You have seen water drops, so there's a clear indication of water damage. Unfortunately for everyone involved, water can do a lot of damage in places you won't even notice.
Because of this, there are simply too many possibilities for what could be wrong. With the possibility of water shorting out various components, there is also a real possibility that you will damage additional components if you try to swap them in.
If you are feeling particularly confident:
- Ensure everything is completely dry
- Ensure there is no visible damage to any of the components
- Swap major components (motherboard, hard-drive, CPU, memory, etc...) until issue is resolved
Without any real way to diagnose the issue (and the information you have given us is in no way enough for us to diagnose it for you), you are basically shooting in the dark at this point.
Due to the wide range of potential issues, and the aforementioned water damage, I would consider this a total loss.
Consider that you could replace it with a used, equivalent system from Ebay for < $100. At this point, it is simply not economical to spend more time than you already have to salvage this old, outdated system. That's not even including the potential cost of replacement parts.
