I just had a recent update for catalyst control and driver but suddenly, my dedicated graphic card, Radeon HD 7750M, is not detectable on my laptop. Suddenly it was unable to be recognized by my laptop. So, my laptop is currently running Win10 with Intel HD 4000.
After some troubleshooting, I was able to find out that my laptop had labeled the AMD graphic card as a "Psi Bus" or "Psi Complex" whatever under system devices and not under graphic card with the intel card. I am really confused and I've sent days trying to regain control over my graphic card.
