Introduction: Why DIY Hardware Support Matters
For many small businesses and home users, IT support isn’t always on speed dial. Whether it’s a frozen screen, an unresponsive printer, or your Wi-Fi acting up, tech issues can bring your workday to a halt. The good news? You don’t always need an expert to fix it.
Understanding a few basic troubleshooting techniques can save time, money, and a lot of frustration. This guide walks you through common hardware issues and how to fix them yourself, using simple explanations and practical steps—no tech jargon needed.
1. My Computer Won’t Turn On
What might be happening:
- Power cable is loose or unplugged.
- Power supply or battery may have failed.
- External devices (USBs, external drives) could be interfering with startup.
Try this:
✅ Double-check that the power cable is securely plugged into both the wall socket and the device.
✅ If using a laptop, remove the battery (if possible) and plug in the charger directly.
✅ Unplug any USB devices or accessories and try powering on again.
✅ Check for signs of power (fans spinning, lights blinking) and listen for beeps—these can hint at deeper hardware problems.
Still not working?
The issue could be a faulty power supply or motherboard, which may require professional help.
2. The Screen Is Blank or Flickering
What might be happening:
- Loose or damaged monitor cable.
- Display settings set to a different screen.
- Faulty graphics card or driver issue.
Try this:
✅ Check all video cables (HDMI, VGA, DisplayPort) and ensure they are plugged in tightly.
✅ Try a different monitor or TV to see if the problem lies with the screen or the computer.
✅ For laptops, press Windows + P (on Windows) to switch between display modes (e.g., duplicate, extend, second screen only).
Tip: A flickering screen could also be a sign of a low refresh rate. In your display settings, try increasing the refresh rate to 60 Hz or higher if available.
3. My Keyboard or Mouse Isn’t Responding
What might be happening:
- Dead batteries (for wireless devices).
- Loose USB cable.
- Driver conflict or software crash.
Try this:
✅ If wireless, replace the batteries or recharge the device.
✅ Unplug the keyboard/mouse and plug it into a different USB port.
✅ Restart your computer—sometimes a simple reboot can reload the drivers properly.
Tip: If it’s still not working, try the device on another computer. If it doesn’t work there either, the device may be faulty.
4. The Printer Won’t Print
What might be happening:
- Printer is offline or paused.
- Paper jam or low ink.
- Wrong printer selected in the software.
Try this:
✅ Make sure the printer is powered on and connected to your computer (via cable or Wi-Fi).
✅ Go to Control Panel > Devices and Printers (Windows) or System Settings > Printers (Mac) to ensure the correct printer is set as default.
✅ Open the printer queue to see if there are stuck print jobs—clear them and try again.
✅ Check the paper tray and ink/toner levels.
Still stuck? Restart both the computer and printer, and try printing a test page.
5. My Wi-Fi or Internet Connection Keeps Dropping
What might be happening:
- Router needs a reset.
- Too many devices connected.
- Weak Wi-Fi signal in your location.
Try this:
✅ Restart your router by unplugging it for 10 seconds, then plugging it back in.
✅ Move closer to the router or try using a wired connection for more stability.
✅ If possible, disconnect unused devices from the network.
Tip: Wi-Fi extenders or mesh systems can boost your signal if you’re working far from the router.
6. USB Devices Aren’t Recognised
What might be happening:
- Faulty USB port or cable.
- Outdated drivers.
- Device is not getting enough power.
Try this:
✅ Plug the USB device into a different port.
✅ Try the device on another computer.
✅ On Windows, open Device Manager, find the device, right-click and select Update driver.
Tip: USB hubs that aren’t powered may not support devices that draw a lot of energy, like external hard drives.
7. The Computer Is Overheating or Shutting Down
What might be happening:
- Dust buildup inside the computer.
- Blocked vents or fans.
- Running too many applications at once.
Try this:
✅ Clean dust from vents using compressed air (gently).
✅ Make sure the computer is on a flat surface with room for airflow.
✅ Close unused programs and keep background processes to a minimum.
Warning: Never open your PC unless you know how. If internal cleaning is needed, ask a professional.
