Power Supply Dying?

[Homey D. Clown]

I'm thinking my PSU maybe dying, Was Playing stalker when suddenly my computer just shut off! Hit the power button and it started up fine but I haven't tried playing a game yet.Spec are in my sig, Power supply is a enermax noistaker 485W that i've actually been using for a few years now. Was overclocked to 2.52. So you guys think it's my PSU or something else? Running Windows Vista Home Premium 32 bit if it matters.

If you booted up in windows, it might be drivers, just update them and then see what
happens when you are playing a game
