Look at the description for the diagnostic lights on a Dell 2400 here under "A possible expansion card failure has occurred."

If you have recently installed any card (wireless, sound, etc.), then this would be my first suspect.

The screen on my dell 2400 desktop flash but won't come on


Remove the video card from the computer and connect the monitor to the integrated vga port, check if that helps, or else look at the back of the tower or on the front you would find four diagnostic lights, post the status ot them

LED trouble lights


the led lights you see is actually a diagnostic light which has an equivalent meaning there should be actually 4 led lights you see is it a yellow green green green pattern and this is at the back of your computer? if that is the case it could be an indication that there is a device inside your computer that is malfunctioning. you will have to strip down your computer. remove all that is connected to the motherboard (hard drive, cdrom, memory, expansion card if any) disconnect the mouse, keyboard and monitor as well. should you hear a beep or the light changed at the back it means your motherboard is good and the absence of memory is being reported by the beeping sound. try to connect the device one by one
now if you are referring to the light at the dell logo infront it is just a monitoring light to indicate if your computer is turned on and the right side light is whether your hard disk is doing an activity
