Please see the attached screenshot. The tiny squares keep shuffling around with windows and user activity. Their positions and numbers keeps on changing continuously.
Its an intel macbook core 2 duo 13 inch purchased in 2007.
I am not sure if this is a hardware or software problem.
When I connect the macbook to my 21 inch LG display, the problem happens on the LG display as well. So I am inclined to think its something to do with the display adaptor (?)
I have 2 RAM modules - one 512 MB (OEM) and one 2 GB (added later in 2008). I tried swapping their banks, and using only one of them at a time. No help.
I downloaded OnyX and verified the system with it. Its not showing any red flags.
I have downloaded and installed the latest software updates. That doesnt help either.
What else can/should I try, short of reinstalling the whole OS or taking it to the apple store
? Any pointers to diagnostic utlities/tricks greatly appreciated.
