Upgraded RAM but 2017 iMac won’t boot up now
Mid-2017 iMac 27 with 8GB RAM. Was running fine right up until changing the RAM. I purchased 32 gb (2 x 16gb) from OWC.
I closed all apps and powered down. Disconnected the power cord. I carefully removed the old RAM and installed the new RAM. Made sure it was inserted correctly and firmly. I reinstalled the memory slot door, connected the power cord and tried to boot up. Nothing. Held the power button for 10 seconds (per Apple) but still nothing. I removed the new RAM and reinstalled the original RAM but still won’t boot up. Since there’s no power I don’t know what else I can do.
Appreciate any assistance. Thanks.
