Liquid on PC/laptop is not something to be taken and handled lightly.
If you have something like that, you shall try to turn it off completely and disconnect it from any kinds of power e.g. battery, electrical plug, etc.
Before you even try to reactivate it, make sure you clean it thoroughly and let it dry completely.
Any substance residue, may it be water, soda, sugar, etc., will damage your PC and it will cause damage faster, if you turn it on.
Reading your description,
It is possible that your PC might have already been damage already but cleaning thoroughly again and drying correctly still worth a shot even now, perhaps you can still prevent the worse damage.
Look into those RAM slots, GPU slots, etc.
