As you know, something burned out (literally).
The most likely suspects are the power supply and the motherboard (a component on the motherboard).
If you can borrow a compatible power supply from someone you can hook it up to test.

If it is not the power supply then you are most likely looking at a new motherboard. And since this is 7 years old there is a good chance you will not find a new replacement.
It could be time for a new (or new used) system.

Along with TVeblen's ideas, also check your monitor on another PC to test it. If you have only onboard video I also suspect the board is bad. Look very closely for anything that looks burned or bare copper traces.

PC powers on/off during boot, wont complete boot
It's a friends pc. I replaced the power supply but that did not fix it. It's not a virus cause it did allow me to install linux. So the cd rom worked through the install. The computer has a lot of dust in it. I was going to blow it out tomorrow. Could it just be dust? Any other ideas.
