i see that this model GA-H55M-USB3 has 2 revisions of motherboard

look at your MB and see what is painted Rev:1.00 or Rev:2.00

then go to MB site and check for updates bios, drivers

possible can be a setting in bios for onboard video

you lost onboard video when added a video card ?

read MB manual note: pic from Rev2
