Hardware Crash after install 3 times

Hello @all

Today i became my new Celsius H270 and i installed SuSe 11.0
After install i make all updates and then i to an reboot.
Grub came up and he begin to boot but after 4 seconds the system hang with a black screen.
I press the powerbutton for 4 seconds and i start again!
No Bios nor boot!

This is not the first crash!
My frient have the same book with the same nvidia card (m770).
And he have the same troubles second times.
The hardware is different at CPU RAM DISK
The only things which are the same is the mainboard and the nvida card!
The book is now at repair!
At my friends book they must change the mainboard! (Now he runs it on vista :’( ) and have no troubles.

Have anyone the same troubles?

What can i do to run SuSe on it?
