Call of Duty 2 "stop error"

[rumncoke81]

Just wondering why my computer restarts when I am halfway through the British campaign of the game. I finish off one section, and then it is loading into the next section, I believe it's the one where you are driving the tank for the first time, and as it is loading my computer shuts down and re-starts. When it comes back to my desktop is says that windows has encountered a "stop-error" and it has to do with a device driver that I have installed. I was thinking that it is my video card, seeing that I recently purchased a new one, but it doesn't do that for any other game that I have, i.e. F.E.A.R., HL2, Doom 3. So that is why I am thinking that it has to do something with the game. I tried looking for a patch but the only one I could find is for a dual-core processor and I do not have one.
Anyways, if anyone could help me with this it would be greatly appreciated.

Processor- Intel Pentium 4, 2.4
Hardrive- 120gb
Ram- 1024mb
Video card- Radeon 9800 pro, 128mb
