I let someone handle my computer earlier, and now it's stopped working. It was raining while he was carrying it around. Having put two and two together, I'm willing to bet that something important got shorted out. The only question is, which part now needs replacing

I turned on the computer about 30 minutes after the case got rained on (stupid), and it abruptly turned itself off less than a minute after Windows loaded. Now, it's having a lot of trouble booting. Here's the full process:

0-10 seconds - Computer seems to boot up (disk drive lights up, hard drive spins, etc), but the monitor doesn't detect anything
10-15 seconds - Scary red lights flash on the graphics card, and the computer shuts itself off.
15 seconds - Computer turns itself back on. Same story, except it doesn't turn off again.

The computer turning off/on part suggests a power supply issue, but that doesn't explain the trouble with the monitor, so that alone probably isn't it. A shorted out graphics card would explain the monitor issues, but I don't see why it would cause the resets.

My own theory is that the power supply, or the connection between it and the graphics card, is somehow messed up, and that that prevents the graphics card from receiving enough power for the monitor to function, causing the computer to shut down automatically. Any comments or new ideas would be very helpful.

Try booting up without using the graphics card. Remove it and use the onboard graphics chip.

There is no onboard graphics chip, nothing else to plug the monitor into. Also, the computer seems to follow exactly the same reboot process whether or not the graphcs card is in.

Fun fact: there's still moisture where the graphics card plugs into the mobo. Given this, what part is more likely to be fubar, the mobo or the graphics card?

I'm letting the computer dry out for now, but I'm guessing that the damage has already been done. If things don't improve, I'll see what I can do about getting another graphics card to plug into the motherboard.

In the meantime, would a bad connection between the motherboard and the graphics card be responsible for the problems I've had so far? If so, which is more likely to be broken?

Hi, I would say it is your motherboard that is damaged, although it could possibly be both, If it does the same with the graphics card out then I would say motherboard. A cheap way to check if you have no other ideas is to buy a really cheap graphics card for maybe 10 and see if this makes a difference, If it does then its your motherboard :thumbsup:

Looks like the story has a happy ending. I left the motherboard and the graphics card apart overnight and let them dry, and everything seems to be working fine now.
