Greetings! I just "inherited" an Optiplex 7010 as my employer upgraded their computer and were going to throw it away. Coincidentally, I also have an AMD RX 240 that is low profile and fits the case perfectly so I gave it a shot.
When I boot up after installing the card, I get fan spin on the card but the monitor doesn't detect a connection. I just get a black screen.
Another forum post elsewhere recommending disabling Intel's built-in HD Graphics driver in device manager, then rebooting into safe mode. That didn't work either, same black screen.
Any suggestions? I have been using a DisplayPort-to-HDMI adapter so I'm going to try a new cable tomorrow to see if I have a bad adapter.
Edit: I'm using Windows 10 with an i5 3570
Edit 2: I meant to title this post R5 240, not RX
