okay i will try finding my volt meter it is some were around the house.
no chip on the xbox i just did it all through hotswaping.
UPDATE:Okay i think i found the problem there is corrosion on the back side of the board. in between the 7 and 6 there is bad corrosion on traces b and c and maybe d.
So i have classes tomorrow but i might run by radio shack to get some kynar and follow this tut i found.

UPDATE 2:I didnt go to radio shack i had the wire at home so that saved me money and a trip.
I wired up all 4 traces up and to tell you the truth the stupid via's were the biggest pain in the butt they would not take the solder.
So i layed the wires over the via and taped them place then soldered the two resistors up and then pluged in the unit.
it did not turn on by itself problem one fixed next i pushed the power button and the unit powered up and to my surprise the dvd drive did not open and clses it stayed shut problem two fixed.
new problem
problem 3
but once the main boot screen finished the xbox shut down i figure i had a short so i disconnected one wire at a time until i only had the B one connected to a resistor to via point and the until boots up fine and is working like a champ.
I only told what i did and experienced to help other who are having the same problem it may not be your dvd drive but corrosion on the board. Do not solder if you cannot hold a stedy had or do not have flux.
well next is to work on the case modding now i have all the trouble shooting done.
