hijackedYour homepage or search engine changed on its own, or toolbars you never installed have appeared.

Fan constantly runningThe laptop is hot and loud even when you’re doing nothing. Usually something running in the background.

Blue screen errorsWindows crashes to a blue screen, with or without an error code, and reboots itself.

Computer won’t start properlyIt powers on but won’t boot into Windows, gets stuck on a logo, or loops through repair screens.

Full of software you never installedBloatware and trial programs that came with the laptop, all launching at startup and slowing it down.

MacBook running slowSpinning beachball, slow startup, storage full, or apps hanging on macOS.

Storage completely fullWarnings about disk space, nothing will save, and updates refuse to install.

Ransom or scam messagesA message claiming your files are locked, or a fake “Microsoft support” number on screen. Don’t call it — call us.

Our promise to you

Free Diagnosis.
Fixed Price. No Obligation.

“My laptop is slow” can mean ten different things, and you shouldn’t have to guess which one before agreeing to pay. So we come out, look at the machine properly, and work out what’s actually wrong.

Then we tell you which fixed-price package it needs and how long it will take. If you don’t want to go ahead, that’s completely fine — you pay nothing and we leave.

When work does go ahead, you pay once the computer is back in front of you and you’re happy with it.

The process

How It Works

Five steps, and you can stop at step three without paying anything.

1

Tell us what it’s doing

Message us on WhatsApp or call. Describe the symptoms in plain English — “it takes ten minutes to start up” or “there are adverts everywhere” is plenty. Tell us whether it’s a Windows laptop, a desktop PC or a MacBook, and give us your postcode.

2

We come to you

We agree a time that suits you, including evenings and weekends, and come to your home or workplace. You’ll get live journey updates through WhatsApp so you know exactly when to expect us.

3

Free diagnosis, then a fixed price

We check the machine properly and work out what’s actually wrong. Then we tell you which package it needs, what it costs and how long it’ll take. No charge for this, and no obligation to go ahead.

4

We fix it while you’re there

Almost all software work is done at your table, with you present. You can see what we’re doing the whole time. If a clean reinstall is needed and you’d rather not wait, we can collect the machine and return it instead.

5

You test it, then you pay

We’ll restart it with you, show you the difference, and walk you through what we changed. You pay once you’re happy it’s working.

Not just “running a scan”

What We Actually Do To Speed It Up

Plenty of places run one antivirus scan and hand it back. Here’s the real list.

Making it faster

  • Strip out manufacturer bloatware and trial software
  • Disable unnecessary startup programs and background services
  • Clear temporary files, caches and old update leftovers
  • Check disk health and free up storage space
  • Apply Windows and driver updates properly
  • Check for overheating and thermal throttling
  • Tell you honestly if an SSD upgrade is the real answer

Cleaning out infections

  • Full scan for malware, adware, spyware and trojans
  • Remove browser hijackers, toolbars and rogue extensions
  • Reset your homepage and default search back to normal
  • Clear out rogue scheduled tasks and startup entries
  • Stop fake “your computer is infected” pop-ups and scam warnings
  • Set up antivirus properly and leave it working
  • Explain what let it in, so it’s less likely to happen again

Being straight with you

Software Or Hardware?

Sometimes a slow laptop isn’t a software problem at all. We’ll tell you either way.

Covered by this service

Slow performance, freezing, crashing, pop-ups, viruses and malware, browser hijacks, bloatware, blue screens, startup failures, Windows corruption, full storage, and clean reinstalls.

All fixed at the prices above, with no parts to buy.

If it turns out to be hardware

A failing hard drive, dying battery, faulty RAM or a broken screen won’t be fixed by cleaning up software, and we won’t pretend otherwise.

If that’s what we find, we’ll tell you during the free diagnosis and quote it separately — you still pay nothing for the visit if you’d rather not go ahead. Often the honest answer is an SSD upgrade, which makes an old laptop feel new for less than replacing it.

Fixed Around Your Day, Not Ours

7am – 11pm, 7 days a week

Most repair shops close at five, which is exactly when you get home and remember the laptop still isn’t working. We take bookings in the evening and at weekends, so you don’t have to take a day off to get your computer fixed.

Common questions

Frequently Asked Questions

Will I lose my files? +
No. Speed-up work and virus removal don’t touch your documents, photos or emails. For a clean Windows reinstall, we back everything up first, reinstall, then put your files back and check them with you before we leave. We’ll always tell you before doing anything that affects your data.
Do you need my password? +
We’ll need you to log the computer in for us, but you don’t have to hand the password over — you’re welcome to type it yourself, and to stay with the machine the whole time. We never need your banking passwords, card details or email passwords, and we’ll never ask for them.
Does anyone else see my screen? +
On some jobs we bring in a specialist technician remotely, who may view the screen to help diagnose a fault. Our specialists work under contract to ALVA PC and may be based outside the UK. They only see what’s needed to diagnose the problem, and we won’t open your emails, documents, photos or saved passwords without asking you first. We’ll always tell you before we connect anyone, and you can say no — we’ll simply carry on without them.
How much does it cost? +
Speed-up and bloatware removal is £85, virus and malware removal is £110, no-boot repair is £110, and a clean Windows reinstall is £130. Every price includes the callout. See the full breakdown above.
Is the diagnosis really free? +
Yes. We come out, look at the machine, and tell you what’s wrong and what it costs. If you decide not to go ahead, you pay nothing at all — no callout charge, no diagnosis fee.
Do I need to know whether it’s a virus? +
Not at all. Most people can’t tell the difference between an infection, too much startup software, and a machine that’s simply out of disk space — and they look identical from the outside. Just describe what it’s doing and we’ll work out which it is.
How long does it take? +
Speed-up work is usually done within 90 minutes at your table. Virus removal and boot repairs are up to two hours. A clean Windows reinstall takes longer, so we’ll either work through it with you or collect the machine and bring it back — whichever suits you better.
Do you fix MacBooks as well as Windows laptops? +
Yes. Slow macOS performance, spinning beachballs, storage problems and apps hanging are all covered at the same prices. Windows desktops and all-in-one PCs are covered too.
What if the problem is hardware, not software? +
We’ll tell you during the free diagnosis. A failing drive, a dying battery or faulty memory won’t be fixed by cleaning up software, and we won’t charge you for a package that can’t solve your problem. We’ll quote the hardware work separately, and you’re free to say no.
Will it definitely be faster afterwards? +
On most machines the difference is obvious, particularly at startup. On a very old laptop still running a mechanical hard drive, software work helps but there’s a limit — in that case we’ll be honest and tell you an SSD upgrade is the change that actually transforms it.
What if the problem comes back? +
If the same problem returns within 14 days, we’ll come back out at no charge.
Can you come in the evening or at the weekend? +
Yes — we take bookings 7am to 11pm, seven days a week, and evenings and weekends are some of our busiest times.
Can you come to my workplace instead of my home? +
Yes, wherever that’s practical within our coverage area. Just let us know the address and any access details when you book.
When do I pay? +
After the work is finished and you’ve tested the computer yourself. Never before.
