Mem_mang, Bad_pool_header, pfn_list etc BSODs

Guys please help me, i am recieving several BSODs from the very first day i assembled this PC and installed win7. All my hardware is 4 months old now.

More often i recieve Memory_managment BSOD, in july i started my research on this and got to this forum. So, i collected my dmp files for the month of july and now reporting to you guys. I tried to comprehend these dmp files using WINDBG but i am unable to comprehend them or to pinpoint the problem.

Please help me on this issue......

I am new to this forum please let me know what more information is needed, I have read the method and followed it but still plz correct me if there are still errors.

I beleive this is a hardware error. Might possibly be a bad RAM module.

Have you tried checking the Pc with only 1 of the RAM sticks installed?

This is fairly easy to check. If I were you I would try to rule it out, until someone is able to analze your dump file:

Pull one stick of RAM out, and test with just 1 module and see how it goes. Then, pull it and replace with other one. Test again.

i understand the hardware is only a few months old, but it doesnt rule out the possibility you were sent a bad part. It can and does happen occasionally, unfortunatly.

Also, double check that timings, speed and especially voltage aere set correctly in the bios.

The timings for ram can be manually adjusted to change the way the system uses the ram. in the BIOS, you can set it to Auto to make the RAM run at default settings.

The best test even if the Diagnostics didn't show anything is to run it with each individual sticks and see if any issues are seen. You could have a bad stick and it is only showing errors during normal use.


For tech info:
Timing has to do with clock cycles between accessing the info on RAM. Tight timing is low numbers like 5-5-5-15. (or 4-4-4-18) It is a little complex, but generally, lower numbers = better performance.

A good tool for finding this info is CPU-Z CPUID - System & hardware benchmark, monitoring, reporting


If you are not overclocking your system or have never changed any settings in the BIOS you should be fine.

If I feed exactly the same setting as i find on the corsair website for my model, will it do the job. Also should i check the sticks individually with memtest as well, or windows tool is ok?

I have attached my current CPU-ID Profile. Accordinf to corsair site my model data is:

Alaso attached todays two minidumps, one memory_management ant other PFN_LIST_CORRUPT.

Memtest wouldn't hurt. It might catch something Windows missed. I think the suggested process is to run memtest for a few passes as well.

It is also important to check them individually. If you can run just one stick for a while, use it as normal daily use to see if you get the same issues.

It might also not be the RAM itself. the RAM slots can have issues as well. There is a lot going on between all these system parts. try the one stick at a time in each slot

Ex:

Try Stick 1 in Slot A
Try Stick 1 in Slot B
Try Stick 2 in Slot A
Try Stick 2 in Slot B

Hello ! Welcome to SF !

Most of them a pointing to Memory Management there are lot of crashes with Svchost.exe with SysMain possibly caused by McAfee. I would recommend to uninstall McAfee completely and use Removal Tool How to uninstall or reinstall supported McAfee consumer products using the McAfee Consumer Products Removal tool (MCPR.exe)

I would recommend http://www.microsoft.com/security_essentials/

Uninstall the LogMeIn and you could reinstall it later seems like one of the LogMeIn driver has cause some trouble to the System.
