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.

Computer beeps but no display
If I restart my computer, most of the time there will be no display but the lights are on and a single beep is heard which is normal. Why is this happening? I resolved it by removing the RAM slots and putting it back in but that's too much work and my pc is in a tough spot. Help?

I'd appreciate some help on this one. I'm a bit stumped as to where to go from here. I've had my PC for a year. It wouldn't wake up from sleep the other day - just a black screen. So I tried holding the power button. It wouldn't shut off. I had to use the power button on the back of the PSU. ...
