Getting BSOD while windows sturtup
Problem caused by a file atikmdag.sys (0x0000003B error number)
Evidently problem caused by switchable driver because with switched off one of graphic adapters windows could start.. same with standart VGA driver.
on Windows 7:
Fully reinstalled Visual C++ Redistributable and NetFramework
1. a) ALL AMD drivers deleted with DDU utility (in Safe Mode)
b) Installed Crimson Edition 16.2.1 Beta
2. a) ALL AMD drivers deleted with DDU utility (in Safe Mode)
b) Installed switchable drivers from HP website HP Software and Driver Downloads (dv6-6c33er)
3. a) ALL AMD drivers deleted with DDU utility (in Safe Mode)
b) Autoinstalled Microsoft drivers
on Windows 8 were done all points such as Windows 7 (BSOD on each)
on clean Windows 10:
Autoinstalled Microsoft drivers (all other variants is not suitable here as I understood by reading the forums)
Q: Why you couldn`t disable integrated graphics?
A: There are no Fixed mod in BIOS sittings and there are no any other BIOS firmware with this option.
Q: Why you can`t install driver just for discrete GPU?
A: It is not working because i haven`t got single videodriver (AMD, Microsoft and HP provide only switchable for this platform) and i dont want to lose power save notebook mode which use integrated GPU..
