What is on this site
This site covers everything you need to use, fix, or understand computers—from troubleshooting a frozen screen to setting up a Linux server.
It’s divided into four main areas: how-to guides for everyday problems, reviews of hardware and software, news on tech trends, and deep dives into operating systems and productivity tools.
Each section is organised by practical need. Need to recover a lost file? Start with the *Troubleshooting* guides. Want to compare two SSDs for a build? Check the *Reviews*. Curious how Windows 11’s new features actually work? Look under *Operating Systems*.
The site avoids jargon and focuses on clear steps, real-world examples, and the tools most people already have.
| Where | What is there | Go here if |
|---|---|---|
| Guides | Step-by-step fixes for crashes, slowdowns, and lost data | your computer is acting up |
| Reviews | Honest comparisons of hardware (GPUs, monitors) and software (Office suites, antivirus) | you’re choosing between two products |
| News | Breaking updates on OS patches, security threats, and new tech | you need to know what changed |
| Tutorials | Walkthroughs for Linux commands, PowerPoint shortcuts, and Outlook automation | you’re learning a new tool |
How to read a page here
Every guide starts with a problem statement—the exact issue you’re facing—and ends with a summary of tools used, so you know what’s required. Numbers in the text (like *Step 3*) mark the order of actions, while bold terms link to definitions or related guides.
Timings are given in minutes or seconds, not vague phrases like ‘a few moments.’
The first paragraph explains what the guide covers and what it *doesn’t*—so you can skip if it’s not relevant. Sidebars (marked with a ⚠️ or 💡) warn about common pitfalls or suggest alternatives.
If a step fails, the ‘What went wrong’ section at the end lists the most likely causes, in order of probability.
Ignore the ‘Also try’ section on a first read—it’s for when you’ve fixed the main issue and want to optimise further. The comments (if any) are for debates, not troubleshooting: use the contact page for questions.
When it does not work
Most issues on this site are resolved by checking three things first: the device’s manual (yes, even digital manuals), the error code (search for it with the exact wording), and whether the problem happens in Safe Mode or a live Linux USB.
If none of those help, the guide likely assumes a setup you don’t have—like a specific Windows version or hardware.
Before you give up
- Restart the device—half of all tech problems vanish after a cold boot.
- Check for pending updates (Windows, drivers, firmware) that might fix the issue.
- Test the problem on another account or a different device to rule out profile corruption.
- Search the exact error message (not a summary) on Google with ‘site:dataandquery.click’ to find related guides.
Who we are
This site is built by someone who still remembers debugging a 56K modem connection by ear.
| The colophon | |
|---|---|
| Written by | Sonia Nakamura, who runs the site and writes most of the guides, with a focus on clarity over technical depth. |
| Tested in | A 2019 Lenovo ThinkPad (Windows 11 Pro) and a Raspberry Pi 4 (Raspberry Pi OS) in a cluttered home office with three monitors. |
| Written with | VS Code for code snippets, OBS Studio for screen recordings, and a mechanical keyboard that’s outlived two laptops. |
| Learned from | A high school friend who rebuilt PCs for fun, and the Linux forums where people explain problems in three sentences. |
| Still getting wrong | Assuming ‘restarting’ means the same thing to everyone—some guides now include a ‘What does restarting mean?’ sidebar. |
The best tech advice isn’t about the latest gadget or the shiniest software. It’s about the quiet moments—when a command fails silently, when a driver update breaks more than it fixes, or when you realise the ‘easy’ solution is the one you missed. This site exists for those moments.
If you need something that is not here
If the guide you need isn’t published yet, it’s either too niche (like fixing a 1998 printer driver) or too broad (like ‘how to choose a computer’). The site focuses on specific problems with clear solutions, not opinions or overviews.
If you’re stuck, check the ‘Related Guides’ section at the bottom of any page—or use the contact page to suggest a topic. We’ll publish it if enough people ask.
The guides are grouped by category: App, Coding, Hardware, Operating System, Outlook and PowerPoint.
