Windows 7: BSOD pagefault in nonpaged area 0x00000050 ntoskrnl.exe+75bc0

Your SSD is a Samsung EVO, is the firmware up to date and did you apply the fix, Performance restoration? You will have to scroll down, but data migration is there, Samsung Magician, Firmware and the restoration fix. Samsung SSD Downloads | Samsung SSD

After that the only thing I can come up with this early for me is,

SeaTools for DOS and Windows - How to Use thr long snd short tests on the mechanical drives

Then Be sure to create the system restore point Manually, the link is below. In some cases, that is the only way back. Sort all drivers by provider and select all non Microsoft drivers. Then use the computer as normal and if there is anything that causes a BSOD, do that often. Use the computer any way you want. It will seem pretty sluggish and a little slow. That is Normal. What we are doing is putting extra stress on the Non Microsoft drivers in an effort to make the troublesome driver BSOD and be able to catch it. Please use it for a minimum of 24 hours of actual use or until you have had a couple of BSODs. Then re run the BSOD posting instructions and upload the files.

What is Driver Verifier:
It puts stress on the drivers, and tries to make the faulty driver crash the computer. It is designed this way, to attempt to trap the offending driver.


What you will notice:
It will tend to make the computer rather slow and sluggish because the drivers are being stressed.
warning   Warning

Before enabling DV, make sure you have created a system restore point before enabling Driver Verifier. make a System Restore Point manually before enabling DV.

Let us know the results, with the subsequent crash dumps, if any.

OK, I had read that Panda was pretty trouble free, but I'm fine switching back to MSE. Is it just a matter of removing via the uninstall programs menu, or will that not remove everything?

You can either leave it for now if you want until we find out the real problem. If you want to, I think you have the Panda Cloud AV, if that is correct, you can uninstall it from the add/remove programs then use their uninstaller CloudAV Standalone Uninstaller - MediaCenter Panda Security

OK, I'll just leave it for now. I'm not really tied to any particular AV--just heard good things about Panda. If at some point you feel I should switch back to MSE, I will do so.

I'm working on your other suggestions now. So far, the Samsung EVO SSD already had latest firmware
and I had previously completed the performance restoration process, but just completed again to be sure. Magician shows drive status as good.

Downloaded the SeaTools iso and will run that on the mechanical drive in a few minutes, as well set up the system restore point before enabling driver verifier.

OK, when you finish that please download and install Malwarebytes Free version Malwarebytes | Free Anti-Malware & Internet Security Software During installation watch out for add ons and just uncheck them so they will not install and uncheck the trial real time option and ude it as an on demand scanner, Update it and run a full scan with that and Panda.

Also download and install Superantispyware Free edition, same rules for that and anything else downloaded from the internet, update that and run a full scan. Delete everything found

Scan with Kaspersky TDSSKiller:
Anti-rootkit utility TDSSKiller
Anti-rootkit utility TDSSKiller

And, in my opinion the best one
ESET online scanner:
Free Virus Scan | Online Virus Scanner from ESET
Free Online Virus Scanner | ESET

Run a full scan with them also. I know it sounds like a lot, but it isn't really. It will make you as sure as possible there are no viruses causing this. Keep me updated on your progress.

Will do. Seatools for DOS did not work for my internal HDD--said it could not be found--I wonder if it only tests the primary drive (C:/) and in my case that drive is the SSD. I am using Seatools for Windows and completed short passes on internal HDD and the two external drives. Long pass completed for internal and one external. All passed no problems. Still waiting for it to complete on larger external drive. Once done, I will proceed with everything else.

Hi, I followed all directions completely. Here are the results:

--SSD already had latest firmware, and I completed the restoration fix again (previously completed it a couple of months ago).

--all HDD's passed Seatools for Windows short and long generic tests. My 2TB external drive took a really long time to complete the long test--seemed to be disproportionate to the size of the other drives (i.e., probably 4 times longer than my 750GB external drive).

--Driver Verifier enabled and restarted windows after. No BSOD as of yet.

--installed and ran full scans from Malwarebytes, Panda, Superantispyware, Kaspersky TDSSKiller, and ESET online scanner. Only things found aside from a handful of tracking cookies was this from Superantispyware:

Malware.Trace
(x86) HKU\S-1-5-21-655957656-552148623-2211127539-1003\SOFTWARE\MICROSOFT\WINDOWS NT\CURRENTVERSION\WINLOGON#SHELL

and this from ESET:

C:\Program Files (x86)\Panda Security\Panda Security Protection\Tools\PandaSecurityTb.exe a variant of Win32/Toolbar.Visicom.A potentially unwanted application deleted - quarantined
C:\Users\Tim\AppData\Local\Temp\{0BEF29BA-E8E9-42B9-B179-DAFB28E7B9C4}.exe a variant of Win32/Toolbar.Visicom.A potentially unwanted application deleted - quarantined

After my last post, I restarted and windows did not start back up correctly. I tried again and it loaded, but with the "windows has recovered from an unexpected shutdown" window. I assume it was the verifier-related sluggishness, but it sure took a long time to get the minidump, etc. info using the diagnostics tool. Anyway, it is attached for review.
