I have a Toshiba Tecra, 256G HD, 4 G RAM. I have it partitioned for Windows 7 Ultimate, and Linux Mint 17.2. Currently, I am only having issues on the Windows side. When I am rendering a video in VideoMakerFX, at some points, the fan sounds like it's going into overdrive, everything stops moving, and then, the computer goes off. I will also have, if I leave the computer alone for more than 10 minutes, for whatever reason, it'll do the same thing...if I'm using Magic Jack, plugged into the laptop, and talking on the phone, it will still do the same thing. So far, I've taken to using a cooling fan, which helps, somewhat. If I'm not actively using it, like making a phone call, it still does that. I can leave it be, when I'm in Linux, and it hasn't had this problem, yet. Would simply using some compressed air help, or would I need to do something more?
