[Pc_Support] Smmmmearing on several applications

[Homer Whittaker]

Apparently I am loosing one of my cards or the mother board.  
While using several different browsers, Firefox and also Mozilla 
the page I am working with starts to smear and seems to have 
numerous background verbage, pictures, and just straight 
smearing.  The latest time was when I was writing a letter in 
OpenOffice and it smeared on me to the point that I could not 
finish (lost) the letter I was writing.

Any thoughts as to what it might be?
