shorts can be fixed most problems are is people put the mb in the wrong type case or touch it with hands with out touching the case at the same time take the mb out and look and see the case is touching the mb some whare also make sure you have the right power supply wats like 180 to 300 are common for newer mb and if you have volt meter test the power supply to make sure it working and make shore the mb caps on the mb is not blown ty paul post back if you need more info

Your motherboard controller chip is not working,so replace your motherboard instead of CPU,RAM and Hard.

You may want to try a little punctuation as your post makes no sense at all.
Also, use complete English words as per the site rules.
