Macbook Pro Beachball, Freeze Fixed Solution

Last 3 days, I have been dealing with my Mid-2012 Macbook Pro to find out why suddenly stated feezing, and beachballing. "My macbook warranty expired."

What happened was when I wake up my Macbook Pro from sleep, it was frozen and couldnt do anything, so I push to power button feww times to reboot again. When the Macbook boot up, my macbook was freezing and beachballing when I click on any application, finder, safari, and it took long time to open them. It was almost impossible to use, everything was so slow. I was thinking this would be an issue with my hard drive which is a Sandisk 250GB SSD. i will write the steps that I did in order to help someone who had a problem like this.

1) I did PRAM, in order to find out if the problem with the system. (i did not work)

2) I open up the macbook, take the battery cable out and push the power button 10 seconds to reset everything (it did not work)

3) I went to disk utility using my bootable USB, and thought that this would be a marericks issue, erased, then freshed installed mavericks again, while I was installing it was taking so long and apple logo with scrooling wheel took also long but at the end, i was able to setup the OS, But no luck system act the same as before. (it did not work)

4) I though it would be a SSD issue since I bought it a year ago so I use some programs to check the heath of the SSD which appeared normal, no error. at disk utility I did a repair permission to the disk, everything worked fine, So I contact with Sandisk to get my SSD replaced since I could not find any solution.

5) I install my original hard drive 500gb, formatted and did a clean install, boom, it was acting normal no freezening no beachball until I wen to work and came back from home and awake my macbook, it started doing that again. I was thinking this hard drive also has something wrong after formating 5 times and reinistalling the mavericks again also I did the 1st and 2nd steps again. (it did not work)

6) I bought a new hard drive from bestbuy and asked them about the return policy because I just wanted to try with another hard drive to make sure hard drivers are ok and there is different problem. I bought a 320gb WD HD and formated and installed, at the beggining worked and a day later it become the same again. (it did not work)

7) i read lot of topics on problems like this and I found out this could be a hard drive cable or logic board problem, So I checked online and saw many topics and videos about hard drive cable symptoms and found out, people who had a empty file screen at start up. So I was having that very rare and my computer was working so I was thinking hard drive cable was fine. So in order to diagnose and make sure if its the cable problem. (it did not work)

I took my original macbook hard driver and put it in an external hard drive case and boot the computer from the usb so I would be able to see if it is the case since I took the hard drive out of the macbook pro and I took the hard drive cable too. I boot the computer and everyhitng just worked fine no freezen no, beachball anymore so I think the problem is the cable, I ordered new one from ebay and still waiting to come. I am %99 sure that it is the cable otherwise, my macbook wouldnt work with usb connected hard drive.

I know I wrote too long but I just wanted help other people to fix this problem if they had, I spent so many hours to find out so maybe this solution would help you to fix your macbook faster without spending too much time like me.

When I recieve the cable I will try and than let you know if it works or not but I am positive that it will work.
