You have either the recording volume settings or some
software related volume setting (if such exist)
set too low. Or you have a microphone which
is not compatible with your soundcard.

It might be new and working, but it is possible that it
is not compatible with the sound card you are using. 
Practically all the PC soundcards have 3.5 mm microphone
plug, but some soundcard are much more picky which m
microphones work with them correctly. Some information
on this microphone interconnection jungle can be found at

Usually the driver does not help this.
If all the microphone input hardware gain is used, then
no software can help this... Some soundcard have
an AGC (automatic gain control) option available on their
arecording settings for microphone and usually turning 
this on gives some extra gain for low level signals
(more volume for very low level sounds).
