Solved Random BSOD involving ntoskrnl.exe (nt+0x70400)

[Caramelo]

I've been having a history of BSOD crashes to restarts of my pc. Upon restart system wants to run chkdsk for F:/ (non system drive). I allowed it to run several times with no errors reported and still get crashes.

I can't really localize it to software or hardware. Who Crashed seems to indicate more possibility of a software error.

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 which cannot be identified at this time.

Diagnostic Test

 RAM TEST

Run MemTest86+ to analyse your RAM. MemTest86+ - Test RAM - Windows 7 Forums

   Note

MemTest86+ needs to be run for at least 8 complete passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero errors here. Even a single error will indicate RAM failure.

Make a photo of the result and post it.

Addition:
If errors show up you can stop the test, remove all sticks but 1 and test this single stick in each slot for 8 passes or until errors show, switch sticks and repeat.
If errors show up and you see them a lot later, no problem, the errors don't affect the test.

Method 2: with a cd
step 3: I don't have Windows Disc Image Burner as an option when I select "open with"
I have CDburner xp and winCD emu mounter as the only 2 choices. Would either of these work?

I don't have any blank usb drives around.

CDburner should be fine. Have used it lot.

 

[axe0]

As long as the USB is bootable and has some free space left you can install it, a USB doesn't have to be wiped for the test

 

[Caramelo]

Thanks guys. I used CD burner and started the memory test. 10 hours later and it's only through 5 passes. The good news is that there are no errors yet. I'll report back when it does all 8.

Edit: is 2 hours per pass normal?

 

[Caramelo]

8 Passes, no errors.

 Malware scan

Please run a threat scan with Malwarebytes*, a full scan with your AV, scan your system with Adwcleaner, Kaspersky TTDSKiller, ESET Online Scanner and SuperAntiSpyware

   Note

*(Uncheck trial version in the installation process)

Please upload the scan logs.

 

[Caramelo]

Could not figure out how to capture the AVG logs but no threats were shown.

I deleted all the tracking cookies shown.

The reported trojans and pups were false positives.

 

[axe0]

The reported trojans, worms and PUP's are by definition no false positive.

 

[Caramelo]

Superspyware offers the opportunity to correct their assessment of the true nature of what they id as trojans and pups. Those id'd by the various scans are associated with game patches from reputable game publishers and from official download sites and have been in place for many years before having the current crash difficulties.

 

[axe0]

Maybe, but Super AntiSpyware only reported 2 trojans, 2 PUP's and a bunch of cookies.
The other scans reported more trojans, worms and PUP's.

I don't know where you got your mods, but there still are reasons why certain mods are marked besides of false positives. It isn't something important too, but I just want to ask you to watch what your download and remove programs and files you don't need or use. PUPs, malware and related stuff will make troubleshooting more difficult, even if it is a mod for games.

 

[Caramelo]

I appreciate your point.
I'm beginning to think that my Win 7 has been installed so long (8 years) and has gathered so many corruptions that I should probably do a clean install (as much as I dread that) and perhaps if I go that route, step up to Win 10. Your thoughts?

 

[axe0]

First see how it goes with a clean install, after that you can make the decision of going to Windows 10.

 

[Caramelo]

I think the hardest thing will be to back up all my data and files that I don't wish to lose. I have no idea how to back up the drivers.

 

[axe0]

Drivers need to be reinstalled.

 

[Caramelo]

Yes, but do I need to back them up or does the Win 7 have most drivers and does it install them as part of a clean install?

 

[Layback Bear]

Windows 7 along with your motherboard DVD/CD will have most of the drivers you will need.
I would suggest updating your video card from the manufactures web site.
Then check Device Manager and see if any other drives need attention.
I recommend installing all your programs fresh on the same partition Windows is installed on.

To back up your data to a external drive I recommend Macrium Reflect.

Here is a little tutorial by Brink I always read before doing a Clean Install.

I will go back to watching and let you and axe0 alone.
