Green light on PSU simply means it has power according to one of our Rockstars. If any of the 1 2 3 4 lights would stay on, that would mean something. It would also mean something if the power light turned orange. It sounds like either a dead MB or PSU, more likely the MB, but can't diagnose from here.
A few things to try - reseat CPU and try it. Reseat RAM chips one at a time and try to power on after each one. Remember to unplug in between. If you can, make sure it's not the HDD. Those are a few things I would try before considering having a pro technician fix or a newer computer.
The T3600 is 7 yrs. old and the life of the CMOS battery is around 5. A low battery can cause all sorts of bizarre problems. If it's low, it's a cheap fix. Lithium is recommended vs. alkaline. I'd be remiss if I didn't mention it.
