TheseThis is a known issue with this series with the HD SATA cable. Apple has been replacing them for free. I would strongly recommend you visit an Apple Store or Authorized Service Center to have your system looked at.

I would wait until you get the HD SATA cable checked before doing these:
 
* Your HD may need repairs. Do you have an external bootable drive? If not do you have a friend who has a Mac system which you can connect your system to using a FireWire or Thunderbolt cable in Target Mode? If you do you should be able to run Disk Utility to check your drive.
* Often after upgrading the hard drive tend to get more fragmented. You'll want to free up as much space as you can. I strongly recommend you leave around 1/4 of the drive free before running a defragmentation program. To start off I recommend deleting out the Cache & Log files. Here's a tool that makes quick work off it: [https://itunes.apple.com/us/app/disk-doctor-clean-your-drive/id455970963?mt=12|Disk Doctor].
