Signs your computer needs a technician (and what to try first)

Computers rarely fail all at once. They usually give warning signs first. Knowing which ones you can fix yourself and which need a technician can save your files and your money.

Try these first

1. 1Restart the computer properly, not just close the lid.
2. 2Install any waiting system updates.
3. 3Free up storage space; a nearly full drive slows everything down.
4. 4Uninstall programs you do not recognise or no longer use.

Time to call a technician

• Clicking, grinding or new loud noises. This can mean a failing drive. Back up immediately and stop using it if you can.
• Overheating or sudden shutdowns, often caused by dust or a failing fan.
• Pop-ups, a changed home page or programs you did not install, which can be signs of malware.
• It will not start, or shows error messages on start-up.
• A swollen battery, where the case bulges or the trackpad lifts. Stop using and charging the laptop and get it looked at, because damaged batteries can be a fire risk.

Repair or replace?

Upgrades such as a faster solid-state drive or more memory can make an older computer feel new again for much less than a replacement. A good technician will tell you honestly when a repair is not worth it.

Before the repair

• Back up your photos and documents if the computer still works.
• Write down what goes wrong and when it started.
• Have your passwords ready, especially for your email account.
