As a first step in finding what the problem(s) may be, next time open ACTIVITY MONITOR set to 'All Processes'. This will show you all of the applications and processes that are being used by your MBP. Look for processes that are using high percentages of the CPU and for those that may be not responding. In the latter case, there will be a message to that effect in RED next to the Process name.

Ciao.

Ok, i found that there is a process named inkjet6 owned by _lp that is consuming 78-80% of cpu and taking 12 gb of v memory.

I disabled it for now. And i see a major improvment.

But what is this process responsable for and why it behaves like this - no idea..

Reboot the machine, if the problem appears again, then run through this list and see when the problem stops

With #8 it should be fixed as the stocked drivers will be replaced, but do the earlier steps as the cure might be easier than waiting to download OS X over hte internet.

Ok solved! It seems that a document was in the memory, wich was not printed by the HP printer in the morning. SOwhen i was at work, it generated problems. Once i attached my HP printer (back at home ) it started to print, and the proces was back at normal and dissapeared. Thanks Very much for the help. I own both of You a cool beer 🙂.
