MB is a Gigabyte Z490 VISION G 4.8GHz Intel i7 10700 - 32GB RAM OS Win10 Pro - fresh install on a new SSD. MB is near new and Bios version dated a couple of months back.
New hardware is a graphics card Gigabyte Aorus Radeon RX570 4G
Bios setting for the MB a nightmare. Designed for gaming geeks who know all the acronyms and the instructions written for them. ;-)
I've disabled the onboard graphics and set to PCIex 1. Card says it is to the spec of that. The Bios sees something present in PCI 1, but doesn't say what it is. (I'd expect it to say what the card is - but the instructions not clear if it should)
The card does 'work' - I'm getting an output on DVI (which is why I bought the card). But only the screen resolutions of the default windows driver it's using - and pretty useless.
Win10 did find something and auto loaded a driver called Raydeon RX570, but that has a Code43 error in Device Manager. Tried updating the driver, obviously. Installed the entire software suite for the card, and that said installing drivers, etc. But when attempting to run that software, it says card not found.
I bought this card described as new off Ebay. But it arrived with no makers box, software or instructions. Not even in an anti-static bag, just loads of bubble wrap.
I'm hoping it is finger trouble this end.
