"no display", "no power on keyboard and mouse", "fans spin", "no beep"

I'm guessing: no POST (power on self test), I.e. "no beep", no flash screen, no access to BIOS setup.

You are correct to check all connections, etc. Did CMOS battery check out (3.2v)?

My first guess is that there is a screw floating around. My second is that your PSU is not giving a 'power good' signal.

Probe for floaters (I had a small piece of trimmed copper wire which held me up for several days). Double check connections (easy to be loose or 'off'). Borrow a known good PSU.
