Game restarts my pc

[helmcken]

I have been experiencing similar problems as discussed in this post. Basically the game will cause my laptop to shut off power altogether! This happens any time after the opening monologue where he says "My name is....I am____" and always happens by the time I try to move the mouse to look around. (I must say that this same thing happened when I tried to play Penumbra! After a few minutes play, the game would suddenly snap the power off completely! Never did solve that and have yet to enjoy completing the Penumbra series! Now, Amnesia is doing the same thing!)
I have also tried all the suggestions. I have updated the nVidia drivers, applied the newly released Amnesia patch, gave write permissions, tried lower resolution, lower settings in general, rebooted after every change and only changed one thing at a time. I have uninstalled and reinstalled. I do not believe it is overheating; it feels cool enough to my touch. The folders I can see in "My Documents/Amnesia/MainDemo" are only Garrett(my character's name), hpl, hpl_update and main_settings. I do not have Windows Aero installed. This is a 2006 HP pavillion laptop running (dual boot Ubuntu and) Windoze XP home. I have tried turning the Telus Anti-Virus/Anti-spyware program completely off, pulling the wired internet connection plug physically out of the laptop and shutting off as many background services as I can- especially all the auto-updaters. I do a lot of work preparing the computer to play Amnesia, so this is frustrating that it still is not running.
PLEASE HELP!!! Here's the hpl log output from the "MyDocuments/Amnesia/MainDemo" folder:
