Shutting Off Problem

[scorpio]

For some reason my computer just randomly shuts down, but the power supply is still on and I know this because my keyboard's lights are still on. Until I pull the plug and the capacitor wherever it is loses power and the lights on the keyboard goes out, can I turn my computer back on. What's going on?
