The first thing to do is to use a dmm to check all the voltages that you can.
I do not know you have a difference between vcore 1 and 2. The 3.3 volt and 12 volt lines are indicating much too low. We know those are erroneous indications, because the system wouldn't boot if those were real values.
The -12 volt line indicating way above tolerance is a common problem.
