I don't know anything about computers.  I did search the board -- no luck.
 
Can anyone help me?
 
Some pages are fine -- others are too wide -- on some I cannot (even)  'get to' the right hand side of the page at all.
 
Thanks.

What monitor do you have. What video card do you have? give us a little to work with.
 
Off hand I would say your resolution is off.  find out what the native resolution of your monitor is and set your desktop to be the same.
