Although your grammar is difficult to understand, I believe you are saying:
-You unlocked your other two cores.
-windows would not boot.
-You successfully unlocked the fourth core of your previous phenom IIx3 720.
-It doesn't work.
correct me if I missed anything or misinterpreted anything.


Answer:
reset your bios to undo the unlock. either by doing it in the bios menu, or by clearing the cmos.

AMD makes phenom II quad cores. If one core on it is defective, they will disable it and sell it as a tri-core. If two of the four cores are defective, they disable two cores and sell it as a dual core. In your case, windows will not boot because those other two cores are defective. You unlocked your phenom IIx3 720 because you got lucky. If AMD has more demand for a tri- or dual core, they may take a perfectly good quad core and disable one core. This is why unlocking will not always work.

Not all Phenom X2's or X3's will unlock and work correctly.
If you buy one, it unlocks and works, you are lucky.
If you buy one, it unlocks, and does not work, well then you simply got what you paid for.
