Irregular BSOD when gaming

I have had an irregular BSOD where my laptop will just stop, die and reboot, notifying me of a blue screen error, while gaming. I have never had this happen when doing anything non gaming related. This happened quite frequently when I played Bioshock a month or two ago, and I thought it was something specific to that (older) game. I had experienced a couple of similar crashes over the years though. Recently I have experienced several crashes while playing a modded minecraft game. I assumed that the crashes were due to the mods, but when playing another game (The Walking Dead) I experienced another crash.

I have all windows updates installed and my GPU drivers are fully up to date using GeForce 344.11

I believe this is NOT a heat related issue, as I have run HWInfo64 logging temperature data during crashes and the CPU and GPU temperatures were both around 50C at time of crash, and the laptop did not feel warm. I have had some heat related crashes in the past, but I cleaned out the heat sinks and they stopped.

I was suspicious that the crashes might be memory or HDD related but I have run memtest86+ overnight for 8 complete passes (~16 hours), finding no memory errors, as well as running a full checkdisk, also finding no errors. The reason I suspected the memory or HDD was because the crashes may have been occurring when crossing a chunk boundary in minecraft, which I assume would be causing loading.

At this point I feel it is most likely to possibly be a graphics card related issue, as I have been playing another game, Factorio, which is 2d (although I believe it does use the GPU for drawing) and uses lots of saving and loading of game data without issue for a couple of weeks, but multiple crashes occur in different, not very intensive, 3d games in the same day.

I have hopefully attached the DM log output. Any advice?

EDIT:

I tried using OCCT in the GPU test mode, and my laptop crashed almost immediately. This makes me think that the problem is in the GPU...

I have run some tests with OCCT 4.4.1 using the GPU testing features, and if I run it in DX11 mode, it crashes immediately. Running in DX9 mode it ran successfully for 3.5 hours.

Does anyone have any experience with anything like this?

I have further narrowed the problem down*. It appears to be a power related issue. When I set the laptop to balanced mode then the test runs in DX11 mode without crashing. If I run with or without AC power plugged in, the test will run without crashing in balanced mode. If I switch to high performance (which might only be possible when running on AC power) I get an almost instant crash.
