Will Windows 8 force quit resource heavy apps if GPU is too hot?

[freelancer91]

So I have been having issues with Fallout New Vegas crashing to the desktop whenever I run it on high graphics (the default in my case). I just got done cleaning a lot of dust and hair out of my computer's radiator (it is water cooled) and out of my GPU's heat sinks. Here are my system specs

Windows 8 Release Preview x64
Intel DX48BT2 motherboard
Intel QX9770 Core 2 Extreme 3.2 GHz
BFG GTX 295 Single PCB
8GB of OCZ 1333MHz DDR3 Gold Series Dual Channel RAM
30GB OCZ Vertex I SSD (This is where the game and the save files are stored)
1TB Samsung HD103UJ HDD
The CPU is liquid cooled

I noticed that the computer is much quieter now, but I haven't tested yet whether Fallout will stop crashing.
I can run Fallout New Vegas on minimal graphics just fine without it crashing. It is only when I step it up a notch (even to medium) that it starts having problem.

Is it is in the nature of Windows to force quit a resource heavy program if something like the GPU is experiencing high amounts of heat that it can't dissipate?

Crashing is not done by the OS. If the card overheats, it will stop responding correctly and stuff will just start going wrong.
