I recently got my g400 and when I first turned it on I heard a fairly loud pop, but it worked ok, used it for the rest of the day, a few hours, turned it off over night. I woke up today, turned it on, VERY loud pop, monitor is dead, just funky colors. Has this happened to anyone? I got it from staples so I can easily rma it at no cost, but it just sort of annoys me. I mean is this a commond defect, or something I could of done?
