Hi @nabilelshall,

Welcome to the HP Support Community. 

I'd like to help!

To be able to answer you effectively, we need some information.

Have you made any changes to your pc hardware or software?

Remove discs and devices and perform a hard reset

Before troubleshooting startup issues, remove or disconnect all discs and devices from the computer.

• Turn off the computer.
• Disconnect the AC adapter.
• Remove any discs from the disc drive.
• Remove memory cards from the card reader slot.
• Disconnect all nonessential devices such as printers, scanners, external hard drives, and USB flash drives.
• NOTE:
• Do not disconnect your mouse, keyboard, or monitor.
• With the AC adapter unplugged, press and hold the power button for approximately 15 seconds.
• Reconnect the AC adapter, and then turn on the computer.
• If the computer starts, reconnect the devices one at a time to determine which disc or device is causing the problem. Continue with the troubleshooting to test the hardware for failures.
• If Windows does not start but the screen turns on, continue with the troubleshooting to test the hardware for failures.
• If there is no noise from the computer case or fans, the lights on the computer do not turn on (including the keyboard lights), and the screen does not receive a video signal, your computer might not be receiving power. Contact HP for further support.
