Computer would not restart after RAM upgrade

I attempted to do this upgrade on my own, and after seven painstaking hours, the computer would not turn on after the upgrade. I took my computer to a local authorized service agent, and they have quoted me a price of $600 if the logic board was somehow damaged during the upgrade. Has anyone else had this happen while attempting to upgrade the RAM on the 2017 iMac? How likely is it that I somehow damaged the logic board during the upgrade? I was very careful when I removed it and when I replaced it, and did not force any parts to fit, etc. I’m absolutely terrified that my computer won’t turn on, and angry that I trusted that the “moderate difficulty” rating of this task when it was far, far more difficult than that.

Hi

It’s possible, but unlikely for the logic board to be damaged. Logic boards and memory modules are electrostatic sensitive devices. Touching them can potentially create small electrostatic discharges that would damage them.

Most likely:

  1. the new memory modules are not compatible or faulty. usually the system will beep when you try to power it on and there is a memory issue. But not always. I myself have a laptop which had a faulty memory module and simply refused to turn on. No beep, no nothing. Replaced the module and all was fine.
  2. some of the connectors are not properly seated. Because the entire logic board needs to be removed in order to access the RAM slots, there are multiple connectors which need to be disconnected and then connected back.

I would try the following:

  1. open the iMac again and carefully check that all connectors are plugged back correctly.
  2. if this does not work, put in the old memory modules and check

Good luck!

Bogdan

It turns out the logic board was in fact damaged during the upgrade, and now I have to try to buy a brand new computer, because the cost of the labour + the logic board is very close to the cost of a new iMac.
