I have a wired Belkin NIC card that vanished from Device Manager. I tried to
reinstall in another PCI slot but XP only recognizes it as a "PCI device"
and the drivers won't automatically install. ...
If a transient damaged an NIC, well, an ethernet card must withstand
thousands of volts without damage. So what was the current flow
(circuit path) that flowed through that card (assuming the card is
damaged by a transient)? Maybe through PCI port, through NIC, down
cable, and through other ethernet port. What is and is not damaged?
Better computer manufacturers provide comprehensive hardware
diagnostics free and for this purpose. Answers obtained in minutes.
If no diagnostics, then get same, for free, from the NIC manufacturer
web site. Two possible damaged items: PCI port and NIC. Does the NIC
test OK when moved to another PCI port?
This manufacturer diagnostic eliminates numerous other complexities
such as Windows. What happens if the new card does not work? Is the
new card defective? Possible. Is the PCI port defective? Is
something in Windows causing a failure? Possibilities eliminated by
the diagnostic. Integrity of hardware on the other end of that cable
also known.

Unknown is if a problem is hardware or software - until simple
diagnostics provide results. Probably hardware. In but minutes,
useful answers obtained to identify all suspects. Rather than try
this, or try that, or try reloading drivers, or ... instead try
something that will report what is actually damaged.
Assumed was damage due to a transient. Maybe, which is why you may
also want to test, watch, or just automatically replace what is on the
other end of that cable.
One other reason for knowing what specifically failed? Also
eliminate that reason for damage. Thousand of volts to damage an NIC
via its cable. Where did something that significant come from?
Another item to fix.
