Second Monitor Not Working

I have two monitors, but only one is being detected by my PC. I used to have no issues with having two monitors work at the same time, but when I moved my PC a few months ago, it stopped detecting the second monitor. I now have a new second monitor, but the problem remains. The working monitor is HDMI, but the second HDMI port won't detect a monitor. If I switch the monitor connected to the first HDMI port, both monitors work, but not at the same time. I have also tried using a DVI port for the second monitor, but that doesn't work either. I am at my wit's end and don't know what to do to fix this issue.
