I purchased a dual 1.25 powermac from compusa the other day. Ten minutes after I had it up and running, it just turned off completely. I set it up again, and the same thing happened. I took it back to compusa and they did not have any more 1.25's. So I just purchased the dual 1.42. This one did the same thing? So I thought my surge protector could not handle the juice of the mac and monitor, so I plugged it into the wall. Same thing happened again?!! What could cause this to happen? I am suspecting I have too many plugs going into this outlet, would that affect it? Thanks for your help!
