Seriously need help guys my life depends on this machine. What should I do? - tried reset PRAM, didn't help. - Sometimes changing the colour profile will do but it keeps happening everyday. - It only happens when there was a CD in the slot. - Almost every time happen after wake the screen up. - no matter the power line has been plugged or not this will happen.
