Hi,

 

2005 iMac (PPC) on 10.5.8. When viewing a picture in Preview or iPhoto get this strange column-like hatching effect on screen. Also, occasionally the whole display freaks out and looks like a dog's (cat's?) regurgitated breakfast, until a restart which seems to right things for a while. Afraid the graphics card is heading south, can anyone confirm please? Is it fixable or am I looking at a hole in my wallet? Many thanks for any any advice :-)

 

Dave
