BSOD - atikmdag.sys, atimpag.sys, dxgmms1.sys.

Hey folks, my system has started getting the BSOD lately. Only happens when Im playing a game or watching a DVD, and seems to occur randomly, sometimes after 5 mins sometimes after a few hours.

The BSOD always states one of the three files in the post title (atikmdag.sys, atimpag.sys, dxgmms1.sys.) I have tried updating the graphics driver by removing the old driver with driver sweeper and updating to the latest version, and have also checked that my DirectX Is up to date.

My system isnt overclocked and my graphics card is sitting at around 40 DegC according to Catalyst Control Center so I dont think its overheating.

I have attached the files stated in the BSOD posting tutorial (minidumps + Performance Moniter Report) I'm about to run memtest and driver verifier and will post back with the results.

Cheers,

The crash you are experiencing is also known to be caused by ZoneAlarm. Please remove the software, at least to test.

Cheer writhziden, updated my graphics card drivers using the steps above and uninstalled ZoneAlarm. As of yet no blue screens, I reckon it might have been ZoneAlarm as I tried a few different driver versions and was still getting the BSOD, since ZoneAlarm has came off seems to have solved the issue.

Awesome news. Best wishes!
