Bad PSU or Motherboard?

Okay so the other day I took my computer apart just to clean all the dust out. After cleaning it I plugged everything back in and tried to turn the computer on. It flashed on for like a millisecond. I looked down at the PSU and I saw that the power cable to the graphics card from the PSU had been plugged right back into the PSU. Right after that I plugged it into the graphics cad and turned the computer on. Right when I turned it on I heard a little fizzle and smelled something burnt but the computer stayed on. But now it sends no signal to my monitor and I sit at a black screen. :( Could the PSU have gone bad even though it powers everything on still?

I have not tested with a DVM yet but I do have one and will test when I get home. I can also borrow a friends power supply later today as well. The power supply powers everything on that used to before the problem as well and I gave disconnected everything to take off extra load but I still get no video or audio output.
