Error 173 and AMD Radeon 570 problem

[mbii]

Hi all
Thought I was doing the smart thing buying a cheap card to fill in the gap till all the new ones are out. Unfortunately I picked one that comes with it's own brand of hell. The card is fitted and powered up but keeps getting this "Error 173 your card cannot be found" message, it doesn't show up in device manager.
So far I've tried the last three sets of drivers, moving to a different PCIe slot, taking out the wireless card and using DDU to wipe the previous. All to no avail.
Would really appreciate any help as I'm at a loss now. Thanks

It's on an Asus Prime 370-A motherboard

sounds like the bios needs reinstalling though how you could do it without the card being recognised is a problem
