Diagnosing a crash

I've had crashes in two applications lately. Mechwarrior Online, and Wargame: AirLandBattle. Windows event viewer does not provide any helpful information and I haven't been able to set up heat, etc. logging software that saves information post-crash. Are there any recommended freeware options that let me do that?

The crash for both are such that the screen goes black, though the application appears to be running and sound pipes through for about 5-10 more seconds, then my computer restarts itself. So that suggests something at issue with the video card. Oddly, I can play entire rounds of both games without an issue, and sometimes upon starting the computer and trying to play either one, I will be plagued with crashes. To me anyway that suggests heat is not at issue, or the heat issue is manifesting strangely. It could also be a power draw issue, but again I am surprised at its inconsistency.

I am playing comparably graphically demanding games (Red Orchestra 2's latest release and Company of Heroes 2) and have yet to get crashes in those games. So thoughts? Does my video card only like world war 2-themed apps? I am fine replacing parts if I have to, but besides double-checking the fan in the video card is clean, how to narrow the issues? I'd have to buy a video card and PSU to test, so can't just test willy-nilly.

    In my experience a full system reboot is usually a PSU issue. GPU crashes tend to be hard freezes and are often accompanied by video artifacting

    thanks. Turned out the GPU was venting waste heat onto my CPU and overheating it - was able to fix it by either getting a better CPU cooler, or a new GPU.

    hm what does your case layout look like? Sounds like something you may be able to fix with better case ventilation

    Yeah, I had thought the reason that GPU cards were laid out "upside down" was to keep this from happening(?). Also, if you're willing to invest a little money and time, you may want to look into a H100 or similar all-in-one liquid cooler for your CPU. This would remove all heat related issues from the CPU.

    What I've done before was accidentally installed fan backward, right next to the PSU, so it was pumping the recently vented (and therefore hot) air back into the system. That caused the PSU to shut down. It was a completely facepalm move, but very easy to do. Just something extra to look at.

    While I agree that being insensitive is an issue, so is being oversensitive.

    Yeah, it's a small case, which i'm partial to. http://www.silverstonetek.com/product.php?pid=291

    Am keeping the $50 case fan, returning the HD 7970 and will upgrade the video card for real come next cycle.

    If that's the case, grab a 7950 or 760 and you'll be golden.
