There is no shame in fixing things yourself. There is also no shame in knowing when you shouldn’t. The people who cause themselves the most trouble are the ones who can’t tell the difference — who push past their limit because asking for help feels like admitting defeat, and end up turning a fixable problem into a significantly worse one.

A good mechanic will tell you exactly which things on your car you can handle yourself and which ones require a lift, a specialized tool, or ten years of experience to do safely. This is that conversation, for your computer.

Things most people can handle themselves

• Restarting the computer or router. The most underrated fix in computing. Try it first, always.
• Running Windows Update. Settings → Windows Update → Check for updates. Let it run.
• Clearing the browser cache. Usually found under browser settings, History, or Privacy. Fixes many strange browser behaviors.
• Checking the print queue and clearing stuck jobs. A stuck job in the queue blocks everything behind it. Cancel it and try again.
• Checking that a cable is firmly plugged in. Ethernet cables, printer cables, power cables — they work themselves loose. Check before assuming something is broken.
• Changing a printer cartridge. If the printer is telling you the ink is low and the print quality is suffering, this is within reach for most people.
• Exporting bookmarks before getting a new computer. Every browser has this option. Use it.
• Updating a password that you know but the app isn’t accepting. If you recently changed a password elsewhere, update it in the app that’s asking for it.
• Uninstalling a program you knowingly installed. Settings → Apps → find it → Uninstall. Straightforward for anything you put there yourself.

Things worth a phone call first

• Anything involving the Windows Registry. Instructions online will tell you to edit the registry to fix all manner of things. The registry is the nervous system of Windows. One wrong change and the computer may not start. Don’t touch it without guidance.
• Removing malware that’s already installed. Malware actively resists removal. Some types reinstall themselves, hide in places ordinary tools don’t reach, or are designed to look like they’ve been removed when they haven’t. A partial removal can be worse than none.
• Recovering files from a failing hard drive. If a drive is making clicking or grinding sounds, stop using it immediately. Every write to a failing drive risks overwriting data that might otherwise be recoverable. This is a call-first situation.
• Setting up a new email account from scratch on an older system. The settings involved — server names, port numbers, security protocols — are specific to each provider and vary enough that a wrong entry produces errors that are difficult to interpret without experience.
• Anything where you’ve already tried something and made it worse. Stop. Don’t try another thing. Call. The more that’s been changed without documentation, the harder the recovery becomes.

Things to just hand off

• Physical repairs. Replacing a laptop screen, a keyboard, a charging port, a cooling fan. These require disassembly, specific parts, and the knowledge that what you’re opening is more fragile than it looks.
• Data recovery from a dead drive. If the drive isn’t being recognized at all, software tools won’t help. Professional data recovery exists and works — but it requires specialized equipment and a clean environment.
• Setting up a new computer from scratch for someone else. Doing it for yourself, you can ask questions along the way and make judgment calls. Doing it for a parent or grandparent, you’re making decisions that will affect them for years. A professional setup done right is worth considerably more than a well-meaning but incomplete one.
• Anything that involves your financial accounts behaving strangely. If you suspect something has accessed your banking, investment, or payment accounts through your computer — stop using the computer and call both your bank and a technician.
• Anything a pop-up told you to do. If instructions to fix something arrived in a pop-up window, a phone call you didn’t initiate, or an email you weren’t expecting — do not follow them. Call someone you trust instead.

A note on internet instructions

The internet contains an enormous amount of computer repair advice — some of it excellent, much of it outdated, some of it actively dangerous. Instructions written for Windows 7 may cause problems on Windows 11. A fix that worked for one person’s specific configuration may not apply to yours. And some of what appears in search results is deliberately designed to lead you toward downloading something harmful under the guise of fixing something.

Use online instructions carefully. Prefer official sources — Microsoft’s own support pages, your hardware manufacturer’s website — over random forums. And when something says “download this tool to fix the problem,” be skeptical until you know exactly what you’re downloading and where it came from.
