acer aspire 4745g switchable graphics

I recently decided to reinstall Windows 7 (32-bit) on my Acer Aspire 4745G laptop with Switchable Graphics. Using the Acer Resource DVD, I installed drivers,including the ones for my display adapters (ATI Mobility Radeon HD 5470 and Intel Graphics Media Accelerator), and thought everything was fine. But after the reboot, I was stuck on the 'Starting Windows' screen. I waited a few seconds and heard the Windows startup sound, which means only my screen froze. Tried a few times later but was still stuck. I then went into safe mode and checked the installed drivers. Saw that the AMD 5470 wasn't using any resources because it has a problem.

For the meantime, I uninstalled the driver software for both as I don't know if I did anything wrong. Went to Device Manager and checked the display adapters again. ATI 5470 seems to be experiencing this Code 10 error (This device cannot start.), while the Intel seems to be working fine. Any ideas on how I can fix these problem and be able to use the discrete ATI card again?

Are there no guides out there on how to correctly install drivers for switchable graphics? Because I am still unable to use the ATI Mobility Radeon hd 5470, causing most of my games to suffer.
