Everytime I turn it on I get a black box asking to shut down or restart the mac... I have managed to get it to turn on to powersave and managed to update the software... Thought it might help but just made it worse - it won't boot up at all now past an apple symbol with a little swirly thingy underneath (I apologise now for my lack of intelligence when it comes to computers/knowledge/names of things!) The first time I managed to boot the computer up it came up with the grey screen and a little folder flashing between a face and a question mark which I assume meant it couldn't find anything but that appears to have gone away now. I bought this computer new from Apple about 2 - 3 years ago and no disks were provided with it. Any help/suggestions would be very much apprieciated or even if it is completely broken just confirmation - I don't want to give up on it yet!!!
