Suddenly bad PS

I unplugged my power supply to clean up some wires, and when I plugged it back in it suddenly wouldn't start.

After some tinkering, it would sporatically try to start itself spastically, but that's all I could get...

It's a Dell Dimension 4600. I called Dell and they weren't much help. Any ideas?
 
Get a new PSU, it has to be Dell compatible I think... Something they do to the hardware makes psu's that aren't Dell compatible not work, but I don't know that for sure correct me if I'm wrong.
 
Most if not all "black" dells are standard ATX PSUs now, so I don't think that's much of a problem anymore. Are you sure everything is plugged in correctly? Check all the connections, and then next try running with just the bare minumum outside the case, CPU, mobo, RAM and GPU
 
I checked the connections several times and even went through the process with the Dell guy. Nothing turned up.

The biggest question I have is how it could be working perfectly, to suddenly not working at all in a span of only a few minutes. What could have caused that?
 
OEM power supplies are usually $10 pieces. And they are open to the environement. Any dirt getting in there can shorten out something important, quite often under interesting sound and smell development. PSU dieing is a very common phenomenon, nothing that should surprise you. The big question is always - did it take out anything else? One spectacular event I witnessed (and performed the autopsy on) took out every last piece connected to the 12 V rail, MB, all drives including CD and floppy, the only things alive were the CPU and memory.
