[QUOTE="shavian78, post: 1115582, member: 122137"] Hello forum, 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.
