    I recently recieved two old macintosh powerpc's. one is ok but the other is a tower version with transplanted harddrive and cdrom drives. I log on to the computer and everything is perfect for about ten to twenty minutes :D and then it freezes and only responds if you push force restart (apple + Control + Power). on restarting it makes the mac power on noise but i get no picture!!! :confused:
    If i turn it off at the wall for an hour it is allright but i would prefer not to have to do that, please help me!!!!?? :(
    Post a reply or send me my answer at My Email.
    I'm thinking of pulling it apart and cleaning it to get rid of any dust build up. if this or any other situatuion has happened to you, please answer as i am desperate!! :eek:

    First thing I would try is replace the battery, on the motherboard.
    You can try zapping the pram too.
    Good luck!

    Yeah, I would reckon the battery.

    Could also be power supply problem (especially if Hardware inside has been replaced) cos there might be compatibility issues. Could be overheating problem.
