Hello! First of all, thank you for this wonderful guide.
I had my GPU (ATI Radeon HD 4670 256 MB) repaired and I put it back following the instructions. It does work, but the problem is that I only can start my computer by using the Safe Mode. If I try to start it normally, I have a green screen, with the apple in the middle and a status bar that never ends. I contacted the guy who reballed the GPU, but he doesn't know how to fix it at all.
Has anybody had this problem? Does anybody know how to fix it?
Thanks a lot.
I have already recieved my GPU. I've installed it correctly, but it seems that there's a problem. It turns on, I hear the mac sound, I SEE the apple on white blackground, I see a state bar going bigger, but, when it achieves a 25% more or less, it shows a black screen with some coloured squares (some times) and then a whote screen. I hear the HDD and it seems that the Bluetooth keyboard works.
I have tried to reset the PRAM, I have removed and re-installed the ROM's 3V battery to reset it, but it doesn't change anything. What should I do?
