Hi. I have asus a320m-gaming mothboard. Recently my Hdd went bad so I bought a new one. Also I had gigabyte nvidea GeForce gt 710 installed. Now I removed that gpu. And plugged the cable to motherboard's hdmi slot via vga to hdmi converter in order to install win10. But when I started it I hear 1 long beep followed by 3 short beep. And my monitor shows no signal ie no cable connected. Even after hearing the 4 beeps the mb is on and running like fan and all. Need help since I am new in this area.
