Video_tdr_failure (atikmpag.sys) is a blue screen error triggered by a faulty, incompatible or corrupt graphic driver. Users face this error after their system has been upgraded or after the drivers have been updated. The good thing is that this BSOD provides you the file name that is triggering the BSOD, which points out where the problem has originated from. Whatever, it is a quick google search will tell where it has originated from. However, this article is related to the atikmpag.sys which is an AMD driver.
This error usually starts if Windows runs an automatic update, or if you have manually updated the graphic’s drivers or if you have just upgraded to windows 8 or 10 from a prior version. In all cases, it is the driver and this is what we will troubleshoot in this guide.
If you are unable to login to Windows due to this error or if the error continuously interrupts while logged in then it’s best to boot to safe mode where a basic graphic driver with minimal load is loaded. You can view steps on booting windows in safe mode (here) and windows 8 (here).
