UPDATE
IST just got back to me after looking at the notebook. The GPU is fried due to my overclocking. So I sugget you all to not overclock, and if you must, do not push it. The cooling in this notebook for the GPU can generally not handle the overclocking.
I have a cat, and I've never really though about it, but the hair actually gets into the mobo, the fans and everything. My cat is not going anywhere near my notebook again!
