Stuck on VAIO screen after starting

[vinbocqu]

Hello,

I've a vaio SVT1312C4E Ultrabook with Windows 8.

After starting, it's stuck on the "VAIO" screen. I've tried the function "assist", disconnected the battery for few minutes, ... but it's still the same.

The hard drive stops working after displaying this VAIO screen.

Thanks for your help.
