Hi,

Try Disk Utility to repair permissions first, then reboot and see what happens.

Thanks for the reply...

I did this but.... nothing, keep having problems.
I tried this in the root account, but no results.

Hi,

OK have you tried resetting the SCM and PRAM? As this can fix a plethora of issues.

I would just add I’d do a TM backup then disconnect all drives, speakers, external displays and keyboards before you try this stuff, well thats what I have done on the odd occasion I had to over the years.

If you have never done this here are the links
