Doesn't boot, blue screen with patterns
After chime, apple logo and activity circle and it freezes in this state. or sometimes (maybe by pressed D button by startup) it changes the screen twice - clear blue to blue with small green patterns, with mouse in the left upper corner. I can move the mouse cursor but nothing more appears on the screen. sometimes the activity circle replace the cursor and I hear the HD working. I would like to fix the problem, any clues? Thanks
Это хороший вопрос?
I have a new situation. I can now startup in Safe mode, but if I try to startup in standard modus, it freezes as described before. I have also run the apple hardware test with no problem result.
