No signal with 7870 unless another card is installed with it
I seem to be running into a very strange issue. I recently cleaned out my computer, updated bios, reset cmos, and now my gigabyte 7870 won't display by itself. I had previously been using it fine for the last three-four months. If I install a 4890 alongside it(not plugged into power nor into monitors, just seated) I will get video output from the 7870. Otherwise if I run the 7870 alone, I get nothing, but I do hear the windows login sounds etc.
I've checked my bios and it looks correct. I have legacy enabled as well. Has there been any other sightings of something like this?
