Multi colored horizontal lines across the screen

Recently RMA replaced the motherboard.. with this motherboard, I am getting multi colored horizontal lines in my screen. any pointers? No graphics card is installed. Pentium G3220 + ASUS H81 Mv3

The problem related to the display problem from iGPU ( from the G3220 ), driver, cable, monitor. If you are sure the cpu, cable, driver, and monitor are fine, the MB has problem.
Also you use very low power consumption PC, so the PSU maybe not the problem, even I don't know what PSU you had.
