BSOD: Memory Management, even after reinstall

[Mark67]

Hello everyone, I am having a very generic BSOD issue with a new computer I built about 2 months ago. I initially built the computer, and everything worked great for about 1 week, then started getting blue screens, constantly, they were complaining about MEMORY_MANAGEMENT, and the ntoskrnl.exe. It go so bad it would blue screen right after reboot with nothing running. I tried removing all the drivers I could think of, but they still happened. They wouldn't happen in Safe Mode, so I still believe it was software and not hardware. Even though, I performed a complete Memtest86+ test, but that returned no errors.

I gave up, and figured I would reinstall W7 Pro, and slowly reinstall the drivers. But after doing that I had no problems. I completed the reinstall, and everything was fine for 2 months no, but the other day I received another BSOD, with the same MEMORY_MANAGEMENT. I figured it was time to ask for help.

Here is the information from the WhoCrashed app:

This might be a case of memory corruption. More often memory corruption happens because of software errors in buggy drivers, not because of faulty RAM modules.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.

I really don't want to redo the system since I haven't been able to nail down the cause. I really hope you guys can help.

In the present situation, the BSOD is caused by avast! Virtualization Driver.

Description here: Driver Reference Table - aswSnx.SYS

Uninstall Avast using Avast Uninstall Utility. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.
Download, install and update those, and then run full system scans with both of them, one by one.

Let us know the results.

That is great news, thanks so much for the help. I have swapped the AV applications and now have MSE. I will give it a few days to see, but I think this will solve my issue.

How is the system running now?

 

[Mark67]

Everything is running smooth as butter!!!!

Closing...

 

[Arc]

Good news
For any further issue, let us know

 

[Mark67]

Ok, so it has been a little more then 1 month, and another BSOD. Looks to be the same type, MEMORY MANAGEMENT.

I have included the current files.

Your crash dumps are not showing any finite probable cause.

Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.

If memtest comes clean, enable Driver Verifier to monitor the drivers.
Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

   Information

Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

   Warning

Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

   Tip

• If you fail to get on the Desktop because of DV, Boot into Advanced Boot Options > Safe mode. Disable DV there. Now boot normally again, and try following the instruction of enabling DV again.
• If you cannot boot in Safe mode too, do a System Restore to a point you made earlier.

Let us know the results, with the subsequent crash dumps, if any. Post it following the Blue Screen of Death (BSOD) Posting Instructions.

I have done both of those tasks in the past, but not for as long as you are asking, with negative results each time. I will do that over the next few nights.

 

[Arc]

If after running memtest over at least 8 passes with no errors, enable driver verifier.

It should be either a failing RAM or any driver passing bad memory information. So we should get some idea out of either of these tests.

 

[Mark67]

So I started the mem test again, I have done it at least 3 times before, and this time (last night) it hit a bunch of errors on the first pass. From there I tried to determine which DIMM is bad, I have 2. And I can't. I tried one DIMM for a few passed, nothing. Tried the next one, nothing. Moved DIMM1 to slot 2 and received 1 error. Tried DIMM2 on slot 2 nothing. Tried DIMM1 back in slot 1 for a bunch of passes, nothing. DIMM2 again in slot 1 nothing. Both DIMMs again together for a few passes nothing.

I am feeling like the RAM is bad, but I am frustrated that I can't get a constant failure rate. I will contact Corsair and see what they will do for me.

 

[Arc]

If Memtest86+ starts showing errors, Stop testing. Errors/red lines means one or more RAM is faulty. But the fault may occur due to a faulty DIMM slot, too, which is a motherboard component. Using memtest86+, you can discriminate between a faulty RAM and a faulty motherboard.

How? Say you have two RAM sticks and two DIMM slots. You obtained errors at the test with all RAM sticks installed. Now, remove all the sticks but one. Test it in all the available slots, one by one. Continue the same procedure for all the available sticks.
How to make the inference that is it a RAM issue or it is a motherboard issue? Suppose you have got the result like that:

test|Slot1|Slot2
RAM1| Error | Error
RAM2|Good|Good

It is a RAM, a bad RAM.

But if you have got a result like that:

test|Slot1|Slot2
RAM1| Error |Good
RAM2| Error |Good

It is a motherboard issue. The particular slot is bad.

Anyway, better you replace the RAM as you have got errors. Let us know how the computer is working with the replacement RAM.

 

[Mark67]

I have tried to determine if it is the RAM or Mobo, but can't. The darn errors don't show up every time I test. Which is weird, from what I have seen in the past is when RAM fails, it fails is a spectacular way.

Oh well. I will have to wait and see what Corsair does for me. I will update as soon as I can.

Thanks for the help again.
