Right, well i don't know really anything to macs because i am new to them. But i have this old mac(Power Macintosh 7200/120 is all i know of it) and the problem is when i go to boot it up, it loads up all the extensions but once it gets to the last one or whatever number it is, the entire system reboots itself, and this continues in a loop until i just shut it off. I have no idea what is wrong with(other than it is probably too old and went bye bye). i can get past the smilie face and all that, but once those extensions load at the bottom and it hits this one it just reboots. I have tried looking at it but it reboots before it shows the icon. this is also very annoying because the internal sound is on x.X;; Can anyone please help?
