case creating a short

So my case is creating a short somewhere on my motherboard so that it won't power on. I decuded this by the fact that it will not boot up when its in the case, but starts up just fine when its outside the case.

Question 1: How would I isolate where the short is?

Question 2: How would I fix it?

Nevermind this thread I have delt with my problem

so what was the problem and how did you solve it?
