Hi everybody, So we are trying to install the latest OSX on a 2009 macbook. This morning my mom went through the installation process but when it came time to restart, she just got three bleeping tones over and over and a black screen. Well I read that this is a RAM issue so I took the memory cards out and put them back in again. This successfully restarted with the install screen coming up, saying '34 mins remaining,' but after a short time it said the install had failed and that there was a hard drive issue. boot up again, this time get flashing apple logo, question mark, folder and 'do not enter' sign So then I did a PRAM reset just to try something, that brought up the blue screen with grey loading bar, but it never completes, it tries twice and then shuts down. If I hold down option during start up, it brings me back to the three bleeping tones. Any suggestions, or is it time to take it in to the store?
