Hallo..im bought from ebay faulty mobo and trying to find what is problem with motherboard.
Cpu is brand new i5 3570K.
The board powered up for half a second and then powered down, repeating the cycle every 5 seconds
The case fans do not spin up. The red CPU led light up during the half second until the baord shuts down.

So far i've tried:
-flashed latest bios ..didnt help.
-Resetting CMOS.
-Every single memory slot with both sticks,
-vhen Im press MemOk nothing happens.
-power supply is working because it stays on when I try it with a old MB.
-memory work ok..Im try on asus maximus v motherboard

Anyone have any clue what the problem might be?
