blue Lines rectangle following cursor and all Applications and system freeze - snow leopard
hello,
i have a big problem with my macbook pro
when snow leopard 10.6.8 startup, gray screen appers and freezes.
what did i :
1 - i tried to boot from Install DVD but blue screen appears and freezes.
2- i booted from external HD in safe mode and i erased my HD by disk utility and i installed clean os from external HD ( in safe mode - blue lines around the cursor - see the picture)
but the problem still,
i booted in safe mode and i updated the os to 10.6.8, and the problem still,
3- i reset the SMC and PRAM and EFI. and same problem
4- i repaired the disk and permission from ( external HD - safe mode and from single user) , after that the system worked fine and no problems occurred,
i startup snow leopard normally and every thing fine, but i tried to open any application - blue Lines rectangle following cursor and all Application freezes, but i can move the mouse.
the problem sometimes happens and sometimes not.
i opened disk utility and verified disk, the hard disk is ok
i repaired the disk permission - the disk utility repaired many files successfully (every time i repair the disk permission, same files repaired but not working )
- i changed my RAM and HD - no results
i tried to install lion os but my mac dual core, lion os mini Req. core 2 .
- any help please?
