Displays GPU not detected

I finally got around in install some Corsair ML fans along with the extra dodads for flashy rainbow lights. No lights, played around with iQue and they came on when I turned iQue off. Turned it back on and they are working. All good.

I restart the computer to set up fan speed in the Bios. Hammer the Del key and black screen. Restart a bunch of times but no dice. Plug into the iGPU and restart. AMD software says it's buggered so into safe mode for DDU. Remove the AMD drivers and get an error when I try to reinstall them. The GPU is not even showing up in device manager and I can reinstall AMD drivers. Any idea?

 

Check you have the GPU seated properly and the power cables are plugged in all the way, first thing I would check.

 

It's worth a try. It's just odd that it happened when I tried to get into the BIOS.

 

I've had this a few time where reseating it fixed it.

 

I bumped the system while moving it around and it started working again.

 

My experience say gpu not detected is dead.
