  • How to Fix No Sound in Windows 11

    If your Windows 11 PC suddenly has no sound, the problem is often caused by the wrong output device, muted audio, a driver issue, or a Windows audio service. Try these methods in order.

    1. Check the volume and output device

    Click the speaker icon on the taskbar and make sure the volume is not muted. Open the sound output selector and choose the speakers, headphones, or other device you actually want to use.

    2. Check the physical connection

    If you use wired headphones or speakers, unplug and reconnect them. For USB audio devices, try another USB port. If you use Bluetooth headphones, make sure they are connected and selected as the output device.

    3. Run the Windows audio troubleshooter

    Open Settings → System → Troubleshoot → Other troubleshooters. Find the audio troubleshooter and run it. Follow the recommended steps and test the sound again.

    4. Restart Windows audio services

    Press Windows + R, type services.msc, and press Enter. Find Windows Audio and Windows Audio Endpoint Builder. Right-click each service and choose Restart.

    5. Check the audio device in Device Manager

    Right-click Start and open Device Manager. Expand Sound, video and game controllers. Look for your audio device and check whether Windows shows an error icon.

    6. Update or reinstall the audio driver

    In Device Manager, right-click the audio device and choose Update driver. If the problem started after a driver update, open the device properties and check whether Roll Back Driver is available. You can also uninstall the device and restart Windows so the driver can be detected again.

    7. Check the app’s volume

    If system sounds work but one application is silent, open Settings → System → Sound → Volume mixer. Make sure the affected app is not muted and is using the correct output device.

    Still no sound?

    Test another pair of headphones or speakers if possible. If another audio device works, the original device or its connection may be the source of the problem. If no audio device works, continue checking the Windows audio driver and hardware.

  • How to Fix a Black Screen on Windows 11

    A black screen in Windows 11 can happen after startup, after signing in, or while you are already using your PC. The cause can be a display driver, a temporary Windows process, a connection problem, or a startup issue. Try the methods below in order.

    1. Check your monitor and display connection

    Make sure the monitor is powered on and set to the correct input. If you use HDMI or DisplayPort, unplug the cable and reconnect it firmly. If possible, try another cable or another display port.

    2. Reset the Windows graphics driver

    Press Windows + Ctrl + Shift + B. Windows will attempt to restart the graphics driver. You may hear a short beep or see the screen flash. Wait a few seconds to see if the display returns.

    3. Try the security screen

    Press Ctrl + Alt + Delete. If the Windows security screen appears, select Task Manager. In Task Manager, find Windows Explorer. If it is listed, right-click it and choose Restart.

    4. Disconnect unnecessary displays and devices

    If you have multiple monitors, docks, USB display adapters, or other external devices connected, disconnect them temporarily. Then restart the PC with only the main display connected.

    5. Start Windows in Safe Mode

    If the black screen happens during startup, enter the Windows Recovery Environment by interrupting startup several times until Windows displays recovery options. Go to Troubleshoot → Advanced options → Startup Settings → Restart, then choose Safe Mode.

    6. Check the display driver

    If the screen works in Safe Mode, open Device Manager and expand Display adapters. Check whether the graphics device shows an error. You can try rolling back the driver if the problem started after a recent update, or uninstalling the device and restarting Windows so it can detect the hardware again.

    7. Run System File Checker

    Open Terminal or Command Prompt as administrator and run sfc /scannow. Wait for the scan to finish, then restart the PC.

    Still seeing a black screen?

    If none of these methods work, the problem may involve the monitor, cable, graphics hardware, Windows startup files, or another hardware component. If the PC works with another monitor or cable, that can help narrow down the cause.

  • How to Free Up Space on a Windows 11 PC

    Running out of storage can make Windows harder to use and leave less room for updates. These steps help you free space without deleting important files blindly.

    1. Check what is using your storage

    1. Open Settings → System → Storage.
    2. Review the categories using the most space.
    3. Open the largest categories to see what can safely be removed.

    2. Remove temporary files

    1. In Storage, open Temporary files.
    2. Review the list carefully.
    3. Select files you no longer need.
    4. Choose Remove files.

    3. Uninstall apps you no longer use

    1. Open Settings → Apps → Installed apps.
    2. Sort by size when useful.
    3. Uninstall programs you recognize and no longer need.

    4. Move large personal files

    Move large videos, photos, installers, or project files to another drive or trusted cloud storage after confirming you have a backup.

    5. Empty the Recycle Bin

    Open the Recycle Bin and make sure you do not need anything inside it. Then empty it to actually reclaim the space.

    Still low on space?

    Use the Storage settings to identify the largest category before deleting anything manually. This reduces the risk of removing files Windows or your applications need.

  • How to Fix High CPU Usage in Windows 11

    High CPU usage can make Windows feel slow and keep your fans running. The first step is to find the process using the CPU.

    1. Check CPU usage in Task Manager

    1. Press Ctrl + Shift + Esc.
    2. Open Processes.
    3. Click the CPU column to sort it.
    4. Watch for a process that stays high instead of ending it immediately.

    2. Check the app using the CPU

    If one normal application stays near the top, update it or close it and test again. Do not end Windows system processes just because they use CPU.

    3. Reduce unnecessary startup apps

    1. In Task Manager, open Startup apps.
    2. Disable programs you recognize and do not need at sign-in.
    3. Restart Windows.

    4. Scan for unwanted software

    1. Open Windows Security.
    2. Run a scan.
    3. Review detections before taking action.

    5. Check temperatures and cooling

    If CPU usage is normal but temperatures remain high, check airflow, dust, and cooling. High temperature is not always caused by high CPU usage.

    Still high?

    Identify whether the CPU load comes from Windows, one app, a background service, or security software. Changing one thing at a time makes the cause easier to identify.

  • How to Fix Windows 11 Blue Screen Errors

    How to Fix Windows 11 Blue Screen Errors

    A blue screen in Windows 11 is a symptom, not a diagnosis. Start with the easiest checks and use the stop code to narrow down the cause.

    1. Write down the stop code

    1. Note the exact stop code shown on the blue screen.
    2. Note what you were doing immediately before the crash.
    3. Look for a repeated pattern, such as a specific app, device, or driver.

    2. Install pending Windows updates

    1. Open Settings → Windows Update.
    2. Install available updates.
    3. Restart the PC.

    3. Check Reliability Monitor

    1. Search Windows for Reliability Monitor.
    2. Open View reliability history.
    3. Look at red X entries around the time of the crash.
    4. Note repeated application, driver, or hardware failures.

    4. Repair system files

    1. Open Windows Terminal (Administrator).
    2. Run DISM /Online /Cleanup-Image /RestoreHealth.
    3. When it finishes, run sfc /scannow.
    4. Restart Windows.

    5. Check recent drivers or hardware changes

    If crashes began after a driver update, new device, memory change, or other hardware change, test that change first. Prefer drivers from the PC or component manufacturer’s official support site.

    6. Use Safe Mode when Windows will not stay stable

    If normal Windows is repeatedly crashing, use Windows Recovery options to start in Safe Mode and remove or roll back the recent change. Avoid deleting system files or drivers at random.

    Still getting blue screens?

    Keep the stop code and crash timing. Those details are much more useful for identifying the underlying problem than repeatedly reinstalling every driver.

  • How to Fix Wi-Fi Connected but No Internet on Windows

    How to Fix Wi-Fi Connected but No Internet on Windows

    If Windows says you are connected but you cannot open websites or apps online, work through these steps in order.

    1. Restart your router and PC
