PC shuts down suddenly when playing game

[Flasharino]

This has happened several times over the past couple days. I will be playing DC Universe Online and my Windows 7 x64 PC simply and abruptly shuts down. Not blue screen, nothing just power off. I have had the system for years and never seen this happen under other circumstances. I don't know how to figure this out at all. I don't know where to look and I don't even know if it is a hardware or software problem.

Any help is appreciated.

Id firstly check your temps - if the CPU or GPU gets too hot it will shut your computer down to protect it. Software such as Real Temp & GPU-z may shed some light on any overheating issues
