I was playing games a while ago, After I shut down my computer then turn it back on in 10 minutes. My monitor got stuck in no signal without the boot menu showing up after I reboot my computer 3 times. So I know is my VGA connector is the one causing the problem, I bought a new one. After I replaced them, my monitor still stuck in no signal. I noticed that there's an another VGA port so I tried plugged in and my monitor got fixed and my games are not working anymore.
Here's is my question.
1. Why there's a 2 VGA port
2. Are there any ways to fix the broken VGA port
3. Why I can't play games anymore after I fixed it
Thanks.
