@Nine @mavica one time I was switching to an SSD in a machine
I spent several minutes after removing the old hard drive and putting the case back together wondering why the motherboard wasn't seeing the new SSD
then I saw the SSD still in the box it came in
@troubleMoney @mavica heck I do this too. fuck, when I'm playing PC Building Simulator I do it too. and that's a game, and it straight up tells you you've not completed the case or there's missing parts.
Once built my system, forgot to plug the power into the graphics card, was baffled why the damn thing wasn't working, was all set to pull the card out and return it as faulty when I noticed the lack of power to it and felt really, really daft.
