I'm having an issue with my GPU, yesterday when I fired up my PC, I randomly had no display. After a bit of troubleshooting, I discovered that if I lay my computer case on its side (so that the motherboard is parallel with the ground), everything functions normally, but if I stand the case upright, no display.
I believe it's the GPU because I removed the GPU and ran off of onboard graphics and had no issues, but as soon as I reinstalled the GPU, back to square one. I was thinking maybe the GPU is not properly seated into the mobo, but as far as I can tell everything looks good, and the GPU had been working fine for about 2 years up until yesterday.
Any ideas why this would happen? The GPU is a Saphire R9 270.
