Q: My computer becomes unresponsive from time to time, which is frustrating. Why is this happening and what can I do about it?

It’s possible that one of the components in your computer has failed or is failing, which requires some technical know-how and spare parts to determine.
Bad sectors on your hard drive, a faulty power supply, a bad memory stick, or even something that’s plugged into a USB port can be the cause.
Detecting operating system and hardware issues is something that takes some tech skills, so if the easy tests don’t work, consulting an expert is the quickest way to get things working properly.
