BSOD Error 0x50 After New Windows Update

[lvt08]

So I got a BSOD Error after I just recently installed a Windows Update. I'm not entirely sure if the Windows Update was at fault for the BSOD Error, but I got a Blue Screen the second time I restarted after the Windows Update. The BSOD Error could have been caused by a third party program, but then again I'm not entirely sure.

Here's some more information about the BSOD:

Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7601.2.1.0.768.3
Locale ID: 1033

Additional information about the problem:
BCCode: 50
BCP1: FFFFF901C06558DC
BCP2: 0000000000000000
BCP3: FFFFF960000ECCA3
BCP4: 0000000000000005
OS Version: 6_1_7601
Service Pack: 1_0
Product: 768_1

The Blue Screen also had this message at the top: PAGE_FAULT_IN_NONPAGED_AREA

I had to go back to a previous Restore Point before I was able to access my desktop. Whenever I tried to go into Safe Mode, I would get the same BSOD Error.

Or check your memory with memtest86 for example.

So I just ran the Memory Diagnostic Tool, and it came back with no errors. I even checked in the Event Viewer and the message said, "The Windows Memory Diagnostic tested the computer's memory and detected no errors".

The computer seems to not have the BSOD Error anymore and boots up just fine. But I'm only back at a Restore Point prior to the Windows Update. I'm just afraid if I update my computer again, the BSOD Error will occur. So right now, I'm just scratching my head wondering what caused this BSOD Error in the first place.

Try to prove it's an update. Update in batches of 3 for example. Try to find the culprit.
Which patch is it?

0x50 is almost always a hardware error though.

 

[lvt08]

Will do. I'll be sure to update you on which patch it is once I update Windows. So we'll see how that goes. Thank you. I really do appreciate your help so far.

I've been looking into the 0x50 Error, and it might possibly be a hardware issue with the RAM. I'm not sure if this helps, but I've been using a separate memory stick for the ReadyBoost function. It hasn't given me any issues before, but could that cause a 0x50 Error?

everything is possible. Very easy to test in my opinion.

You should test for hours! And memtest86 is a better test. But first try to prove it's a faulty update.

 

[lvt08]

Haha. All of this testing is very tedious. But I'll try my best! I'll be sure to see if it's a Windows Update that is causing the problem. I have at least 12 updates to go through, but I'll hold off on that tonight since it is getting late. I'll be sure to let you know if it ends up being a Windows Update.


And how would I be able to do a memtest86?

Alright, so here's what I found out since last time. When I was going through the Windows Update, I downloaded and installed the updates in batches of three (like you said). So I went ahead and installed all 12 Windows Update and I restarted my computer a couple times just to make sure if those updates were the cause for the BSOD Error. So surprisely, it turns out that the Windows Update did not cause any kind of BSOD for me. So all is well and I'm happy to report back that I'm not getting the BSOD Error 0x50 anymore!

I'm just still confused on why I even got the 0x50 Error. I still want to figure out what happened so I can either try to avoid running into it again or resolving it, if it happens again. But I think I narrowed it down to a couple things that might have caused the BSOD. 1. It might have been when I downloaded and installed all of my Windows Update at the same time (which now I realize is a bad idea). 2. I disabled Internet Explorer in the Windows Features. I've looked it up and found out that disabling IE might interfere or corrupt Windows. 3. This might not have been a cause, but I'm still not ruling it out... I disabled Hamachi from running as a Start Up on Windows Boot. This could have caused the BSOD, but I'm still uncertain.

So those are just three things that I'm suspicious about that might have caused the 0x50 Error.

I think I might run the memtest86 just to see if it it encounters any problems. Is there a guide on this that you could link me? Once I run the test, I'll be sure to let you know what happens.

It can be anything. Good luck testing

BSOD 0050 after Aug. 12 updates

There were 12 updates, applied all on Aug. 13, computer restarted and ran all day Aug 13.
Aug 14, BSOD and in SAFE MODE. Ran windows 7 recovery DVD to repair non starting system, did not work.
Did a system restore ro the "Critical Update" restore point and computer came up.

Will look at applying in batches of updates.
Computer is in my profile, but, Lenovo I7-3770, 32 GB Memory, Windows 7 PRO, AMD radeon HD 7450 graphics. Disks 1TB primary boot, 512MB secondary.

Hi,

I've the same problem, it's the 12 updates for 12 Aug. I've tried three times, each time I get BSOD when starting up the computer, even starting in safe mood lead to BSOD. Only when I do system restore to before the update then I can start the system normally. I did not install any new software besides the windows updates.

Hi, sadly I can report that i have the same problem, including Blue Screens with 0x50.
A strange thing that is happening after doing a lot of trial and error with different components attached and unattached:

Everything is working okay when my 2nd Harddisk is unattached: this is the harddisk that i mostly use for cache to help my My Main-System SSD

I, too, have this same problem. In my case, I have narrowed it down to two or more of the 9 "Security Updates for Windows 7 for x64" and "Updates for Windows 7 for x64".

Before testing with installing these 9 updates, I restarted my machine several times to ensure I had a good baseline with no BSOD. Now, if I try to install just the 5 Security Updates *or* just the 4 regular Updates, I see the problem. In both cases, however, I only get the Blue Screen x050 stop issue on the 2nd restart. On the first restart, Windows does some "configuring" and it comes up just fine. But if you then restart Windows a second time, it blue screens.

I'm at a loss as to what to try next.

 

[carversmith]

Second boot after update.

I think you might be right about the SECOND boot.
I think I did the update on Tuesday, ran all day, booted on Wed. and it was good
but blew up Thursday.

 

[phainopepla]

Within the batch of 4 updates, I have narrowed the problem to KB 2970228. This update results in the this blue screen issue every time on my machine after the 2nd restart. It is a kernel type update.

And we are not alone:

Blue Screen Stop 0x050 error reported for systems installing KB2976897, KB2982791, and KB2970228 | Microsoft windows - InfoWorld

I am going to follow the article's suggestion and raise this with Microsoft.

 

[lvt08]

Wow. It's good to know that I'm not alone in this. So far everything has been running smoothly. I haven't had the BSOD Error 0x50. I think the cause of the problem might have been when I updated all 12 Windows Update at the same time. So like Kaktussoft said, I only updated in batches of three. I also made restore points after every update just to be safe. I've rebooted everytime for every update and it's been running fine for me.

 

[jacklmx]

Yup, for now, I can pretty confirm it is the kernel updates from Microsoft causing the BSOD. Same syndrome, 2nd restart after update gives BSOD everytime. Without updating, starts fine without any problem.

Saw some posts saying about deleting certain files as a workaround, but I would rather wait for an official hotfix. For now, hide the updates and move along.

I had also started a thread on MS and someone posted a hot fix link from MS as a solution that fixed them up. It didn't help me, however:
