overclocking power failure? or power supply gone bad?

I bought an ibuypower desktop around 3 years ago and haven't had many problems other than a once in a blue moon blue screen or crash. However, for the last 3 days it's shut down a couple of times each day with errors about overclocking failures but had started back up with no problem whatsoever afterward. I don't remember the exact error message or code, but today I was playing world of war craft and the entire system shut off. No shutting down windows or anything, the entire power supply cut off(no popping no smoke no burnt smell as if the motherboard would if it had fried) I tried to restart it but the leds in it would flash for a second then cut off And the fans would not even start. The motherboard light was still on though. After waiting for an hour, I disconnected the graphics card and tried again and it hummed back to life with the motherboard beeping about the disconnected card.
My question is, would it be the overclocked settings causing the power to go out, or is it the power supply going bad? Since it's run this long with those settings it seems odd that it would cause it to suddenly not work, but if it's the power supply going bad it makes sense that it wouldn't be able to run the full load of the pc. As far as specific specs I don't remember the exact ones. I do have an i7 1st gen, Asus Saber tooth motherboard, Nvidia 560 ti, 6 gb of ram and the power supply is 700 watts. Any help is appreciated and sorry for the long post.

Usually under volted overclocked system show instabilities like BSOD or lockups or not fully booting into Windows. I have not seen one just cut off but I have seen them not POST after setting an extreme over clock so I guess it is possible.

Try resetting your over clock to stock and see if the problem persists. If so then yes I would look into your power supply or if you have a spare video card try running on the spare to rule the video card out.

Good Luck.
