I have been experiencing a BSOD regularly while playing certain games, and anytime I try and torrent. It seems to have started when I first upgraded to Windows 10. My Windows 10 installation is on a SSD. SFC Scan returned with no integrity violations. I ran a full MemTest86 and it completed with no errors found. The Bluescreenview info is as follows:

PAGE_FAULT_IN_NONPAGED_AREA

Bug Check Code: 0x00000050

Caused by Driver: ntoskrnl.exe

Bugcheck code points directly to ram.
1 pass of Memtest isn't enough.

I didnt really have options to do multiple passes when I ran MemTest86.

2 things:

1) memtest86+ is newer than memtest86 (you are probably using memtest86+ , but just making sure)

2) memtest is usually "set it and forget it". After the first test is run it will continue with more passes until you tell it to stop. Are you saying your does not do this? Here is some info about using memtest. It states
When the memtest starts basically let it run and your main goal is to get pass (usually around 10 but more is better for ultimate stability).

It was easier to just test it using a torrent instead. It seems like I stopped the error from happening when I took out a specific memory stick, so I am in the process of returning it, and I am going to torrent as much as I can tonight to try and cause the error to trigger again. It would always BSOD before the 10 minute mark, and I am currently at the 2 hour mark, so thank you for the help!

EDIT: I actually tested out the sticks I know are working in the slots that the last memory sticks were inserted and the issue reappeared. Could this potentially be coming from the memory slots in the motherboard? This issue did first appear when I installed Windows 10, but now that I think of it that was not too far away from when I had originally purchased this motherboard.

Yes. That's why we instruct people to test each memory stick in every slot.

Page faults can also be caused by buggy drivers or apps that have "memory leaks." They don't release memory as they should when closed.

This one might be a 'bad' driver issue, 2 drivers held in RAM appear to be corrupt. Possibly malware or AV involvement, one of those drivers, win32k.sys (Windows graphics) is a common target (Flash exploits, etc.) and, as a result, has probably been the most frequently updated/patched Windows driver in the last 5 years.

The number of older drivers in the dump suggest this is an Upgrade to W10, they're the most likely to have issues with older 3rd party drivers down the line.

It seems like I have verified that it cannot be bad memory sticks or the slot. I had the blue screen in every configuration rotating sticks and slots. Is there anything I can do in terms of finding the cause? This issue seems to have started when I installed Windows 10, and I had about the same stuff installed at the time so I cant narrow the list down very much.

EDIT: I always assumed they were just a scam, but do you think one of those driver update scans would be worth getting? If so what would be the most reputable and preferably free one.

Use the Search facility in the DRT here: https://www.sysnative.com/drivers/

That should give you enough clues for the older drivers listed, if you can't track down a driver for hardware, post the driver name and we'll try to find a recent one. If the driver is for a utility that isn't vital during troubleshooting, uninstall the software package for it, you can always reinstall the latest version once you have regained stability.

Remember, hardware trumps software: if you haven't done 8+ full runs with MemTest86+ on each sick, and in each slot with a known good stick, you'll need to do so if updating all drivers + uninstalling non-vital utilities doesn't fix it.

If you're running Memtest86+ from bootable media (bootable USB stick or bootable DVD), which you should be, windows drivers are a non factor. ;)
You have bad ram.

I have two pairs of memory and unless they BOTH failed or BOTH of the memory slots are causing the issue that cannot be the problem. I spent two hours today taking memory out, and moving it around and it still causes the error in any memory configuration. I tried updating my drivers and now my system is running into a new BSOD at boot 0xc0000021a

What do you mean when you talk about "driver update scans"? I hope you are not using one of those third party driver update scanners like the ones by Slimware that often are found on OEM computers.

Nah I just grabbed what I could from the motherboard page. Guess something didn't go right because it's boot looping now.

A 0xc0000021a bugcheck is entirely different, Usual causes (in order of likelihood): User-mode device driver, system service, or third-party application, Mismatched system files. So, you need to clean out those old drivers.

To give us a better chance of figuring out what's going on, please read and follow the instructions here, attach the required files here in a zip (compressed files) format and we can work through them.

Don't expect a reply from me tonight, it's 01:30 and I'm bushed.

Oh, if you are fresh and eager to dig deeper for us, a dump or two from Driver Verifier would be useful, again, read and follow carefully (even if you do, it might still BSOD on Boot!), ensure you make a fresh System Restore point before enabling it: https://www.sysnative.com/forums/bs...river-verifier-blue-screen-death-related.html

istari,

Tell us about your computer. Give us some details about the hardware: motherboard make and model, RAM make and model. PSU make and model, CPU, CPU cooler make and model, storage make and model (spinner hard drive? SSD?), GPU make and model, etc.

Is this a mass produced computer like from Dell or HP? If so, what is the model number? How long has it been in service?

Your BSOD code points at corruption of system files. Direct result of bad ram.
You can deny all you want, but I speak the truth. Test the ram the proper way.

Well the memory has been failing for a year now if that is the case, but in the process of troubleshooting I now cannot boot. Made an installation media and the automatic repair failed. Sfc scan just results in Windows resource protection not allowing the scan to complete. For some reason the installation media is asking me to boot off the local drive to run system restore as well.

Boot sector is missing or corrupt? Bad memory or failing system disk?
