If your device occasionally fails to start normally, you can refer to the following steps to solve it. Let's take a look.

In this case, we can try to update the antivirus software first. It is also recommended to update your Windows system.

Also, peripherals can interfere with the Windows startup process, so the next step is to remove all peripherals.

For desktops, you'll also need to remove the monitor, mouse, and keyboard. Then remove the power adapter and battery. Press and hold the power button for about 15 seconds, then connect the adapter and battery back to the computer, and restart the computer to see if the problem is resolved.

If the problem persists, try running the Diagnostic Hardware Test to see if the hardware is faulty.

Resetting your computer's BIOS to its original factory default state is also one way. Restart the computer, turn on the computer, and after seeing the Dell Logo, press F2 several times to enter the BIOS interface. Different system versions will have different reset steps.

For most newer versions of the system, you can directly click the LOAD DEFAULTS option, and then exit to complete.

The other is to click the restore settings button and then exit.

For older versions, you need to use the F9 key on your keyboard to initiate the step to load the defaults, confirm and exit.

The next method is to reset the Windows 10 system through the Windows Recovery Environment (Windows Recovery Environment) and reinstall the corrupted system files. Normally, after the third failed boot attempt, the Windows 10 system automatically enters the system recovery environment.

On the screen for selecting options, click Troubleshoot, select Reset this computer, select Keep my files, then select your account, enter the appropriate password, and select Continue with reset.

If the problem persists, try restoring the computer to its original factory state.
