So we tripped the breaker last night, an my girls mac pro (2008/2009 i think) came up with blinking ? folder, ok so i figured system drive died no biggie. This is where the dilemma starts. I cannot boot into AHT (completely ignores my command and proceeds to throw the question mark). Holding option to get to start up manager just shows the cursor on white/gray screen. Holding C to boot from osx dvd just waits there ejects the disk and throws teh question mark. Trying to get into Open Firmware does the same. the mac originally came with 10.5 and is running 10.5.8 now (or was) What the hell is going on?
