possibly the coolant gas has leaked out of copper pipe on the heatsink unit, maybe

Re: Acer 5742 overheating

trebo might be right. I had a laptop sent in to me for repair with that issue. It was reaching over a 100C on the gpu in about 5-6 minutes. Can you boot into a live os and tell us the temps?
Can you post a few pics of the cooler?
