Symptoms

What People Actually Call About

You do not need to know what is wrong to call. Describe what the machine is doing in ordinary words and we will work out the rest — that is the job. Here are the ones that come up week after week, and what normally sits behind them.

It Will Not Turn On

No lights, no fan noise, a black screen, or it starts and dies a second later. This is almost always one of a short list: the power supply or charger, the battery, a stick of memory that has worked loose, or the motherboard. We test them in order — cheapest and most likely first — and tell you which one it is before anything gets replaced. A machine that will not power on is also the classic case where nothing can be done remotely; there is no computer running for us to connect to.

It Is Unbearably Slow

Slow is a symptom, not a diagnosis, and the causes have wildly different price tags. It might be a mechanical hard drive that a modern operating system has simply outgrown, too little memory for the way you work, a dozen programs quietly launching at startup, a drive that is failing and retrying bad sectors, or malware using the processor for somebody else. We measure which one it is rather than guessing, because guessing here is how people end up replacing a whole computer to solve a problem that a single inexpensive part would have fixed.

A Blue Screen, Or It Restarts By Itself

Windows stops with a blue screen when something at the very bottom of the system misbehaves — usually a driver, failing memory, a dying drive, or heat. The screen carries a stop code and the machine writes a crash file; both of those name the culprit far more often than people expect. If it happens again, photograph the screen with your phone. It genuinely shortens the job.

Pop-Ups, Warnings And Scareware

A full-screen warning that says your computer is infected and gives you a number to call is itself the attack. Real security software never asks you to phone anyone, and neither Microsoft nor Apple puts a support line on a web page. We clear it out, then find how it got in — a browser extension, a bad download, a hijacked search setting — because removing the pop-up without closing the door means you will see it again.

You Clicked Something In An Email

Everybody does eventually. The invoice you were half expecting, the delivery notice, the message that looked exactly like your bank. What matters now is speed and honesty, not embarrassment. We treat it as a security incident rather than an inconvenience: what ran, what it touched, which accounts were signed in on that machine, and what needs a new password today. Skip ahead to what to do right now if it just happened.

A Cracked Screen Or A Broken Hinge

Laptop screens, hinges, keyboards and batteries are replaceable parts, and on most business-class machines they are straightforward. We identify the exact panel or part for your model, quote it to you before it is ordered, and fit it. On some very thin laptops the screen and the lid are one bonded assembly, which changes the sum completely — we tell you that up front, along with whether the repair still makes sense.

It Is Clicking, Or Files Have Vanished

A drive that clicks, grinds or freezes the whole computer for thirty seconds at a time is a drive telling you it is going. Stop using it. Every further minute a failing drive spends powered on is a minute it can spend making a recoverable situation worse. This is where repair ends and data recovery, backup and forensics begins, and it is a different discipline with different tools.

It Gets Hot, Then Shuts Itself Off

Usually dust. Fans and heatsinks fill with it, the machine can no longer move heat out, the processor slows itself down to survive, and eventually the computer cuts power to protect itself. So we open it up, clean the fans and heatsinks properly, and renew the thermal paste that has dried out. It is unglamorous and it is one of the biggest speed improvements an older machine will ever get. Cleaning machines on a schedule, before they start complaining, is exactly why preventative maintenance is written into a managed IT agreement.

The Printer Has Stopped

Printers fail in boring, fixable ways: a driver that a Windows update quietly replaced, a print queue jammed by one bad document that now blocks everything behind it, a printer that was given a new address by the router and never told the computers, or scanning that works while printing does not. Nearly all of this is fixable remotely while you stay in your chair.

The Wi-Fi Keeps Dropping

First we establish whether it is the computer, the router or the internet connection itself, because all three feel identical from the desk. On one machine it is often a wireless card whose power-saving setting switches it off, or an old driver. Across a whole house or office it is usually where the router sits, a neighboring network on the same channel, or asking one consumer router to cover more building than it can. That larger version is networks, servers and cloud work.

How We Reach You

Fixed Remotely In Minutes, Or Hands On The Machine

We are remote-first because it is faster for you, not because it is easier for us. Most software problems are solved in the time it would take to drive to you. But some problems cannot be solved down a wire, and pretending otherwise wastes an afternoon of your day.

Usually Sorted Remotely

  • Malware and pop-up removal on a machine that still starts
  • A computer that has become slow, and the startup clutter behind it
  • Windows or macOS updates that fail, hang or keep reappearing
  • Printers, drivers and jammed print queues
  • Email that has stopped sending or receiving, and Microsoft 365 sign-in
  • Installing, repairing or reconfiguring software
  • Settings that changed and nobody knows how
  • Being shown how to do something, on your own screen

A remote session starts only when you allow it, you watch everything that happens on your own screen, and you can end it at any moment. We tell you what we are about to do before we do it.

Needs Hands On The Machine

  • Anything that will not power on or will not reach the desktop
  • Screens, hinges, keyboards, batteries, power supplies and fans
  • Fitting a solid-state drive or extra memory
  • Cleaning out a machine that is overheating
  • A failed or failing drive, and getting the data off it
  • Cabling, wall points, switches and mounting access points
  • Setting up a new computer at the desk with its printer and screens
  • An office with no working internet — nothing can be remoted into

On-site visits are scheduled with you. Fresno, Clovis, Madera, Merced, Visalia, Tulare, Hanford, Modesto, Stockton, Sacramento and Bakersfield are all on-site territory — see the full Central Valley service areas.

Emergency

If You Think You Have Malware, Do This Right Now

A pop-up you cannot close, a link you wish you had not clicked, or somebody on the phone claiming to be from Microsoft. This is the part that matters in the first ten minutes, and none of it requires any technical skill.

  1. Disconnect From The Internet

    Unplug the network cable, or turn off the Wi-Fi from the machine. Most modern malware has to reach the internet to finish its job — to download the rest of itself, to send off what it has taken, or to receive the instruction to start encrypting your files. Cutting the connection is the single most effective thing an untrained person can do, and it costs nothing to be wrong about.

  2. Do Not Type Any Password On That Computer

    Not to “log in and check”, not to dismiss the warning, not into your bank. If something is recording keystrokes, everything you type goes with it. Change passwords from a different device — your phone on cellular data, or another computer entirely.

  3. Do Not Call The Number On The Screen

    And do not let anybody who telephoned you connect to the machine. Nobody legitimate calls to tell you your computer is infected, and no real error message has ever included a support phone number. If you have already let a caller in, say so plainly when you call us — that machine has to be treated as fully compromised, and knowing changes what we do first.

  4. Do Not Pay Anyone

    Not the pop-up, not the caller, not the ransom note. Paying funds the next one and very often returns nothing. Watch especially for the refund trick, where a caller shows you that they have “accidentally refunded too much” and asks you to send the difference back — that fake screen is how the money actually leaves real accounts.

  5. Leave It Alone And Call Us

    Resist running three cleanup tools you found through a search; several of the top results for that search are the problem, not the cure. Turning the computer off is fine and often sensible. Then call (559) 507-2076 or send us a message and tell us exactly what you saw and what you clicked.

Then Change These Passwords, From A Different Device

  • Your email first. It is the password-reset route into everything else you own, so it is the account an attacker wants most.
  • Online banking, and anything holding a saved card or bank detail.
  • Work accounts and remote access — and tell whoever looks after your company IT before you do anything else, even if the computer is yours.
  • Anything that shares that password. If the same password is used in two places, both are now compromised.
  • Turn on two-step verification wherever it is offered. A stolen password is worth far less when a code on your phone is also needed.
  • If banking or card details were used on that machine, tell your bank. They would far rather hear from you early.

This advice is free and it works whether or not you ever call us. If it turns out to have been nothing, you have lost an evening and gained better passwords.

Virus & Malware

What “The Virus Is Removed” Should Actually Mean

Running a scanner, deleting what it flags and rebooting is not removal. It is the part everybody can see. An infection is only genuinely gone when the way it starts, the way it hides and the way it came in have all been dealt with.

What We Check After The Scan

  • Everything set to run automatically — startup entries, scheduled tasks and services, which is where infections re-launch themselves from
  • Browser extensions, changed home pages and hijacked search settings, the most common thing left behind
  • Proxy and DNS settings, which can quietly send your traffic somewhere else while everything looks completely normal
  • New user accounts, and any remote-access software that a caller installed while they had you on the phone
  • Whether the antivirus, the firewall or Windows Update was switched off — disabling the defenses is usually step one for the malware, and nobody switches them back on afterwards
  • Where the machine tries to connect once it is back online, which is the honest test of whether anything is still resident
  • How it got in, so the same route is not left open behind us

Sometimes The Honest Answer Is To Rebuild It

We would rather say so than hand back a machine we are not sure about. A wipe and reinstall is the right call when a stranger on the phone was given remote control, when files have been encrypted, when the infection sits below the operating system, when the same thing comes back after a clean, or when the computer holds financial, medical or client records and “probably clean” is not a standard anyone should accept.

A rebuild is not a disaster and it is not us giving up. It means copying your data off and checking it first, reinstalling the operating system from scratch, putting your programs and printers back, returning your files, and then setting up a backup so that the next bad day is an inconvenience instead of a catastrophe. That backup piece is covered properly under data recovery and backup.

Upgrades

Upgrades Still Worth Doing — And When To Stop Spending

Two upgrades transform an older computer, and most of the others do not. Here is what each one actually fixes, and just as importantly what it will not, so nobody spends money on the wrong end of the problem.

Upgrade What It Genuinely Fixes What It Will Not Fix
Solid-state drive (SSD) Long start-ups, programs that take an age to open, and the general sense that the computer is always waiting. On any machine still using a spinning hard disk this is the single biggest improvement available, and it is usually not close. A machine short of memory, an infection, or a fault on the motherboard.
More memory (RAM) Freezing and stuttering once several programs or a lot of browser tabs are open, and the pause every time you switch between them. Slow start-up caused by an old hard drive. Adding memory to a machine with a spinning disk disappoints people constantly.
Clean-out and new thermal paste Overheating, roaring fans, shutdowns under load, and the slowdown a hot processor imposes on itself to survive. A part that has already physically failed.
Fresh operating system install Years of accumulated software mess, updates that will not complete, and inherited settings nobody remembers making. Any hardware fault. If the drive is dying, a reinstall makes it worse.
Larger drive with everything moved across Running out of space, and carrying a machine you like forward a few more useful years. A drive that is already failing — that is recovery first, upgrade afterwards.

When A Computer Is Not Worth Repairing

We will tell you. It is the least profitable sentence in this business and it is the reason people call back years later. The signals are consistent:

  • The repair approaches what a comparable replacement machine would cost, especially once a second part is involved
  • The memory and the drive are soldered to the board, so the two upgrades that would have helped are not possible
  • The parts are no longer manufactured, and what is available is salvaged with an unknown history
  • The operating system is out of support and this machine cannot be upgraded — that means no more security patches, which matters far more than speed
  • It is a laptop with more than one thing failing at once, which is usually age rather than bad luck

When that is the verdict we say so, help you work out what to buy for the way you actually use a computer rather than what is on the end-cap, and move everything across. We would rather sell you nothing today.

New Machines

New Computer Setup, And Moving Everything Across

The unpacking is the easy part. What people dread is the week afterwards, when something they needed turns out to have stayed behind on the old machine.

What “Everything” Includes

Documents, photographs, downloads and whatever is loose on the desktop are the obvious ones, and they are rarely the ones that cause trouble. The items people forget are the ones that hurt: browser bookmarks and saved logins, email — including older archived mail that lives only on that computer — the programs themselves along with their license keys, scanners and printers, and the small settings that make a computer feel like yours rather than like a rental.

We also deliberately leave things behind: the trialware the manufacturer pre-installed, the toolbars, the duplicate security products fighting each other, and anything we found while cleaning the old machine. A migration is the one clean opportunity to not carry a decade of clutter forward.

And we do not wipe the old computer on the same day. It stays exactly as it is until you have lived on the new one long enough to be sure nothing is missing. When you are ready, we erase it properly before it is donated, recycled or handed on — deleting files and emptying the recycle bin does not remove them from the drive, and a second-hand machine sold with its data still readable is a genuinely common way for personal information to escape.

Setting Up A New Machine For Work

A business computer needs more than the files. It has to be named sensibly, joined to the network so shared folders and printers appear, signed in to Microsoft 365 with mail and calendars working on the first morning, given the line-of-business software everybody else runs, and set up so the person who sits at it cannot accidentally break it. If that applies to several machines rather than one, the sane way to run it is proper network, server and cloud setup underneath it all.

Tech Support

Patient Help, Without Being Talked Down To

A large share of this work is not repair at all. It is sitting with somebody who wants to be shown how, and explaining it in a way that lets them do it themselves next time.

For Homes And Families

You do not need the right words. “The thing with the picture on it” is a perfectly good description and we will work out what you mean. We do not sigh, we do not take the mouse away and do it silently, and we do not answer in jargon either.

The usual requests: getting photographs off a phone and somewhere safe; setting up a printer that has never worked properly; email that stopped; video calls with family that keep failing; going through a suspicious message together before anyone clicks it; and making a computer easier to see, hear and read.

For Businesses And Their Staff

The same patience, applied where it saves money. When one person loses an hour a day to something nobody has ever shown them, that is a real cost, and it never appears on any invoice.

We are happy to work job by job. But if you are calling more than occasionally, a flat monthly managed IT agreement is almost always the better arrangement: monitoring, maintenance, helpdesk and on-site visits included, with around-the-clock telephone support as a client entitlement, so that problems get prevented rather than billed.

No subscription is required to get help. Call (559) 507-2076 with one problem and we will fix that one problem.

Questions

Repair Questions We Are Asked Most

More on the questions and answers page, or just ask us directly.

Do you work on Macs as well as Windows PCs?

Yes. Windows PCs, Macs, laptops, desktops, and the phones and tablets that sit alongside them. A household or an office is rarely all one thing, and the parts that go wrong are usually where they meet — mail, printing, file sharing, wireless.

Do I have to drop the computer off somewhere?

No, and there is nowhere to drop it. There is no walk-in shop — the address on this site is a mailing address only. We either connect remotely, which suits most software problems, or we come to you on-site in the Central Valley. Nobody sits in a queue holding a tower.

Will I lose my files?

Protecting what is on the machine comes before the repair. Where the drive still allows it, we copy the data off before doing anything that could put it at risk. If the drive itself is the fault, that becomes a data recovery job and we will be straight with you about what is realistic — nobody honest promises a failed drive in advance.

What will it cost?

We look first, then tell you what the machine needs and what it will cost, before any work starts. The first conversation is free, and if the answer is that the computer is not worth repairing, you will hear that instead of a quote.

Can you help if I am not in the Central Valley?

For anything that can be done remotely, yes — remote support covers the entire United States. On-site visits are for California's Central Valley, from Sacramento and Stockton in the north through Modesto, Merced, Madera, Fresno and Clovis, down through Hanford, Visalia and Tulare to Bakersfield.

The computer belongs to my employer. What should I do first?

Tell whoever looks after IT at your workplace straight away, before anything else — a work machine is usually connected to systems and accounts far beyond your desk, and the first minutes matter. Then follow the steps in what to do right now. Reporting it quickly is what gets people out of trouble, not into it.

Tell Us What The Computer Is Doing

Describe it in whatever words you have — it will not turn on, it is slow, a warning popped up. We will tell you whether it is a quick remote fix or something that needs hands on the machine. The first conversation is free.
