Problem: computer wont start after water spill

Hey,
just after the water spill the laptop(dell inspiron 1501) the water had been wiped away,unplugged and flipped over. it was left there for almost 24 hours. when i plugged it in the battery symbol glowed. but when i pressed the power buttton there was the natural sound of a computer starting. the sound lasts about a second and then goes away leaving me with a blank screen. what could i do that without spending too much money.
