hi
8 months ago, my imac suddenly started to crash, the screen became black with vertical lines, the color of the lines and screen changed everytime, i checked the internet,apple hardware test said that my logic board and etc are working fine, after that i reset the nv/pram and smc,installed graphic firmware v.20, format the hdd and installed the mac os and windows again, but the problem didn't solve
there's no applecare in my country, so i gave it to some local warrenty in my country, he said there's nothing wrong with logic board, i just needed a small service
after 8 months, i'm facing the screen with vertical lines again, its usually happens during the game.
what's the problem?
iMac Mid 2011 27"
Intel Core i5 3.10GHz
4GB Ram
6970M 1GB VGA
1TB Seagate (checked it on apple hard replace, it was ok, doesnt need replace)
Mac OS 10.7.0
Windows 7 SP1 (Bootcamp)
