looks like i am facing the same issues as you. When i installed the first software you gave me tinstall and tinstallwb would not load just the waiting cursorer came up and went away, so i went through setup.exe and i guess that just did software not drivers.
So i went to the support page like...
I uninstalled the driver, rebooted and installed the driver you posted. hasn't crashed yet but i noticed when i went to device manager i look under display adapters and i now see: Microsoft Basic Display Adapter
Hello everyone, Windows 8.1 laptop and i get BSOD for atikmdag.sys. The other issue is when i use the tool that you provided it does everything but when it comes to the zip file nothing is in it. Yes i am giving it admin rights.
