Windows 7: BSOD atikmdag.sys

08 Jul 2010   #1

Windows 7 Home Premium 64
BSOD atikmdag.sys

I keep getting BSOD related to that specific sys file every time I've played some game. I believe it's Graphics card related, so I updated the drivers and it didn't help. Watching videos doesn't cause BSODs. I ran the debugging tool, but it didn't reveal any new information to me since I'm no programmer, so all those Hex strings are complete gibberish to me

Well anyway here is the minidump file from yesterday of the latest BSOD

Usual causes: Device driver
In looking through your driver, I can see that you are using Symantec Antivirus program. Third party security program are known for causing BSOD and this is not an exception. Please remove it for testing purpose.

If you need a program to use in the meantime, use Microsoft Essential Security, it's free and haven't known to be BSOD cause:

BugCheck D1, {fffffa7fc721aac0, b, 0, fffff8800579d4fc}

Unable to load image \SystemRoot\system32\DRIVERS\atikmdag.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for atikmdag.sys
*** ERROR: Module load completed but symbols could not be loaded for atikmdag.sys
Probably caused by : atikmdag.sys ( atikmdag+db4fc )

Followup: MachineOwner

.....I still recommend you to reinstall Ati driver. Remember to remove all trace of old driver first before installing new one.
Also, I would suggest you to enable Driver Verifier. Because the stop code D1 is usually device drivers as You can see in the quote above. Driver Verifier will flag bad drivers.

Thanks for the help I've replaced Norton IS 2010 with the MS Security essentials.

I'll try to get BSOD with this setup later and I'll let you know the results.
