I got this Xbox to check out and try to fix. A dog pee'd in the part of the case where the fan is. Only thing is that the Xbox wasn't on at the time. It was dried before being turned on. After it was turned on, it continues to just power off after a minute or two. I did open it up to try to clean out what residue I could see and tried again, but no luck. 

Any idea on what's wrong or what I could do to find the problem?
