Lazer77, hibernation, I think, isn't good for the G74, for some unknown reasons yet to be revealed..
However, I've tried putting it into "sleep" mode for hours-many times, and no problems so far, when I"ve woken it up.
Have you tried the later nVidia BETA version (e.g. 306.02 version)? I'm currently on this version
(though I'm not a fan of BETA drivers) and all is well, until now.
