    Random BSOD, Bad_Pool_header 0x00000019, System_Service_Exception 3b


    Hello,

    I have come to the forum after trying to fix the problem myself. I re-installed Windows 7 about a month ago after increasingly common BSOD, thought it was my bad overclock on my custom PC. Just starting crashing again 2 days ago, went through a fresh install with all BIOS settings reset. It's been sorta stable but upon using driver verifier today it crashes while loading windows.

    x64 Windows 7 Pro
    Originally had Vista, system about 3-4 yrs old, but have upgraded a few parts, full information in profile.
    Both OS were for "system builders".

    I broke down and bought a driver updater, so hopefully drivers are up to date. Windows Update current. Not sure if this matters but I am using 2 sets of DDR2 that are have different voltages (1.8V and 2V) and speed settings, CPUZ shows 6144MB running in Dual Channels and DC Mode is Symmetric. Windows 7 MemDiagnostic tool showed no errors, have run check disk and /scan sfc with no errors as well.

    Rolled back Video driver because yesterday Everquest 2 crashed with a D3D error, found at [EQ2] Latest Supported Video Devices and Device Drivers

    Thanks for the help, I'm out of my league and at my wit's end!

    Ok, so I guess it seemed silly to me that I wouldn't update the video driver so I am following the instructions posted here:

    Although my fist BSOD on Bluescreenview has atikmdag.sys (and ntoskrnl.exe) in red, which I'm pretty sure had the newest driver then. I will post results of the OCCT test.

    -Forgot to mention OCCT made me update Direct X 9 when installing it.

    On to Memtest


    Updated ATI driver and ran OCCT GPU test, passed successfully, ran Prime 95 for 41 min for CPU, no errors detected. Now I am testing RAM using Memtest 86.

    Memtest ran for about 11 hours and 7 passes, no errors detected.




    Have a question though, does the fact that my pc crashed during driver verifier prove that it is driver related? Or could it still be hardware?

System freezes, then restarts then blue screens. Performed operating re-installation already, but still does not work. Please advise. Thanks

Now it has happened twice in one night so far so I'm out looking for some assistance. The first instance tonight was while playing...

I've got a Asus G75V running windows 7 that's barely 3 months old but I've been plagued with BSODs since about week 3. About 12 so far. The first half dozen were solved when I changed my modem/router, but now there seems to be a new issue. I've had 5 error code 19's and the seem to be getting...
