I’ve inadvertently damaged motherboards inserting RAM before now; sometimes it is really quite hard to push in and I have had a couple of instances where there was an ominous creaking sound, after which the machine wouldn’t boot.
Did your memory go in easily?
I may have missed it, I did quickly read through the thread though. What motherboard is it. Usually you can find a .pdf file on the internet that’ll show diagrams of the board itself.

My understanding is that you’re supposed to leave the power plugged in, use one of those wrist-attach ground strap devices to ground yourself to the power supply.
I never actually do this, and to date I’ve only blown up one PC, so maybe not. But I seem to recall hearing it that way…
I recently fried a CPU (I put the heat sink on wrong) and that machine behaved exactly as you describe. Power comes on, fans and drives spin up, but no beeps, no bios, nothing.
Off hand, I’m guessing you damaged something, most likely the motherboard.
