I have a relatively old and decayed PC I'm trying to revive. Help me bring it to life? I'm at my wits end, and the motherboard may very well be fried.
Specs: ASUS M4A89GTD pro motherboard.

What do I need hooked up at a minimum to get the bios to boot? Currently it comes on, but no video signal is sent, not do my mouse or keyboard light up. I'm getting no sound codes or flashing lights.
