Hi there, Im new here so dont take the pee if somthing is wrong lol. here goes, Its long mind. Basicly I had my mac in my room working fine no problems. I had to move it downstairs because my friend was borrowing my windows. Basicly I cant boot my mac. When I press the power button it turns on, makes the tone and thats it. The monitor doesnt turn on, stays o standby, thats all it does. The only way around it is to take the battery out and press the small reset button on the motherboard. That is the only way I can turn my mac on. I have reset all the PRAM etc etc, but nothing seems to work. I cant see what the problem is. Ive never had this problem before, ive had 3 different monitors on this mac and its been fine. I have tried the monitor on other computers and it works fine, so i dont think the monitor is damaged. But like I said every time i want to use my mac I have to open it up, take the battery out press the button THEN i can use it! I am pulling my hair out with this. I done a fresh install of OS X to make sure OS X wasnt the problem and i still get the same problem. Just its fine if I keep my computer on 24/7 but I dont want to , mainly because its in the same room as my dogs, the fans will drive them nuts. I bought a new graphics card a while back which was fine. but when i got the problem i out the original back in and nothing. check all the RAM and nothing. So i am completely stuck now! I would be very very grateful if anyone could help me. I have made no modifications to it, just the new graphics card thats all. This is the mac I have, G4 AGP..well another question, when I installed OS X it said it was a AGP model, but I downloaded the user manuals from apple website, and from looking at the manuals and matching everything I seem to have the Gigabyte ethernet model. This is really confusing for me. I want to get upgrades but I dont have a clue what model it is. AGP or Gigabyte ethernet. Thanks again! James.
