So, a friend's machine abruptly shut off today and wouldnt come back on. I took a look at it and my first thought was that the PSU died.

I removed the PSU and smelled it... plasticy.
I did the wire trick to see if the fan would run... Notta.

I had an older 450w PSU (This is enough to run the machine) lying around so I donated it to them. Before installing it, I did the wire trick and the fan spins (aka PSU isnt dead).

Installed.
All wires plugged in...
Powered ON: LED Fan lights up, spin for 2 seconds, Computer shuts off.
Can't get it to turn on or repeat this.

Removed the PSU thinking I somehow blew that one... did the wire trick... fan spins.

So... its not dead but it won't boot.

Will case fans spin even if the motherboard is kaput? I tried just plugging in case fans to the power supply - Notta (But I assume they need motherboard... why I dunno... but *shrug*.

The PSU im using is older and Non-Modular.
Could the wires themselves be bad but the PSU be good?! I'm so confused... Help Please.

SOLVED: I went out and purchased a brand new PSU and set it up.
At first it did the same thing: Bios came up... then it shut off.
All hope was lost... until I realized the heatsink fan was loose *facepalm*.

After that it posted and stayed on.

Reconnected everything again... and it booted right up.

(So my ol generic 450w PSU works... but I feel better with the brand new one in there so *shrug*.)

Anywho, Thanks Hellfire.
