BSOD - BCCode: 1000007e - atikmdag.sys


Well-Known Member
I've recently had my computer give me a few strange crashes; twice while playing Champions Online but several days apart, it just froze up, gave a graphical glitch, sound stuttering and computer restarted. Then finally, I got an actual blue-screen, giving several error codes and also referencing the file atikmdag.sys. After doing some checking around, I saw a fix that involved reinstalling the drivers, going in and manually expanding atikmdag.sy_ and replacing it. Obviously by the fact that I'm here, this didn't work, and it happened outside the game while just watching a full screen video. This time on restarting I actually got a pop-up listing the codes:

BCCode: 1000007e
BCP3: FFFFF88005BDB368
OS Version: 6_1_7601
Service Pack: 1_0
Product: 256_1

I am currently running Windows 7, 64 bit, Professional.
I have also attached the .dmp file, would anyone be able to look over this and help me find something I might be missing?

Probably caused by : atikmdag.sys ( atikmdag+c7dbb )

as you can see your dump file is blaming the actual GPU driver. Try this, uninstall the GPU driver using this application as it will remove any other old bits of driver lying around from previous driver installs:
Re-install the latest WHQL driver version:

BiosVersion = V2.5
BiosReleaseDate = 07/16/2013
SystemManufacturer = MSI
You have one bios update pending:

avgidsdrivera.sys Fri Apr 18 14:01:26 2014: AVG AV can cause issues with win 7 from time to time. Please remove and install MSE as its more stable:
SASDIFSV64.SYS Fri Jul 22 00:03:00 2011: Superantispyware. Please remove per above and use Malwarebytes:

dtsoftbus01.sys Thu Jun 20 08:22:51 2013: Daemon Tools driver. Possible BSOD issues in Win7 uninstall to test.

Rt64win7.sys Wed Apr 10 04:00:34 2013: Realtek RTL8168D/8111D Family PCI-E Gigabit Ethernet please update:

If after making the above changes you still get a bsod please run Memtest86. You can download the latest version here:
This guide, although old, will show you how to use it:

The more dump files I see the easier it is to decipher your issue so please post any more that you might have and any new dump files that appear.

Thank you for the advice, I'll give it a shot when I get home tonight and let you know. With how infrequent the problems occured I'd like to give it a while before confirming but that sounds very helpful.
