When a laptop/computer doesn't get past the manufacturer's logo, then it means something is bad in terms of hardware or software.
If it's software, then Windows installation is corrupted. To attempt a possible recovery, restart the device and press the button assign to the Recovery mode. It will start in a safe environment from where you can restore the functionality of your device.
If it's hardware, then I recommend sending it to warranty (if it still has any period left) or visit a local PC service shop. The components that could be faulty are: RAM, HDD, Motherboard, or basically anything that's hardware related.
