Dell Dimension 2400 Motherboard Light?

Earlier this morning, when I turned on my computer. I noticed it was running slow, which wasn't happening the night before. When I opened it to see what was wrong, there was a green light on inside the motherboard for a few seconds. When I plugged it back up, and turned it on. I opened it yet again, to see the light was on again.

What does the green light mean? I searched a few similar question. The difference is that those people computers weren't booting. My boots, but what problem has occur to make the light come on? What solutions are there to fix those problems too? It was working fine until now...HELP!

    The purpose of the green light is to inform a technician that the computer is “hot” or that the power supply is currently supplying power to the motherboard and other components. This serves two main purposes. First, it acts as a safety device to warn the technician that there is a real threat of receiving an electric shock,

    Second, the green light on the motherboard can help a technician recognize whether the power supply is capable of supplying power to the computer. If the technician plugs the power supply into the motherboard and plugs the power supply into a wall socket and the green light doesn’t come on, the technician now knows that there is a power problem somewhere along the electricity supply line.
