I have a HP DV6 laptop with ATI Radeon HD 6490M GPU. It came with Windows 7 preinstalled. I recently installed Windows 8 Pro onto it. The GPU(s) shown are Intel HD 3000 and ATI Radeon HD 7400 Series
How is this possible, Windows 8 detects a wrong GPU and installs the Driver also. The GPU shows a warning sign (error). I am not able to use the GPU, catalyst also doesn't recognize this GPU.
The GPU works perfect on Windows 7. I tried installing Win 7 drivers but it doesn't help much, the correct GPU is detected but it still doesn't work.
Any help is appreciated. Also I feel like no Windows 8 64bit Driver is available for this GPU.
