if your monitor turns on but screen is dark:

* could be bad memory (does computer beep?)

* could be bad power supply (do you not hear any beep on boot)?

* could be bad monitor (does light turn on? do you see any led back lighting or if it's a CRT do you see a glow in the back? no glow, bad power supply likely)

* really stuck? make sure all your cards / the video card are inserted straight on and that they didn't get even slightly tilted when the holder screw went in. unplug your monitor. check and see no pins are bent or missing.

You really have to show specs and or photos. But time, time is nothing. A pc sitting for 2 decades should start up fine, minus some electrolitic capacitor problems in power supplies.
