How these guides work
Each guide starts with the fastest likely fix, then works through the real causes in order of how often they happen, with exact steps for Windows 11 and 10, Mac and phones. Each one links to the test that shows whether the fix worked.
Common fixes
Controllers that move on their own are covered in ps5 controller drift and how to fix stick drift. Printers that will not respond start with why is my printer offline. Keyboards that stop typing are in keyboard not working, and wireless earbuds that refuse to pair are in airpods not connecting. A silent PC starts with no sound on computer, a missing screen with second monitor not detected, and a drive or device that Windows rejects with usb device not recognized. Phones that stay at the same percentage are covered in phone not charging.
Not sure what is wrong?
Run the matching test first. The keyboard tester, mic test, sound test and webcam test show in a minute whether the device works at all, which tells you whether to look at settings or at the hardware.
