Question

Why do i need to restart my imac everyday like ten times to get it to work, also the screen displays little digital squares.

Answer 1

Hi Matt,
I purchased my imac in November of 2010 and below is a cut and past from Hardware overview. It has 1 TB hardrive, with 670 GB free. When i start up in the morning, it boots normal then freezes. Half the time i can get it to restart before it freezes, other half i have to power down then restart. At the same time throughout this process the little pixel squares show up sometimes in a single line or two aross the screen, then sometimes more random. After about 7 times of rebooting, everything runs fine for the day with no weird pixels. then i shut down at night, and start the porcess over in the morning. Thanks for your help!
