So, i recently bought a R9 270 second hand (starting off strong) which was at a reasonable price. It was for the "eGpu" experiment,which we have successfully tested with other GPUs such as (GT8500) and everything seemed to be working fine. However, when we got the card we were barely making it to the desktop screen. The GPU showed as "Standard VGA adapter" but seemed to heat up, and, as always, spin the fan. When we tried installing the drivers it actually recognised the card and we proceeded to the installation. But at the end we received an error, which mentioned "The drivers are not installed". Every other time we tried to boot up windows.. blank screen, only showing that there is signal coming from the input itself. I'd be glad if we find a solution to this endless trial and error.
