My brand new laptop doesn't see the graphic card anymore

[Cimiur]

Hi everyone,

I have just bought a Gigabyte P35W, which has worked well for only 24 hours.
Today i launched a game from steam, it crashed, task manager wasn't able to end it and so I tried to restart. After the OS was shut down, the pc stayed with black screen for like 2 minutes, so i decided to hold the power button for 8 seconds. After that now it works but it doesn't see the graphic card at all, I have tried to install again the drivers, but it says that it can't find the hardware.
I have Windows 8.1 and a nvdia geforce gtx 970m.

Help me, please!
Thanks in advance.

Is your graphics card visible in the device manager?

 

[Cimiur]

No it isnt.

Then check it in the BIOS.
Also update the BIOS.

In the BIOS I can't see any graphic card, and after the BIOS update nothing has changed.
I tried again to install the graphic card drivers (downloaded from the gigabyte site) and the installer says: "the graphic drivers could not find compatible graphics hardware".

Better you give it to a service center then.
