I let my brother use my laptop computer for quite some time. He returned it and now I have a problem. It wont start up. I turn it on and It loads a Grey screen with a folder in the center of the screen. On the folder there is an Icon the flickers from iMac Logo to a Question Mark. I dont have the old version of Mac OS9, which is on the computer. I went and got Mac OSX Panther and tried putting it on the computer but it wont load the CD. If I push the Option/alt key on the keyboard.....2 arrows appear and the background turns blue. The Flickering folder still remains. One arrow is a circle arrow and it kind of represents the "refresh" key used for Internet explorer. And the other key is a simple arrow pointing to the right. When I put the CD in with this screen up the CD appears in the middle almost the same spot where the Flickering folder sits. I used the two arrows but the CD still wouldnt run. The computer just loads a little and then simply quits loading. Also the computer turns off in about 10 minutes if I leave it unattended when I start it up. I have tried starting it up without the Battery and with there is no difference. My brother said he dont know why this happen. It just didnt work one day. Finally to my question. Is there a way to load a boot screen on the start up and erase the HD? Im an Amateur PC user i'm sure iMac arent too much different. I can't tell you anything about the laptop other then it is a iBook M2453.
