Got the R9 back from Dell, service summary says they replaced the fan and heatsink.   I'm not sure how that tied into no video signal or how installing a new SSD caused that, but maybe it was a coincidence? Anyway, everything works now and the cost to repair it wasn't bad. So       
Yesterday I added an additional SSD drive into one of the lower bays of my R9. I followed along with some youtube tutorials. Seemed simple enough. Don't know what happened but when I powered up the monitor just says no HDMI signal.  So I then removed the new SSD drive but the problem still persists. I looked up some troubleshooting ideas and tried 1. cleaning out any dust. 2. Pull out the RAM and switch the slots.  Didn't help.  Any ideas appreciated.
