Hello,

My PC stopped working a little while ago, and I think the power supply went out, but I'm not sure. It will not power on at all, but the light on my motherboard is still lighting up. Is this most likely a problem wih the power supply?

I'd have to say that it's the power supply, but it could (though no likely) be a problem with the switch.

When you hit the button does the power supply fan start spinning, or does it just sit still while the motherboard light remains on?

The power supply does nothing. The fan does not spin. So that means that it is the power supply?
