Huge problem, please help

Last night, in my almighty clumsyness, as I was coming out of my bathroom the cup of water I was holding slipped out of my hand. The long side of my tower is parallel with my bathroom door and always has its side off. Needless to say, the water went nearly all into it.

I quickly unplugged the computer (I have no button that shuts it down immediatly), began swearing, and then proceeded to dry off the computer.

I took out every piece of hardware (all but my processor, I struggle to take it off the mobo so I rather just leave it there than break it), made sure it was dry, and looked for anything that seems suspicous. I couldn't see anything that would stand out.

Now when my computer starts up the power turns on, but nothing happens. No picture is received on the video, and the green lights on the keyboard never light up so I assume it's not loading windows or doing anything at all.

Now, onto my questions. Is it safe to use other parts from another computer to narrow down what might be the problem? If I took the power supply from this computer, and then hooked it to mine to see if the computer would work, would it fry the power supply? Or if I took mine to this computer and tested to see if it would work, could it hurt the computer?

I'm not sure exactly what the problem is. The computer is receiving signals from the RAM/CPU (if I unplug them it just beeps when I turn on -- that and the CPU fan still turns on). The power supply fan turns on. My hard drive got virtually no water on it. Will I most likely need a new power supply and motherboard?

Please help, my thanks in advance.

(If anyone happens to want to know, I have an MSI 645E max mobo, Pent 4 2.0ghz northwood, 128mb Radeon 9000 pro, and a 300w power supply. Not sure if this helps, but thought I'd post just incase)

 

i'd do a little washdown with isopropyl alcohol first, just to make sure some water isn't remaining. Now, instead of putting components in your box, i'd take your components OUT one at a time to another test machine, so you can see if A works, or maybe B doesn't. then you can replace the not-so-working components with new ones. good luck with this too.

 

sounds like the water caused a short circuit and has fryed some paths
