thank you for responding so quickly...
1>> i tried powering back on and it just went to the same white screen and then after a while an image of a file with a question mark in the center came onto the screen.
2>> i tried to turn it on in safe mode, but when i held down SHIFT nothing happened.
any other ideas? i'm just a little panicked because this is my boss' computer and he leaves for rome on sunday and absolutely has to have it. he is the host of Entertainment Tonight and his computer is used to record all of the voiceovers!
I tried to hold down the D key but still the screen remained white. The computer is new (last year), so it wouldn't be that the hardware test doesn't work.
There is no disk in it. Any more ideas?
still did the same thing with the white screen. i even tried that whole process with the safe mode start-up. did i ruin this computer?!
thank you so much for your help. unfortunately, that didn't work either. would i need to hold those keys down for over a minute?
what would the file folder with a question mark in it mean? after several minutes that shows up on the middle of the screen.
sincerely XXXXX XXXXX
I had our IT department at work take a look at it...they attempted to reboot using the leopard installation cd (I think) and said they thought the problem was internal--something to do with the hardware on the system. I'm going to take it to the genius bar at 2pm and see what they say about it.
Thank you for all your help!
