Hi - thanks for trying to help! I've upgraded my Mac mini 2010 with SSD drive but now it is not turning on the display and after 2mins30s exactly I get a beep/tone that keeps repeating every 10 seconds without stop. I then tried to revert back to the previous non-SSD original hard drive and I get the same problem now I searched online and found nothing for this 10 seconds beep, any idea what problem I may have? I noticed that most common problems during SSD upgrade for this mini are: 1) damaging the thermal sensors on the motherboard 2) breaking the sensors that stick to the drive 3) or even breaking the motherboard when removing it .. but yet I can not relate to any of those issues. Since you may know better I also share some photos here: https://www.dropbox.com/sc/wpy817u0voe48rh/AAAkVUikxJ67nswjz3Ir09R5a Thanks again!
