My computer has a problem with beeping. I'll first tell you how it started:

One night I decided to watch a cartoon, and I took some water and food with me to eat while I watch. I fell asleep and when I woke up I had spilled water all over my keyboard. I didn't react quickly, because it went unnoticed for about 1 and a half hours. When I noticed, I quickly put my laptop on a radiator to try to dry it.

When I turned the computer on there was a constant beeping sound. I didn't know what caused it, and I'm still not sure, but I think it has something to do with the USB hub. If I let the computer stand for some hours without any USB connections, it's fine, but when I put any kind of USB device in, it starts beeping. The laptop keyboard doesn't work so I have to have some kind of USB device connected to use the computer.

The beeping is going on while I'm writing this and it makes my computer lag so much that it can make delays from the keyboard be from 1 second to 10 seconds. I need this computer because I don't have the money to buy a new one, and I have to use this computer for homework and games. The beeping is constant, with less than a second between beeps.

If anyone has a solution, please help.
