Thanks, I ran the Onyx software and it certainly cleaned out a lot of of unnecessary stuff. However the problem still remains. So I ran diagnostics, CPU load is around 5%, 4 mb of ram used and 4 mb available. Ran a full virus scan, nothing found. Then I had a thought, I have a second profile that I created for my wife (but she never uses). Logged in with that and snap, everything runs fine. So I suspect that I have a corrupted user profile? So what now, can I repair it or what should I do? Thanks in advance  for your help with this

 

Do a search for Applejack

Its a command line utility that you use when you boot into single user mode [command-s]

Used it for years without any problems, can do checks on system and user prefs among other things.
