Can't connect after restart

Hi,

We've been having trouble with a pgSQL 8.0.3 install
on a WXP machine. Install goes fine, DB works until we
restart the machine, then we can't connect. First time
we thought something was corrupted because we had a
power outage, we uninstalled/reinstalled and it was
fine until, again, we decided to reboot. We were
thinking it was a problem with permissions, but it
doesn't make much sense to me that it's working fine
before we restart.

So, what can I send you to better describe my problem?
Do you think it could be a problem with permissions?
How can I test to find out what the problem might be?

Thank you.
