Dual monitor not working - AMD Radeon R7

Hello, I have tried to hook  up my second monitor. When I hook it up(I am using just a simple VGA cord for my main monitor, My second monitor is hooked up using a VGA cord and an VGA to HDMI adapter, because my graphics card only has a VGA port and an HDMI)it just says no signal. When I go to my display options it registers two monitors, but my second monitor won't register the VGA input. I know the monitor isn't at fault because I plugged the cord from my working monitor into it, and it displays just fine. So Please Help, and Thanks in advance!
