Congratulations on your new gaming system. As a fellow gamer I just want to say welcome to my world. Now I see you are having some nasty video issues so I am going to try to help you with these problems.
Do you have any other graphical/video drivers installed? I know certain games install like a Nividia driver of sorts.
Couple of other passive tests we can do here to determine if it's that specific driver version.
1) Download a driver version couple of below that. (make sure auto update is off)
2) There should also be a default video driver that normally works.This is in relation to the driver that is installed upon first windows startup before going to ADM website etc. Have you tried just using that to see if it works fine?
Make sure your BIOS is up to date as well.
Have you ran a virus scan of your computer? I would suggest downloading Malwarebytes just to be on the safe side new computer or not.
I would take a look as well herehttp://www.wagnardmobile.com/
You want to use the tool to uninstall and reinstall the AMD driver(s). You will have to boot into safe mode to do this if I remember right (f5/f6)
Run the SFC Command to Repair System Files
You’ll need to do this from and Administrator Command Prompt window. To open one on Windows 10 or 8.1, right-click the Start button and select “Command Prompt (Admin)”. On all versions of Windows, you can also search the Start menu for Command Prompt, right-click it, and select Run as Administrator.
Type the following command into the Command Prompt window and press Enter to run a full system scan:
Run the DISM Command to Fix SFC Problems
On Windows 10, 8.1, and 8, the Deployment Image & Servicing Management tool can fix component store corruption that prevents the SFC command from working properly.
To run this command, open a Command Prompt as administrator. Type the following command and press Enter. DISM will check your Windows component store for corruption and automatically fix any problems it finds.
DISM /Online /Cleanup-Image /RestoreHealth
One last idea as well and it's a long shot.. there are times when audio can affect your graphical items so make sure your audio driver is correct. Is it a USB auido or a onboard audio?
Do these crashes happen just during general browsing? Or is it after the computer wakes up? After you open/close games? Just trying to help pinpoint stuff. If you have multiple monitors you could also keep an eye on what servers /processes are performing extremely higher versus others so we could get that reported when it crashes as that may be indicator as well.
