Hello, I have a 15" Macbook and my friend dropped it from just about 1 feet height and it started to have problem on the display after about 2 weeks, then I went to the Mac city, they charged me about 3k to change the mother board, the problem was solved for the display. But now I am having a start up issue, it stopped at the Apple logo with loading bar, and it turns off after that. I am thinking if it was the hard drive because I stared the checking with Command +R and it sometime says that it's not able to be repaired, sometime it says appear to be OK. So and suggestions to fix this?
Just replace the HDD is confirm it's faulty. Only take < 1 hour to get it done.

I have Macbook pro Retina Mid and I am having sound cracking issues and the noise is getting worse day by day.
Any advice would be greatly appreciated.
If speakers crack there's no cure unless you replace them.
