Actually I'm pretty sure my PC microphone is a crystal mic...
[The microphone that works is marked as "dynamic", whatever that means.]
I had a go with my dad's test meter. At 0 Hz, the working mic has a
resistence of about 600 Ω, whereas the non-working one is about 1.2 kΩ.
I don't know whether that has anything to do with anything. [I don't
have the specifications for my outboard sound card to hand...]
