Computer "blocked".

[Eyesee]

I have a big problem with my computer.
In fact, I lighter and randomly hang (as if we had done a screen) mouse and keyboard do not respond. It may be blocked after 10 seconds on power as after 2min. Once I even had time to listen to music and even launch internet.

It hangs in safe mode as in normal mode.

When it works 2min, I can have access to hard disks and used the file.

I did not see at all where that might come.

My computer is brand new and powerful.
If you want more information ask me.

Thank you in advance for your future and help
