Hi Bompy,
I had a similar problem but Apple telephone support provided an easy fix for me. 
Go through the process to restart your computer.   As soon as the screen goes black, depress the Option and the Apple buttons at the same as you press the "R" and the "P" buttons.  Hold all four buttons down during the restart. 
The screen will come on bright as if it is starting up like it regularly does.  Keep holding the four keys down and the screen will go black again and then after a few seconds, it will come on bright again and proceed to open as usual.  Let go of the four keys once the screen becomes bright again.  You have just cleared your cache and your computer will run faster. 
I usually then go into my finder and click on utilities.  Then I click on disk utility and work my way through to repair disk permission.  If you have different hard drives (like an external backup), you might have to click on the MAC HD icon and then hit the repair permissions button on the screen.  It will usually start out saying that it will take about 1 - 3 hours, but it usually only takes about 5 minutes or so.  Once it is finished, click out of everything and you should be good to go.
I have found that going through this process about every 3 - 4 weeks keeps my computer running really fast and it only takes about 10 minutes for everything.  You don't lose anything during the restart - it only clears cache items that slow the systems down.
I'm not expert and I may not be using the correct terms, but it does work for me everytime.
If you use the Internet extensively, you might also consider clearing cookies once or so a month.  Pull down the Safari icon and go to preferences and then go to privacy and the box will ask Remove All Website Data.  It will remove cookies and other tracking links that might slow down your system.  At the very least, it should help stop some of the endless emails that you'll get for products and sites from the sites you've visited.  The downside is that you might have to reengage some of the site you use regularly, such as banking sites, paypal, etc.  When you log on to them, they may say that you cannot proceed since you don't accept cookies.  Just type in the ID and password again (as usual) and it should open up like normal.
Good luck.
