Question

After using my browser (any of them) for a period of time I get a message saying that a page can't be opened. I have to reboot again. Clearing the cache doesn't help. It's very annoying. It even happened in the middle of a chat with Apple online support. I'd be very grateful for help!

Several things come to mind ... when you say your wife uses the same system with a different login and doesn't have issues, that suggests looking at your login items. Go to System Preferences (on your dock or on your hard drive in Applications), accounts, and on your account look at login items. Anything there that shouldn't be or isn't used? If you don't know, create a new account for yourself with no login items, and see if you still have the issue.
Next, I would run OnyX, which is a free disk maintenance program. You can download it from http://www.titanium.free.fr/download.php . Do the tasks on the cleaning and maintenance tabs. Before using any disk maintenance software, you should have a system backup. I periodically run it, and others have found that it can help with performance.
You might look at how you're system is using memory. You should have enough but it's easy to check. Bring up the Activity Monitor (on your hard drive in Applications/Utilities), and look at the system memory tab. Note page ins and page outs. If page outs are 10% to 15% more than page ins, you can use more memory for the programs you run. A page out occurs when memory is full and OS X has to write a section of memory to the hard drive. Too much of this can really impact performance. The optimal situation is for page outs to be zero.  Note these  values reset on a system boot.
