The hard drive powers up but will stop spining after awhile (around a minute), the Welcome starting up screen is as far has It goes.
If you have to ask about checking Amps (current), you don't know enough to know how to do it without probably damaging something.
I say that as someone who years ago before I actually got formal training in electronics didn't really understand current measurements and managed to damage some stuff.
If the only wire colors going to the motherboard from the power supply are yellow and black, and you're getting a steady reading right around +12V, then the power supply is almost certainly okay.
Does the cable that plugs into the back of the hard drive go to the motherboard and only the motherboard?
If so, then there must be something on the motherboard that provides +5 V to the drive as well as +12 V, and there could be a problem with that, but I'd pull the drive, hook it to a PC and boot with a cd with the drive maker's own diagnostic software on it and run their tests before I started messing with the motherboard.
