imac intel will not shutdown

Hello

My imac intel has recently started to play up. Everytime I try to shutdown it gets stuck at teh blue screen with a spinning circle.

Has anyone else seen this.

latest apps that i have, but not running, is parallels. I also used Boot camp to partion my hard disk but did not install the os. so have a partion with nothing on it.

Thank you all for your help

Thanks. I meant that everytime I need to shut down it freezes at the blue screen with a spinning circle and then i have to hold down the power button for a few minutes or so.

Also my linksys modem router has started playing up. It looses connection to the internet and i have to power that on and off too.

how do i check what apps are running? ps -ef?????
I need to check what app is hogging my system up if any. Possible hogging CPU or memory.

Thanks

 

If I log off as opposed to shutdown all is well.

I think that when it is trying to shutdown some process is not being released.

Is their a log that gets generated when shutting down taht i could examine?

 

Can someone explain what is hogging up my system. Output below
