I replaced the power supply with a dynex 520 watt atx that says its compatible with intel and amd multicore processors. Still nothing. There is a light that comes on on the motherboard when I plug it in. Do you think I have the wrong type of psu or is my mother board fried. Im not much of a computer tech but I can unplug and plug back in so changing out the power supply was easy but beyond that im lost. Thanks for your help.

Yes everything is plugged in, I triple checked. Nothing else has been upgraded. At this point I do not know if the old psu stopped working or if it was something else. I assumed it was the psu when nothing happened when trying to turn it on.
