Chosen Solution
Hi, my computer is stuck on a grey screen with the apple logo and a spinning wheel. so, i bought a new hard drive, a hdd cable and os x snow leopard ( since i didnt have any os x) . but when i try to to open the osx i just hear 3 beeps interval and nothing happen. how can i solve this problem thank you. could other things cause that problem besides bad ram. because i tried one of the rams on my windows computer and it did work
The three beeps means your RAM is bad. First try reseating it. Next try just one stick at a time in one slot then the next so that you test both the slots and the RAM.
It is not the ram’s fault all the time… 3 beeps may also mean that you have a MBP that needs at least 10.6.7 SL to run the installation and begin the process!
Stop, do not pass go, use 10.6.8 or higher. 10.6.3 will not work on core i platforms.
2/10/17 I need to agree with pplantzos. I had a copy of Snow Leopard 10.6.3 install DVD in my DVD drive and instucted my iMac to boot from the DVD. This resulted continues three beeps and a five second pause/repeat, a gray screen, then a black screen with beeping. I removed all but one of the 4 ram sticks, and rebooted using the Option key to make it boot into Recovery. Interesting, installing any more than one stick of ram resulted in the three beeps and black screen with beeps.
You must install 10.6.8, or at least 10.6.6, as that is what was sold with the machine. Early 13 2011. I had the same issue with Early 15” 2011, but that was sold with 10.6.8. I would always get the ram beeps. But when I obtained an image of 10.6.8 it worked perfect. My copy of 10.6.6 would always beep
