BSOD playing FSX or FSX SE, SYSTEM_SERVICE_EXCEPTION ,err 0x0000003b

Last several weeks when I play Flight simulator X or FSX Steam Edition after 10-20 minutes of playing I got BSOD in half of flights (not allways but very offen).
For all other it works fine.
I start ASN (Active sky next), vPilot , CAV acras, and FSX.
Last several weeks was update of ASN, vPilot and FSUIPC.
Before that updates BSOD was appear cca. once in six month.
I have make alot of tests (memtest86, disks, heavyload,.. all pass ), drivers are updated, but I can't get it. I suspect on vPilot when it is online (conected to VATSIM)
I have no more idea , and I am very desperate.
Thanks for any answer.

Hello, BornaZg and welcome to the forums. I will try to help you. I looked at the last 5 dump files. Here is what they said.

Code:

fffff880`09180ee8  fffff880`0f2be920Unable 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
 atikmdag+0x3b920

This is the driver you have installed:

Code:

atikmdag
start             end                 module name
fffff880`0f283000 fffff880`10507000   atikmdag T (no symbols)

Please try to update the driver from https://www.sevenforums.com/graphic-c...ndows-7-a.html And please try to do it this way I am going to give you some links that will help you get a good clean install and not have any drivers you don't need that will conflict with other drivers. Download a WHQL driver from https://www.sevenforums.com/graphic-c...ndows-7-a.html . Once you have them downloaded, uninstall you current driver from control panel. next clean up any left over drivers from following this tutorial Drivers - Clean Left over Files after Uninstalling and select only ATI Display Drivers. After you have done that and rebooted, install the new driver, only select custom install and install only what you have to. Very few people need most of what they include. You do not need the audio/HDMI drivers as you already have that in your Motherboard drivers. Unless there is some reason you need them, the only thing you really need is the Display Driver.

Also Please explain why you have a 7900 and a 5450 in the computer.

2 of the dumps listed

Code:

WHEA_UNCORRECTABLE_ERROR (124)
A fatal hardware error has occurred. Parameter 1 identifies the type of error
source that reported the error. Parameter 2 holds the address of the
WHEA_ERROR_RECORD structure that describes the error conditon.
Arguments:
Arg1: 0000000000000000, Machine Check Exception
Arg2: fffffa8008235028, Address of the WHEA_ERROR_RECORD structure.
Arg3: 00000000bf800000, High order 32-bits of the MCi_STATUS value.
Arg4: 0000000000000124, Low order 32-bits of the MCi_STATUS value.

A 0X124 is a generic hardware failure code. It gives no information as to which piece of hardware it is. Or it is possible you have a very bad driver which is causing some piece of hardware to act in unexpected ways. The next dump is the one I am most concerned about, and could explain the 0X124 code above.

Code:

Use !analyze -v to get detailed debugging information.
BugCheck 24, {1904fb, fffff88006e2c088, fffff88006e2b8e0, fffff800043c51c5}
Probably caused by : memory_corruption ( nt!MmCreateSection+395 )
Followup: MachineOwner

In my opinion, from a debugging perspective, a memory error is the worst error you could have. That is because it will cause a BSOD and will get blamed on everything else. So I would like to address that first. Bad memory will make every dump file unreliable. I realize you said you have already run memtest, but I would like you to do it again, but do it this way.

Please Run Memtest86+

   Information

Please download from this site only http://www.memtest.org/ in the middle of the page are the Download links, you can download the ISO.zip or the Auto USB Flash Drive installer.zip

Extract the Zip file. If you chose the ISO image, burn it to a CD using Windows Disk Image Burner or any Image burner you may have. If you downloaded the Auto USB installer, extract it, insert your USB 2.0 Flash Drive and take note of the drive letter. Run the installer, select the Flash Drive Letter, check the format box and press next. It will install memtest86+ to a flash drive. You can use either V4.20 or V5.01. Boot from your selected media. If you use V5.01 it will tell you to press certain buttons at the start, please press no buttons. The test will begin on it's own and continue to run until you stop it. It needs to run for 8 complete passes at the same time or until you receive an error. If you receive an error, stop the test. Even 1 error is a fail. Each pass tests a different part of the ram and each of the 10 tests in each pass tests something different. It takes a minimum of 8 passes all run at the same time to completely test the ram, more passes are better. It is quite a long test and will take several hours depending on how much ram you have. Due to the time length it is best to run overnight. If you have any questions, please do not hesitate to ask

It may work, but it does not seem right, to me. You have 2 cards which are 2 generations apart. one is way more powerful and faster than the other. I would also like you to monitor temps on both cards at all times.

Ok, thanks.

I can't say that will actually work like Steve mentioned you can't mix 2 different types of Generation GPU's together simply no way possible there is a scaling chart for this i am under suspicion that it worked just because but most likely you should be having more bsod's and more often if that is your set up

I also wouldn't have any idea how such a set up would work i googled it and nothing you may be the ver first to crossfire by accident lol

Test the sticks 1 at a time, in each slot. Keep track of which stick and which slot. A bad stick of ram should error out in each slot, which would mean the ram is bad. If a stick passes in all slots except for one, that would show that you have a bad dim slot on your motherboard. What we need to know now is whether the ram is bad or the motherboard is defective.

Did you download the test from Memtest86+ - Advanced Memory Diagnostic Tool? If not, use the test from there to run the tests.
