Follow these guidelines:

1. Turn a power-off computer on or reboot a running computer.

2. Quick press the F8 key on keyboard before Windows starts, after hearing a beep sound you will be taken to Windows Advanced Options Menu instead of the normal loading page. If it doesn't work on the first try, just reboot and try again. And Select normal loading option.

Fix windows internal errors and corrupt registry to avoid such types of errors in future. I would suggest to use system utility tool Reginout.

Go to control panel click on sound then on speakers. After clicking on speakers click on set as default at the bottom.

1, Disconnect the power cord and switch off the computer. Tap and hold the power button for 5 seconds.

2, Switch on the computer and reconnect the power cord. Turn on the computer and tap the F10 key for about every 5 seconds.

3, Press the F5 key and this restores the default settings. Tap the Enter key for the changes. Press the F10 key for opening the Save and Exit window.

4, Tap the Enter key and this saves the changes and restarts the computer.
