Since the Intel Core i5-760 does not come with "Integrated Graphics", you must insert a PCI-E VGA card on the H57H-M/V1.0A MB with this CPU to get the display.
For more information about this behavior, please check out the Intel website below.

Besides, if you have only one pc of memory module, please install it into the DIMM slot of DDR3_2 or DDR3_4 as our menu mentioned on page 12 below. Otherwise, the system won't boot when you insert the RAM into DDR3_1 or DDR3_3.



 

According to the datasheet of Intel 5 series chipset, Intel graphics cannot be used along with an external PCI Express graphics controller. Installing a PCI Express graphics controller will disable Intel graphics. Please refer to the following website for more information about Multiple Display.
