• 2011 21 inch iMac won't start after the SSD upgrade

  Recently, I upgraded my hard drive for an SSD via a computer repair business in my neighborhood, I also upgraded the ram, but I don't think it's in the case. On a two weeks after the upgrade, my computer don't turn on more. I took it to the genius bar and they told me that the DSS had "failed." So of course, I took my computer to the computer repair company and they ran some tests, discovered that the hard disk does not (according to them, he only read this way because the apple store has run the test for a normal hard drive and not an SSD). I'm not super computer savvy, so I took their word for it.

  Now, however, it has been nearly a month and my computer refuses to activate once again. Previously, it has worked well, the fans were running at full blast - what I knew would be a problem (although the repairman told me that they 'fixed' this issue too). So the first time, I downloaded a program called SSD fan control and set the fans to run in silent mode. This second time around, I realized that it was probably a bad idea because it could lead to overheating, so I put manually the fan speed so that we could hear still run, but just not as loud.

  I tried the reset SMC, but no result. Right now, I unplugged everything including disconnect it from the power strip.

  Any other experience of power with a new SSD failure? Is there anything else I could try at home before contacting the computer again repair business? I would not be able to reach at least until tomorrow, and I'm really curious to know how they managed to get my computer back on the first time.

  Also, I've been out of my warranty period for about a year, so that's why I thought that I was not risking too much by exchanging the original for one SSD drive.

  First of all, the original in Middle 2011 iMac hard drive had a temperature sensor integrated in the drive.  More new or replacement of those who do not.

  Other World Computing sells an Apple certified temperature sensor that plugs into the SATA cable.

  https://eShop.MacSales.com/item/OWC/DIDIMACHDD11/

  I just put a 2 GB Western Digital Black in mine, with the sensor.

  I suggest all first, reinstall the OEM disc and see if it boots.

  Put the SSD in an external enclosure and see if it runs...
