Comparatively little solder is used in modern PCs. Even the solder will not necessarily contain Silver.

There is definitely some Silver somewhere in BGA chips, because I often get some Silver Chloride while processing them, but it is a tiny amount and Silver has a very low value.

There is also Silver in Crystals, Crystal Oscillators and keyboard Mylars.

If you want to target Silver you are probably better to look inside switches, relays and circuit breakers. Silver is used in the contacts inside these because of it's great conductivity.
