My Powerbook G4 17 inch, after using it for 14 months. Now when I do flash or play call of duty 2 it suddenly goes to sleep mode and the screen goes black.
When I press the space bar several times it does not respond. I have to take out the battery and the charger then put the battery in again and start.
This had never happened before but now this week it have been doing it 4 times now. I dont think this is my fault. and my heart tells me the support wont do nothing they gonna tell me to pay.
Whats the problem anybody have the same problem? 
Thank you guys
