Hi All, I have a June 2010 17" 2.8 UBMP. It regularly has instances where by information on the screen regularly gets "garbled" &then freezes - it either just garbles the entire screen or a Column right down the screen. This garbled column then will appear across all other tabs, apps & even on the desktop. The only way to get rid of this garbling is either to close down the web browser which only sometimes works but more often a restart is required. Just for further information, this screen garbling also occurs for a few seconds when some web pages are loading. Can anyone tell me what is going on & if it is a software or hardware error? Is there something I can do (novice level) to fix this? Please refer to the pics attached! Bazzy!
