BSOD reboot issue

Hello,

I was wondering if anyone here could help me with my problem. I came downstairs and my computer had BSOD and rebooted. I followed your instructions and the zip file is attached.

I suspect it's my ATI driver as it's the 10.12 prelim and it might not be stable.

Information requested:

Windows 7 Ultimate x64
Installed from TechNet ISO
Hardware age is 1 year
OS was installed on 9/2010

Thank you for any help you can give.

Dumps blame atikmdag.sys, your ATI display drivers

- Boot into safe mode with networking
- Uninstall the ATI drivers including Catalyst Control Center
- Use driver sweeper to remove leftover ATI display driver files Guru3D - Driver Sweeper
- Install the latest drivers ATI Radeon
- Reboot into normal mode
