You can access the MSI Web site and look at the image of the Mainboard by going
to MSI.com, click on the product, Click on the mainboard, click on the Socket 1155 and select the ZH77A-G43.
Even thought the MSI CPU support says that it will support the above mentions CPU with this Mother board, but i think the problem is the CPU. CPU is nicely fitted in its socket and fan is over it.
Any help is very much appreciated.
