Windows 7: Rare BSOD on Windows login, minidump attached.

03 May 2013   #1

Windows 7 Home Premium x64
Rare BSOD on Windows login, minidump attached.


I've run into what seems to be a random BSOD as soon as I successfully log into Windows on a fresh install of Windows 7 x64. It has happened several times now in the last 5 or so days. I've attached the minidump file if someone can take a peek and give me a hint as to what might be causing it, that would be great. :)

Specs are as follows:

Windows 7 x64 (fresh install)
Asus M5A97 Mobo.
AMD FX-8150 @stock speeds
AMD HD 7950 @stock speeds.
2x4gb G.Skill RAM

I have been running this hardware for sometimes with no problems until now.

According to the dump file you provided there are issues with ALSysIO64.sys and atikmdag.sys. The ALSysIO64 driver is the Core Temp - CPU temperature monitor and the atikmdag driver is for the ATI Video driver. These links give update information. Also, in the interest of full disclosure, I edited the dump file to a more manageable size.

Driver Reference Table - ALSysIO64.sys

Thank you very much marsmimar, I had a feeling that it may be due to Core Temp.
