Why is my vehicle completely DEAD on 1999 Toyota 4Runner

My vehicle is completely dead/shutdown. My battery does have power. After turning off my car because of the squeaking noise and smoke coming from underneath, It just didn't turn back on.
Why?

Difficult to say without seeing your car, but sounds like a possible drive belt/alternator problem. If there was smoke, then have it towed in case there is a possible electrical short that can cause a fire.
