So 2 weeks back I got a new build which included CF of R9 270x. Upon installation everything worked fine, no issues. Lately my temps were a bit on the high side so I decided to switch around the GPU's yet now my crossfire isn't being detected. Switched back, still nothing. Reinstalled drivers 5 times, nothing. Tried both GPU's in pci slot 1, worked perfectly. Tried both GPU's in pci slot 3, no display with either one. Faulty slot? Suggestions? RMA :(? It litteraly worked fine a few hours ago...

R9 270x CF
i7 4790k (not OC'd)
Corsair RM 750
MSI Z97 Mpower
Kingston Hyperx Blue 8GB
CM HAF 912 Plus
CM 212 Evo

Forgot to mention that when I took out the GPU from slot 3 I forgot about the slot lock and just kind of 'ripped out' the card, the lock came off but it's just an easy mechanism which I could fit right back into the lane.
