Going to need some specifics... "Flaky" and "keyboard shortcut" don't quite do it.
i have a late model 2008 desktop mac 3,1 quad core intel xeon(3GHZ) 6 gigs of memory, i am completey up to date on my OS(10.6.3). i am trying to use the hardware test disc that came with the machine to check things out because the machine is doing alot of flaky little things. Upon trying to boot the disc i continuously get a message to resboot the computer by holding the power button for several seconds or pressing the restart button. there is no restart button, and holding the power button shuts the machine down. upon restart the same message appears. i tried twice more only to have the message appear. Also the keyboard shortcut doea not work, when i use that it just boots normally from my hard drive. Any insight would be appreciated. i am gonna re install Snow Leopard when i am on vacation at the end of June, when i can get whole day free to play with this. just wanted to check that the hardware was ok since the machine is under warranty
