Windows 7 64bit BSOD 0X4A IRQL_GT_ZERO_AT_SYSTEM_SERVICE RRS feed

  • Question

  • Hi all,

    I'm getting this BSOD alot and cant find the cause of it. Is there anybody who can help me find out the cause of the bluescreen?
    I have all minidump files on my skydrive. Below is what i could find out but from that i cant make out where i have to look to find the problem! I already checked all of my harddrives with Seatools no errors found and i also ran memory test to see if my memory would be failing but nothing there!

  • That is a easy fix...If ram memory is ok,& video/then R.click my computer/properties/Advanced/Virtual Memory/Advanced/Change button...With C: highlited,set to: Let System Manage Click set 2X,close out,restart pc.

    MiniDumps are usually 99% Virtual Memory settings,the above fixes that  64BIT OS are never set to Defaults....

  • The bugchecks were 4A:  IRQL_GT_ZERO_AT_SYSTEM_SERVICE

    To evaluate the BSOD please post logs for troubleshooting.

    Using administrative command prompt copy and paste this whole command.

    Make sure the default language is English so that the logs can be scanned and read.

    Choose the applicable link for the operating system:

    https://www.eightforums.com/threads/language-add-or-remove-in-windows-8.5849/
    https://www.sevenforums.com/tutorials/87317-display-language-change.html

    The command will automatically collect the computer files and place them on the desktop.

    Then use 7zip to organize the files and one drive, drop box, or google drive to place share links into the thread for troubleshooting.

    https://support.office.com/en-us/article/Share-OneDrive-files-and-folders-9fcc2f7d-de0c-4cec-93b0-a82024800c07

    This command will automatically collect these files:  msinfo32, mini dumps, drivers, hosts, install, uninstall, services, startup, event viewer files, etc.

    Open administrative command prompt and copy and paste the whole command:

    copy %SystemRoot%\minidump\*.dmp "%USERPROFILE%\Desktop\"&dxdiag /t %Temp%\dxdiag.txt&copy %Temp%\dxdiag.txt "%USERPROFILE%\Desktop\SFdebugFiles\"&type %SystemRoot%\System32\drivers\etc\hosts >> "%USERPROFILE%\Desktop\hosts.txt"&systeminfo > "%USERPROFILE%\Desktop\systeminfo.txt"&driverquery /v > "%USERPROFILE%\Desktop\drivers.txt" &msinfo32 /nfo "%USERPROFILE%\Desktop\msinfo32.nfo"&wevtutil qe System /f:text > "%USERPROFILE%\Desktop\eventlog.txt"&reg export HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall "%USERPROFILE%\Desktop\uninstall.txt"&reg export "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components" "%USERPROFILE%\Desktop\installed.txt"&net start > "%USERPROFILE%\Desktop\services.txt"&REM wmic startup list full /format:htable >"%USERPROFILE%\Desktop\startup.html"&wmic STARTUP GET Caption, Command, User >"%USERPROFILE%\Desktop\startup.txt"

    There are two files for you to find manually:

    a) C:\Windows\MEMORY.DMP

    Use file explorer > this PC > local C: drive > right upper corner search enter the above to find results.

    b) dxdiag:  

    In the left lower corner search type:  dxdiag > When the DirectX Diagnostic Tool opens click on the next page button so that each tab is opened > click on save all information > save to desktop > post one drive or drop box share link into the thread
