Friend's computer died. I took it home to fix it. I'm lazy, so it was gonna take me a few months to get to it. I lent them my Athlon 650 box, which was about twice the power of what they handed to me.
I fixed theirs, eventually, and they decided they liked mine better. Had no use for it at the time so I said they could use it but return it if they ever decide to get a new machine.

I hung out with them today (they're getting married btw) and was told that the machine caught fire. WTF?! Upon further explanation, here's what happened.

The computer was turned off. Joe hears a loud pop. Rachel then smells something burning and thought Joe was cooking. Then the smoke starts to show. Joe opens the case and smoke pours out. Puts the machine outside until its done smoking. Machine no longer turns on. duh!

Now I have it back. Inside the case everything looked ok and intact. I took the PSU apart and some pieces of capacitors fell out. I figured it was the PSU blew, but the machine wasn't even turned on. I hooked up a new PSU and still cant get it to turn on.
If I hold the power button on the case for a few seconds then flip the switch on the PSU to turn it on, I get a small jolt of power. Just enough to light the fan and make it spin half way, but I can't get it to stay on.

The PSU that blew was a 250w Deer Computer PSU which came with some generic case about 8 years ago.

Any thoughts? Because the machine was turned off, I dont see how anything could've gotten damaged.

They don't fully turn off unless you cut the power to the power supply. Some stuff carries on running. Mine for instance powers the nic, usb ports and god knows what else.

By way of demonstration, he emitted a batlike squeak that was indeed bothersome.

Not only that but the Capacitors inside the PSU can stay charged for hours. Sounds like either a old and overused PSU or a damaged product.
