Graphics card AMD Radeon HD 6620G + 7690M

Good day! The problem with the graphics card AMD Radeon HD 6620G + 7690M (HP pavilion dv6-6c09er): one day, while playing in WOT, the picture fell down pixels and hung,rebooted, went into the game, the same thing happened. Decided that outdated driver for the video card, put updated while downloading took off BSOD with error atikmdag.dll and after a reboot would not even turn on and before the OS gave BSOD. Went through the safe and blew the driver. Then completely removed the catalyst drivers and started to install from scratch by downloading from the manufacturer's website, but the install still BSOD.Was W7,decided to install W8, everything is stable, BSOD when installing drivers.Downloaded from site HP driver 8.982.10.5000, too. Now Manager card labeled as Basic display adapter (Microsoft). Integrated 21.06.2006 driver version 6.3.9600.16384 and says that is working fine. From discrete data are the same, just This device is not working properly because Windows cannot load for it needed drivers. (Code 31).Start the driver does not coincide with the video driver, the authenticated POST.
Installed amd chipset drivers and amd software 17.10 software crimson 16.3 and the latest from the site, all to no avail.
What else can be done on this issue? How and what information to gather to solve?
