Weird Hardware Experience
 
I have an internal network in which 9 labs are connected to. Each lab has 3 computers. These labs are connected but are NOT mounted to each other. One lab can be off and all others be on with no issue.

In a single lab, one computer's serial PCI had somehow stopped working causing the computer to shut down. Every time the computer was turned on it started making a clicking noise. I came to the conclusion of the PCI being broken, by replacing parts one by one and after replacing it, the computer booted.

The weird part is that every computer on the network froze when the one computer powered down. Is this something normal? An anomaly? What would possibly cause this?

I am not looking for a solution, just possible reasoning why this might happen for preventative measures.

Did you forget to put banana peels in the flux capacitor? That'll do it.

It's going to be really hard to determine, you only say PCI was broken? Was this a PCI expansion card? The PCI bus on the motherboard itself? What was the actual piece of faulty hardware? Was there any connectivity on this PCI or any PCI device running on the system? If so, which devices were on the network when the hardware fault occurred?

That's going to be some good info to help us give you some possible causes.

I apologize for my poor explanation. It is hard for me to sufficiently explain hardware as I am more involved with software.

It is an external PCI plugged into the motherboard. It was running an external monitor that was used as a separate display. This network is a wired network that runs 9 labs of 3 computers. [EDIT] These computers are all configured exactly the same.

My main issue is not the PCI breaking but that when it broke and the computer shut down prematurely, why would that make all the other computers on the network to freeze?

Well the only thing that could make sense is that there was a surge on the network cable that caused the switch to die. I mean there are probably other causes but based on the info provided a surge in the cat5e cable plugged into the motherboard sounds probable, the integrated ethernet card on your motherboard will use the PCI bus as well so if the bus surged it might have gone out over your network connection.
