I have changed my notebook about a week ago, I have installed 10.10 and every once in a while, the screen goes black but just for a fraction of a second. I have tried disabling Compiz, update drivers with latest Nvidia one but no luck.

Note that this does not happen on Windows at all and that there is someone else that has the same notebook and same issue on 10.10.

Any ideas of what I should try or look at ?
