BSOD Memory_Management Error

[polo53]

Afternoon folks,

Had my PC a while now, however almost daily it has crashed due to a MEMORY_MANAGEMENT BSOD. Unplugging the RAM and re-inserting them fixes it for the day, or unless the PC is shut down for more than ~3 hours.

Finally decided to tackle it head on as I cannot stand the crashing anymore. Ran whocrashed for a readable crash dump and it came up with;

This was probably caused by the following module: ntoskrnl.exe (nt+0x705C0)
Bugcheck code: 0x1A (0x5003, 0xFFFFF70001080000, 0x42E0, 0x42E6000085C8)
Error: MEMORY_MANAGEMENT
file path: C:\Windows\system32\ntoskrnl.exe
product: Microsoft® Windows® Operating System
company: Microsoft Corporation
description: NT Kernel & System
Bug check description: This indicates that a severe memory management error occurred.
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.


Would love some help solving this as the PC is now crashing more often due to similar errors.

Thanks,

Paul

Post it following the Blue Screen of Death (BSOD) Posting Instructions. Stop 0x1A is Memory Management, but it is not necessarily the failing RAM module ... some other things may contribute in it. This data may help to determine it.

Install Service pack 1 and all other windows updates. Otherwise the system will remain vulnerable to threats.

Test your RAM modules for possible errors.

Run memtest for at least 8 passes, preferably overnight.
If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

Also let us know the wattage of the PSU.

Is the computer hot? Report us the heat of the computer after a couple of hours of your normal usage. Upload a screenshot of the summery tab of Speccy. Alternatively, you can publish a Speccy snapshot too: http://www.sevenforums.com/tutorials/311593-speccy-publish-snapshot-your-system-specs.html .

Are you overclockong? As you are getting BSODs, you should stop overclocking and run all the hardware components like CPU, GPU and RAM to their default settings.

Let us know the results.

Power is fine, got an 880W PSU.

PC temperature is fine.

Ran Memtest and one stick of RAM came up with errors in one DIMM slot, but not the other. Could this be the issue?

Added to this I fear my HDD is dying.

 

[polo53]

Ok, so got definite scratching sound coming from my CPU.

When I ran Prime95 on it, and powered it up this noise stopped?

 

[Pauly]

sounds like one of the slots may be bad, test each stick in each slot and you will know for sure

scratching from a cpu? do you mean HDD

 

[polo53]

Pauly,

I ran each stick in each slot for a couple of passes and the only error that came up was in one DIMM slot from one stick of RAM.

I thought it was the HDD, listened closer and it was definitely the CPU. A faint scratching/grinding sound which was confirmed when I have just fired up Prime95 as requested by Arc, running this and stressing the CPU has stopped the noise?

 

[Pauly]

strange !?!?

 

[polo53]

Very, I am very baffled at this moment as you can guess.

It appears my RAM or one of the DIMM slots are faulty and possibly the HDD is on its way out. Added to this the CPU makes a strange noise when idle and it kind of makes me want burn this PC currently!

PC temperature is fine.

Not enough information for them who cannot see it physically. Do what is suggested.

Ran Memtest and one stick of RAM came up with errors in one DIMM slot, but not the other. Could this be the issue?

Now follow the "Part 3: If You Have Errors:" of How to Test and Diagnose RAM Issues with Memtest86+

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.

Added to this I fear my HDD is dying.

Any reason behind believing so other than the sounds?
Do test the HDD using your HDD manufacturer's tool: 7 Free Hard Drive Testing Software Tools

Also, open the computer. Make it sure that the screws holding the HDD with the stand are properly tightened. Also make it sure that the SATA and power are properly connected.
