So I was watering my plants which sit on the windowsill overlooking my desk which is above my tower and after the water drained into the dish, it overflowed, dripped onto my desk, trickled towards the edge and made it's way onto the top of my case. Some water got in and the computer, which was on shut off and won't start up or seem to get any power whatsoever.
When I opened it up, I couldn't see exactly where the water had dripped. I don't think it got on the power supply or the graphics card as they both have an undisturbed layer of dust. I also pulled the leads to the case power button and tried to short the on switch but still got nothing.
If I were to guess the damage is to the motherboard.
1. Is there a way to test the power supply to rule it out, assuming the motherboard is non-functional?
2. If you dumped a bunch of water onto a motherboard while a computer is running and nothing else got wet, (how) would the other components be affected, if at all.
3. Other likely parts I should consider before just buying another motherboard?
