I'm really hoping someone can help me. Last week after attempting to run a software update on my MacBook, it completely froze. After attempting to restart, it wouldn't get past the blue screen. It would change from two different shades of blue but no logo or anything, just the changing shades. I tried PRAM and SMC reset, safe boot, hardware test, reboot from the install disk, I tried to repair and verify the disk as well as reinstalling to no avail. I finally took it in to future shop (only place I could take it in this small city) and got a new hard drive installed. Unfortunately I didn't have an external to back it up. Lost everything. All was well until this morning, I was trying to open an email when it froze again. Couldn't force quit or anything. So I tried to restart it again. Same thing as last week but a little different. This time I got the blue screen with the apple logo and swirling icon (?). I tried all of the above again. It wouldn't let me do a hardware test. I still couldn't Verify the disk. This time I tried restoring it from time machine ( learned my lesson there). After that the screen changed to blue with a folder with a question mark. I tried to completely reinstall, but it didn't give me a option to choose from. I don't know what else to do other than get another hard drive? Any advice would be greatly appreciated. It's a MacBook 13 inch aluminum LED backlit widescreen notebook, 2.0 intel core 2 duo.
