Postgres service won't start, doesn't log any errors

Hello all,
I have a windows postgres 9.0.1 installation which doesn't start, and also
doesn't log any information. The only evidence that an attempt was made is
in the event log with the following pair of messages :

1. Waiting for server startup...
2. Timed out waiting for server startup

I've tried to run postgres.exe from the command line to glean more
information, but it starts and stops without any output as well. I have
uninstalled the server, moved the previous data directory, and reinstalled
to no avail as well.

I'm wondering what debugging steps I might be able to take now to track down
the source of the problem? Thanks beforehand for any assistance.
