Problems with Console. Please help!!

Hi, I have tried searching for this problem but cannot identify a solution.
I am running OS X 10.5.8 on a MacBook Pro Late 2008.

Every time I go to launch ‘Console’, it loads the window but displays a spinning beach ball. Nothing happen and I end forcing the application to quit. I can not seem to find any large log files.

My understanding is that Console crashes when there is a large log? Could someone please help me locate the source of the problem?

My Mac knowledge is limited – i.e. I have never used terminal etc. Happy to do this, but please help with clear instructions.

Many thanks for taking time to read this!

I think I have found one issue: /private/var/log is 3.2gb!

Within that is a folder called 'asl' which has 3.2gb of logs. Before I even consider deleting, how can I identify the cause?

Many thanks!
