Strip it down to absolutely nothing (Motherboard, CPU, RAM, PSU,
CPU fan) and see if that much works. Possibly wire a speaker in to the
speaker header on the motherboard and see if you get a beep. If that
works, add parts one at a time (turning it off while you do so, of
course) until it stops working.

If there's no signs of life even in a minimal configuration, take
the heatsink off, clean it and the CPU, and re-apply the thermal
compound. Also try another PSU, and that PSU with another machine.
