I foolishly left my PC in my apartment when I evacuated from the hurricane. We did not flood, but a window in the room next to mine busted and it was very humid following the storm with no A/C. Now my PC will boot only sometimes. When it doesn't, the motherboard gets stuck on code "C1" (base memory detect) and have a two-second beep with a three-second pause between beeps. Does anyone know what this means?

I want to try to avoid wiping down the board unless I absolutely have to. Thanks for any help!
