Alright, it seems I can't determine the exact cause either.. Will look into replacing the GPU, is this possible on a laptop with the NVIDIA Quadro FX? I have only replaced them on desktops before.

I've been asked a similar question before and I can't answer because it depends on the motherboard, most likely no.
However you can ask here and they may give you an answer.
I don't have much time to go looking for which GPUs are compatible.
