You only have /var/log/messages from when the system started; who cares
about when it started when you want to know what happened before that?
Get the older logs.

It may also be useful to have the output of last | head -10.

Good luck.

About /var/log/messages… I did not pay close attention to the dates.
Unless your timestamps are WAY off nothing was in there from April or
March, so if that’s the latest you have then nothing is writing in
there. That’s odd since you should at least have stuff from the last
time you booted (presumably after February).

Good luck.
