Last summer i bought myself a shiny new Macbook Pro 15,4" - for studies as well as some gaming via Bootcamp.
First off, I started and finished Half-Life 2 and then some Civilization IV. All was running well on high settings, and there were no stability problems at all.
However, when i bought and installed Battlefield 2142, and Rome: Total War, things changed.

Within minutes - most often after 20-30 minutes of gameplay - the MBP would just shut down. No blue screen of death, no error message, nothing. Just a black screen, then it reboots itself. At first i thought this could be a thermal shutdown, but the computer does not have to be any hot at all.

Possible solutions tried:
- Updated GPU-drivers
- Omega-drivers
- Underclocking the GPU
- Overclocking the GPU
- Adjusting fans to high speed at all times
- Playing next to the window
- Resetting PSU and PRAM
- Settings in the games affected
- Full reinstall of Bootcamp, windows and drivers

The shutdowns only occur when playing games. When doing benchmarks or scanning for artifacts it runs like a dream for hours.

I've really run out of ideas now. Could it be faulty hardware?
Anyone else experiencing this?

I have had this happening to me a few times also, only in Command & Conquer Generals Zero Hour though and only in multiplayer games - so far it hasn't happened often enough to narrow it down much, it could just be that particular map for all we know at this point.

If it happens more I have the omega drivers downloaded and ready to test, but I would also be interested in seeing if anyone else has the same issue and figure out why it happens.

EDIT: Another search on these boards revealed this thread (http://forums.macnn.com/104/alternat...-freezes-gpu/), will try that before anything else then if the problem persists Sorry about not searching more before posting
