Fix computer, laptop and internet problems with step-by-step guides for Windows, Wi-Fi, routers, browsers, peripherals, performance and reliable everyday connectivity.
Laptop LCD lines are usually a hardware problem, especially when they appear on the startup logo or change as the lid moves. Restart the laptop, compare the built-in screen with an external monitor, and check whether the lines respond to lid movement. If the lines remain, do not press the panel; arrange a cable or screen inspection.
“Sorry, there was an error licensing this video” means YouTube could not authorize playback at that moment. First test another video, then refresh or restart YouTube, check your connection, update the browser or app, and temporarily disable extensions such as ad blockers. If only one title fails, the video may be unavailable for your region, account, or device; do not try to bypass that restriction.
Use Windows Settings first: open System > Storage > Temporary files, review the categories, leave Downloads unchecked unless you have checked its contents, then select Remove files. For additional cleanup, run Disk Cleanup and clear your user Temp folder. Close open apps first, skip files Windows says are in use, and verify available space afterward.
Your laptop webcam is usually unavailable because its privacy shutter or camera key is off, Windows camera access is blocked, another app has control, the driver is damaged, or the camera has failed. Open the built-in Camera app to test it, then check the physical cover, permissions, app conflicts, drivers, and hardware detection in that order.
First test another device on the same Wi-Fi. If every device is offline, restart the modem and router, checking the modem first and the router second. If only Windows is affected, move closer to the router, reconnect Wi-Fi, restart the PC, and check DNS or network settings. Stop changing Windows settings when other devices also fail; contact your internet provider or network administrator.
To uninstall a Windows program completely, first save its files and close it. Open Settings > Apps > Installed apps, choose the program, and select Uninstall. If it is missing, use Control Panel > Programs and Features. Restart Windows, then check only the program’s own leftover folders or data; do not delete shared system files or registry entries.
To speed up a Windows laptop that runs slowly after startup, first disable unnecessary startup apps, then use Task Manager to find processes consuming unusually high CPU, memory, or disk activity. Restart after each major change, keep Windows updated, free storage space, and stop if the laptop overheats, shows drive errors, or remains slow in Safe Mode.
