A year ago, I started having a problem where the display wasn't working; once to a few times out of the week the display would go out, and I'd restart the computer, and everything went back to normal. It started to get annoying, so I switched to integrated graphics via my CPU. A year later, I went to clean the inside of the desktop, and I tried to get the graphics card to work again. At first, the LED light on the graphics card turned on, but the fans weren't spinning, and I wasn't getting any display. I tried it in a brand new custom-built gaming desktop, and it was the same thing.
I then tried a different PCI slot and different power supply cables. I tried clearing the CMOS and reinserting the RAM. I had a spare GTX 760, so I tried that, and it worked. After I took out the GTX 760, I put the R9 390 back in the same slot as the GTX 760, and all of a sudden the fans on the graphics card started spinning. I was able to get a display after that, and I was able to run graphically demanding games on the highest settings with high fps and no problems.This is on a BENQ XL2411P monitor at 144hz. Somewhere between 30 and 60 minutes, the display goes away like it did a year ago. In conclusion, I have no idea as to how to diagnose/fix this, and/or if it's broken or not. I no longer use it, so I'm putting it up for sale for someone who's interested in it.
