The MacBook Pro will just stuck on the Apple logo screen with the spining circle. Have tried the following:
1. Use Snow Leopard install disk to check and repair disk permission using Disk Utility. The DU said the disk is okay.
2. Insert the HDD on my other MacBook Pro. OS X boots. Therefore opt out the hard disk issue.
3. Tried to change the memory. Something all over again.
4. Use the HDD as external, install OS X Lion using other MacBook Pro. Will not boot on both machines.
5. Back to the OS X Snow Leopard. Boot from the installation disk, enter disk utility. Click the hard drive, chhose 1 partitom, using GUID Patton table. It tell me unable to partitin. Unable to unmount the volume.
6. Reboot. Changed other NEW hard drive. Same step, disk utility format the drive. Start the installation. The 3 minutes later, installation failed.
7. Pop in windows installation disk, tried to install windows. Failed format HDD again.
This is what I tried so far. I am suspecting the logic board failure. Since the failed MacBook Pro is the 2009 model, it is out of warranty. Will not want send to Apple to fix. So, if anybody will have any idea or any suggestions, please tell me. Thank u.
Typed entire thing on my new iPad.
