Stuck on startup after software update.
Well let me start by saying im a novist do it youself computer guy. So here's my problem my macbook was running flawlessy since i bought it in late 2009. I recently performed a normal software update and was plugged into power supply. It looked like it was going smoothly up until the restart, it never came on and stayed stuck on the gray apple logo. The cursor was in a shape of box about the size of the gray apple on the screen. I waited and waited and nothing. I researched this on the web and found that I could have had corrupted files in my HDD so I went out and got a new one. Installed it and partioned it and got it working, at last my macbook was fixed! But after loading the OS I went and did the same thing again and updated the software and it happend all OVER AGAIN. At this point im very frustrated and lost. After talking to an "expert" he thinks cpu chip is bad otherwise known as the processor. Please any input would be greatly appreciated I just would like to know if anyone has experienced this and has a solution for this annoyance! Thanks in advance.
Is this a good question?
