My HP pavilion xt963 was working fine until yesterday. The computer was off and when I pushed the power button nothing happens, no lights, noises, beeps etc. I have checked the power cord and there is a green led light lit on the back of the pc. Is my power supply bad, can it be worse?

The first 2 things to check is the power supply and the on button switch that turns on the computer. To check the PS i usually keep a known good spare one around and just plug it in without placing it in the computer. Try borrowing a good one from any friends you have( surely you know at least one computer geek, dontcha). I don't even hook everything up, just motherboard, hard drive and video card if needed. All your trying to do is see if it will boot at all. You can check the switch by pulling the 2 wires and jumping the pins with a small screwdriver. Be careful here to not hold the screwdriver on the pins very long. This is a momentary switch which just tells the motherboard to power up. 1 second should do it. You will have to figure out what wires are for the power on switch. I usually down load the manual for every motherboard, from the MB manufacturers website, that i have so i can find this sort of thing out. If you need a new switch, directron.com has new micro switches in stock.
