atikmdag.sys BSOD

[apccpa]

I have been getting random atikmdag.sys BSOD on my Win 7 computer, mostly when I boot up my computer. How do I fix this?

Thanks.

This is typically caused by the wrong or corrupt display driver installed. In your case, the ATI Radeon Kernel Mode Driver.

Check to see if there's an update for your video drivers.

Atikmpag.sys

I've installed updated drivers after every BSOD except the one from yesterday.

I've read that sometimes the atikmpag.sys driver must be manually updated sometimes when corrupted?

There are updated drivers on the HP support site for your laptop model dated Aug 7, 2015. There's also a BIOS update. Bring your system up to date then perform the steps in the tutorial below if the BSODs continue.

Update:
I noticed a huge number of ntdll.dll errors in your logs. Before you do the clean start, run SFC /scannow using this tutorial. http://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html
