The mac hangs on blue screen and doesn't starts the systemsoftware
At startup the mac doesn't go true with its startup sequence and hangs on the blue screen.
The machine is still acessable as a external harddrive (at startup hold the letter T) but is slow and cant copy much at the same time.
- Multiple times cleaned PRAM didn't help
- HDD check was OK
- Hardware check didn't complete (hanged on the check)
- Did a clean instal of OSX 10.5 (original disc) no luck their either
What i didn't check yet is the RAM.
What can be the problem
