It appears as if your power supply is dead. The power supply is inline with your power cord and has a light on it, if I am correct. Since the green light was dim, then went out all together on your power supply, that would indicate that it would not take a charge any longer, and the dim light, down to none, was the rest of your battery draining. Assuming you tried multiple power outlets, my suggestion would to borrow a power source from a friend and check it, or go to best buy/Apple store and have them use one of theirs to see if it comes on.
Yes even with the green light on it could still be the power supply. Have you pulled the power, opened the case, and pulled the BOIS battery? Could be the BOIS needs to be reset. You might also pull all the memory chips, turn it on and see if you get a beep code. I have had that happen in the past. Then I would replace the power supply (if you have an old one laying around use it to test, with just the MOBO plugged in). If the power supply fails, that leaves only the mother board as the issue.
Good luck, I hope one of these suggestions works for you.
Do you mean the monitor's power light starts green and then turns orange when you turn it on? Most monitors will go to a power saving mode when they do not get a signal from the computer.
The Dell GX260 has a green power light when on. When the computer is off, the light is off. If it is green and blinking, then the computer is in a power saving mode.
Diagnosis: start with the obvious: is the monitor cable plugged into both the computer and the monitor (if not permanently connected to the monitor)? Are you connected to the active port? (You can add a video graphics card in most desktops. The motherboard video port usually needs to be disabled to use the card ports. If you plug in the monitor cable to the disabled port, it won't work.) Is the monitor set to the correct input? (This applies if the monitor has several ports. In that case, there will be a Source or Input button on the monitor.) Is the computer on? The GX260 has the power button on the front. (Other computers have the power button on the top.) There is also the power supply switch on the back which needs to be on.
Next try a different data cable between the monitor and the computer (if you can). Try a different monitor. If a second monitor works, than the monitor has a damaged main board. If the second monitor doesn't work, then the video graphics adapter has probably failed. Replace the add-on card, if in use, then boot in the safe mode to remove the old graphics driver. Then install the correct driver for the graphics adapter.
Note: the computer and the monitor should both be off when you connect the cables. Then turn on the monitor first and set it to the correct source before turning on the computer.)
Hold Power button in for 10 secs... see if starts... if not, unplug for 5 min and plug back in and try to start. Motherboards can lock up in the BIOS or it could be a power supply. If this solution doesnt work, leave power plug out over night and attempt again. If fails again... it maybe the power supply.

You will need to replace the hard drive which has any version of windows operating system, or you will have to re-install windows xp on that computer. Assuming if the computer has a green light and monitor has an orange light. I've encountered this problem where I work at.
