I am looking for some help on narrowing down the issue. I just got this MBA knowing that it wasnt working, but i was hoping it was a simple matter of needing to reinstall the OS. It will boot to the apple logo and the loading circle. It takes forever for it get paste the logo screen, but then it gets stuck at a blue screen with a black cursor. The cursor moves around like it should but nothing else seems to function. I have since put Mac OS 10.6 on a flash drive and attempted to reinstall the OS. From what I have found online its either the HDD gone bad or the logic board. So if any one knows what it might be I will be very grateful for the help.
