It powers on, and then shows a picture of a folder with a question mark on it.
I tried reinstalling the OS X, but the Leopard installer doesn't detect the HDD so it cannot be erased and installed onto.
Disk Utility in the installer does not mentioned the HDD.
When I go to System Profiler, under Serial-ATA it says "error detecting serial-ATA devices" or something similar.
Any suggestions? If it needs a repair then so be it but I'm lead to believe that logic boards are not cost-effective to replace, so I'd like some way to try to work out if it is the logic board or HDD playing up before paying for an inspection to find that a repair will not be cost effective
