Arghhhh replacement 3090FE is not working period. Really odd. In exact same system as before prior 3090FE sent back was working perfect (well except whine hence going back) this one VGA light on straight away.
Plugging HDMI into the motherboard which does have iGPU and taking GPU out, no issues, motherboard output is perfect. HDMI and DP issues no change. Just constant VGA light lit white. Used both included 12 pin adaptor and custom sleeved cable, no change. Third time lucky I hope
Tried different screens / cables / PSU's, nada. back we go!
Had a weird thing on the aorus master one I had where it literally wouldn't give signal to my lg cx after i moved my pc. Tried different cables and ports etc and no signal, thought the card had died. Then I pulled HDMI cable out of the card and put it back in, but not all the way in as far as it could go, and it worked, was really weird.
