- The Caps Lock key is illuminated when toggled
- The hard drive activity light may flicker, stay on or be off

Verify the computer finishes initial power-up (POST)
In many cases, a computer will not attempt to hand off control to the operating system. If you power the computer on and you see a CyberPowerPC logo screen or Motherboard manufacturer's logo screen with a bar at the bottom, and that bar fills up completely and disappears, then your computer has successfully completed POST.

Unplug all external devices and perform a hard reset
A piece of hardware may be interfering with the normal boot process of Windows. Try unplugging all devices from your computer, including:
- Media Card Readers
- Small Media cradles (iPod, PDA, MP3 player, etc.)
- Digital Cameras and Video Recorders
- USB storage devices
- CDs or DVDs from all optical drives
The only devices you should leave attached to your computer are your monitor, mouse, and keyboard if the computer is a desktop.
Once this is completed, unplug the computer from the wall, remove the laptop battery (if applicable) and hold the power button down for approximately 15 seconds. Then plug wall power back into the computer and attempt to restart.

If you are experiencing a blue screen error on your computer, refer to Windows 10 crashes to a blue screen for common blue screen errors and how to troubleshoot them.
If you are experiencing a black screen that will not go into Windows, refer to Microsoft article Troubleshoot black screen or blank screen errors.
Reset the BIOS to default values
If your computer is set to first attempt to boot to another device, this may cause issues with successfully booting to Windows. To reset your computer's BIOS to factory defaults, perform the following steps:
- Restart the computer
- At the CyberPowerPC logo or Motherboard manufacturer's logo during restart, tap the F2 key repeatedly until you see Entering Setup in the top right corner of the screen.
- Depending on the BIOS, you may need to press a key listed at the bottom of the screen to load default settings.
- Press ESC to exit the BIOS, and be sure to select Save and Exit to save your changes.
Note: For Windows-based tablets, perform the following steps instead.
- With the tablet completely off, press the Power Button, and then immediately press and hold down the Volume Down until the System Setup page (BIOS) appears (if the tablet boots to Windows, try again).
- Touch or click Load Defaults.
- Touch or click OK.
- Touch or click Exit, if the tablet does not automatically reboot.
A corrupt BIOS is one of the possible causes of your PC unable to complete POST or sometimes even boot into the operating system.
Safe Mode Troubleshooting
The software may be causing your system to not boot properly. For more information on booting to Safe Mode, and to troubleshoot using clean boot troubleshooting, refer to the following links:
Clean boot troubleshooting
A clean boot is performed to start Windows by using a minimal set of drivers and startup programs. This helps eliminate software conflicts that occur when you install a program or an update or when you run a program in Windows 10. You may also troubleshoot or determine what conflict is causing the problem by performing a clean boot.
Virus and malware troubleshooting
Your computer may be affected by a virus or other malicious software. CyberPowerPC recommends strengthening your PC against malicious attacks by keeping your antivirus software up-to-date.

- At the Choose an option screen, select Troubleshoot.
- At the Troubleshoot screen, select Reset this PC.
- At the Reset, this PC screen, select Keep my files.

Restore the operating system to factory settings
If the previous troubleshooting could not resolve your issue, it may be necessary to restore your computer to factory settings.
