Random BSODs, MEMORY_MANAGEMENT, ntoskrnl.exe

Hello,

I was hoping someone could help me with a recurring BSOD issue. There doesn't seem to be any pattern as to when they occur; sometimes it will be a month in between instances, othertimes a day or a week. I've followed the instructions here:

https://www.sevenforums.com/crashes-d...tructions.html

and have attached a zip folder with all requested details. Please let me know if there is more information that would be helpful.

-Win7 64bit OEM
-Hardware and OS new in 9/2010

These crashes were caused by memory management, probably by Broker.exe {AmiBroker for Win32 is a process file from company AmiBroker.com}

Please run these two tests to verify your memory and find which driver is causing the problem.

If you are overclocking anything reset to default before running these tests.
In other words STOP!!!


1-Memtest.

*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Memtest86+ - Advanced Memory Diagnostic Tool

*Boot from the CD, and leave it running for at least 5 or 6 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.

Any errors are indicative of a memory problem.

If a known good stick fails in a motherboard slot it is probably the slot.

RAM - Test with Memtest86+



2-Driver verifier

I'd suggest that you first backup your data and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you can restore the system using the Vista/Win7 Startup Repair feature).

In Windows 7 you can make a Startup Repair disk by going to Start....All Programs...Maintenance...Create a System Repair Disc - with Windows Vista you'll have to use your installation disk or the "Repair your computer" option at the top of the Safe Mode menu .

Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).

If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.

Thanks very much for the help JMH. One question on the memtest...I've run already memtest86+ for 49 hours without error, however, I didn't use one stick at a time (I kept all of them in there). Do you think it needs to be re-run with one stick at a time or am I okay?

jonnyb,
No need to re run Memtest...
That is enough.

Just noted you have AVG.

+1 to MSE

Thanks guys for the MSE recommendations. I had removed AVG months ago and had just replaced Avast with MSE minutes before posting here last night. MSE only now.

I followed the Driver Verifier instruction you posted JMH, and got a BSOD as the computer was restarting. I'm using the machine now, so it hasn't happened a second time...but I figured that attaching a new set of dump files was what you would recommend. Please let me know if that's not the case, or if there's anything I should be doing?

Thanks Zigzag.

After using Driver Sweeper, is there a recommended source/method to download the new driver, or do I just let Windows take care of it? I currently have Windows set to automatically update my drivers - will it just reinstall the same faulty driver again?

Pardon the interruption, I've been watching this thread as part of my own desire to learn more about debugging and crash analysis. My question is: Isn't this the Realtec sound driver? Or is it related back to the video driver because it includes HDMI output?

Thanks.

You are absolutely correct and thank you for pointing it out. Thats what happens when you get too little sleep and rely on a database. It always pays to have a second set of eyes.
