Hi, I need some help here. I 've a 2 weeks old 17 powerbook 1.6 (no extra ram) and today i got a crash in photoshop. I had to force shut down and since then when i try to boot, the screen is black, the fans are going crazy, no start up chime. I've had the exact same thing with a G5 a few months ago (there was a thread here). Any suggestions ?
