Computer randomly shutting off

My computer keeps shutting off randomly. It seems to have been working all week just fine. I didn't install any new software or hardware either so I'm thinking it is a hardware issue.

The computer shuts off about 15 mins after I'm using it, especially when I'm playing World of Warcraft. I check my video temperature and it's at 49 degrees Celsius consistently when playing the game. However, this morning my computer was shut off, and I didn't have any game running on my computer over night.

The event logs aren't indicating any problems what I can see at the time it shuts down. I'm not even sure what to look for in the Event Log that could be causing this. I ran WhoCrashed but it said there's been no crashes on my computer. My temperatures seem just fine consistently too. Could this be my power supply going bad or unable to support it? I mean it's been working fine for a week since I built this system.
