Windows 7: BSOD Error 0x50 After New Windows Update

BSOD Error 0x50 After New Windows Update

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.

Here is the zip file from the DM Log Collector: Attachment 329077

Do Memory Diagnostics Tool
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.

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.

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.
