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.
