Help troubleshooting games crashing to desktop

I've recently built in the last week or so and am having issues when playing certain games where they'll crash to desktop and usually I have to open task manager to end them. My computer itself doesn't crash, and this only happens while gaming - which led me to think it's a GPU problem but I'm not ultra sure and after reading around a multitude of 'fixes' on the internet, I thought I'd post my specs here and get some help troubleshooting.

My (non OC) system is:
i5 4690k stock cooling
Gigabyte Z97M-D3H (replaced once cause first was DOA)
8GB Corsair Vengeance DDR3 RAM
Gigabyte GTX 960 Windforce 2X OC Edition
Kingston 120GB SSD
2TB WD HDD
Zalman 500w 80+ Bronze PSU
Single 24" Panasonic HDTV as a temporary monitor

My goal with this build was something small, cool, and low power to game with at 1080p only, with OC potential down the line - at which I'd replace the PSU and add cooling. Crap on the 960 all you want, but it's suiting my needs perfectly and I get 60fps easy on DayZ highest settings. And I guess that leads us to my problem.

I've done a clean install of the GPU driver, but can't update cause the 960 is still so new, so I've continued trying to investigate temperatures across my processors and various games.

My next line of inquiry are temperatures and at the moment I'm only really playing Day Z and Far Cry 3 while I wait for my next paycheck and GTAV to come out. When I play either game at 1080p fullscreen or windowed, it'll work really well for a while, with great fps etc, and then the game will crash to windows anywhere from 20 minutes play to two hours play. When I play at lower windowed resolutions where I can see HW Info, on both games the CPU and GPU stick around 55-60C, with the CPU sometimes spiking to mid 60s and I experience no crashes. When playing in full screen the GPU and CPU usually average mid 60s, and the CPU sometimes spiking to 70C. Since I currently have only one monitor I can't tell the exact temps when the games crash.

Last night I installed and played the original Half-Life and Portal, and played those in fullscreen and had zero crashes even after some hours. Then I installed Mirror's Edge and when I alt-tabbed while fullscreen to check temps the GPU maxed out ~60C and the CPU hit late 60s max but I can't remember the average. It crashed during the opening credit sequence after I had completed the training.

While these temps aren't exactly cool, they're not exactly dangerously high and I don't see why a game would crash after 20 minutes at them.

I don't really know how to continue investigating and at this point am just confused about whether it's hardware or software or cooling or whatever so I'd really appreciate some help even just being walked through how to get you guys some better info to help me.
