Power surge damaged a PCI slot, will it spread?

I'm pretty sure that it will not. A similar thing happened to me but both the card and the slot were dead. The rest of the system worked until it was replaced some years later.

"As always, each case is a little different. I once had a sound card that bricked itself; in the process of it expiring, every other item on the PCI bus lost its magic smoke, too. A couple of other PCI cards, as well as the on-board devices that were part of the bus. CPU and RAM survived, the drives themselves survived, but the MoBo was a total write-off.

In my case, though, it wasn't an external event; at least, I don't think. Whatever caused the caps (all of 'em) on the sound card to pop just ranged through everything it could get to electrically.

That was, officially, my weirdest ""massive failure."""
