pc frozen, black screen with green stripes

Hello :wink:

i have this problem regularly : while using the pc suddenly pc is frozen and screen becomes white or black with green stripes…
I therefore can’t do anything with the keyboard nor mouse. Not even killing X, nor go to virtual terminal or rebooting, even using the “magic keys” way ( https://en.wikipedia.org/wiki/Magic_SysRq_key )

Where can i have a look to identify this problem ?

thanks :wink:

here’s what i’m using with gui being kde 4.10
