Hi, I added a new ssd in my pc and plugged it in sata port 2. I learned after that that the pc boots drives one by one starting by sata port 1. And so by computer was not starting. So i changed my boot drive to port 2 and plugged my new drive to port 3. Now my pc is starting but my monitor detects no signal. I tried with the onboard graphics and same thing. Everything is working, the graphics card, all the fans etc but I get no signal. I tried resetting the cmos by shorting the 2 clrtc pins but it changed nothing. I want to try with the header but I cant find it. I'm using an Asus Prime B360-A.
