DELL Latitude 3340 Stuck at DELL LOGO

Hello ! I need help for my Dell Laptop.

When I want to use the laptop the laptop doesn't boot and stuck at the DELL LOGO. I have done several attempt to fix this

1.Enter BIOS by pressing F2. But the screen only showed me "Preparing to Enter Setup"

2.Enter Boot Menu to run Dell Diagnostics by pressing F12. But the screen onlu showed me "Preparing for one time boot menu"

3.Press FN key to enter Dell ePSA, but the screen obly showed me "Diagnostic boot selected"

Please someone help me, because I need this laptop for my work.

Thanks
