Fan RPM's are no longer automatically changing! Help Please

[Morphic]

I have noticed that recently my computer was shutting down when under a heavy load from a CPU/GPU intensive process. I reapplied thermal compound to both the GPU and CPU to make sure that wasnt it because I couldnt think of anything else. I did drop the temperature by a few degrees but it still shut down. Then I noticed that while my fans were still spinning, they continued spinning at a very low RPM and not increasing as the CPU or GPU load increased. Even when I overclocked my PC with TurboGear it would usually be VERY audible when the RPM increased, now it does nothing ( stays the same ). What could be going on here guys? By the way this is a laptop with 4 fans along the back ( Made precisely for gaming and has never had any problems until now. )

Intel core 2 duo 6700

2 gigs DDR2 Corsair ram

Nvidia 8600GTM

when you first had it did it come with any fan profile software?

have you since reformatted the machine?
have you 'cleaned' the startup programs and possibly turned it off?

No sir this is not the first time I have formatted this computer either ( I actually format about every 4 months or so because there is nothing but games on here ). I have a cd that came with the computer and it comes with all of the programs that came with the computer originally and I just looked through them to no avail. There is a overclocking program called turbogear that game with it, and when I used to turn it to gaming mode the computer sounded like a monster when the fans revved up and stayed there, now they stay the same speed reguardless.
