Left DIMM slots not working
So I performed an upgrade to my 2010 iMac by upgrading its ram from 4gb to 16gb and also installing a second HD using the ifixit kit and instructions.
The install went smooth, but after powering back on the two left dimm slots on the Mac no longer work. I can populate both right slots , but any ram placed in the left slots (facing the front left side) doesn't work.
I'm assuming I didn't seat the logic board back correctly, or possibly bumped something else?
Any ideas would be appreciated. Technically I don't need the slots (just losing out on 4gb of ram) but I'm concerned something bigger is wrong.
Thinking of taking it back apart to straighten the board (back USB/network ports are slightly off but useable) and seeing if that does it.. Praying I didn't short anything
Is this a good question?
