ATI Mobility Radeon HD 5470 drivers not working
I recently decided to reinstall Windows 7 on my Acer Aspire 4745G laptop with Switchable Graphics. After installing drivers with the Acer Resource DVD, I rebooted and thought everything was fine. But after checking Device Manager, I saw that my High-Performance GPU, which is ATI Mobility Radeon HD 5470, was reporting an error (Code 43). So now I am currently stuck with the Power-Saving GPU which is Intel(R) HD Graphics. Everytime I try to switch to the other GPU, I am greeted with a black screen. Any suggestions on how to fix this?
