OK, here's the deal. I have a Toshiba P25 17" laptop. Whenever I perform a hefty task such as burning a DVD movie or converting large files, the laptop just shuts down. Now, normally, I would think just overheating, right? But, I don't think that's it. I have a large fan blowing directly under the laptop, and the laptop itself is on a notebook cooler pad with two fans built in. So, here's the different topics, let's discuss what could be the problem. 1. Overheating. 2. Cheap RAM - (I have a 1024mb stick of cheap-o RAM from NewEgg.) 3. Power Issue - Although my laptop can run without AC power, I always have it plugged in. But, it's plugged to a 10 outlet surge protector. COMP CREW, help me out here. There's got to be some pros here who can help me out.
