A2 error msiz270

[george_178]

Hi
I have installed a new PC with an MSI z270 .I7 7700k .gtx1070 and when I wanted to start it the motherboard showed an error code A2 and on the screen this following message:
Over current have been detected on your USB device !! System will shutdown after 15 seconds to protect your main board.
I tried to unplug my HDD .ND I changed the ram location .No luck
Please could some one help me solve this issue
Thanks

Hi,
A2 indicates that the system could not find a bootable device and it is not related, in my opinion. to the over current message. Try disconnecting from the board all wires/cables/USB devices not needed for starting the pc and see if same error occurring.
