I have the 15" PB w/ superdrive and everything.. the higest one before the intelmac came out. anyway, head it for a few months now and today, when i turned on the computer, it made a huge buzzing noise, almost like a horn.. then went to some dos looking page stating it was some Firmware thing. then I either have to type 'mac-boot' to continue or 'shutdown' to shutdown.. anyways so typed 'mac-boot'.. so everything loaded and seemed ok. Then once in a while, the 'shutdown/restart/cancel/sleep' window pops up that asks me if i would like to shut down my comp (the thing that pops up if u press the power button but this thing pops up outta nowhere... every 10 mins or so
any ideas?? thanks
