Windows 8 Blue Screens ntoskrnl.exe & EhStorClass.sys Page fault in nonpaged area

akimoggie · Jul 17, 2014

Hello!

My girlfriend and I are having some problems with her new Toshiba laptop. At random times it bluescreens, usually giving a PAGE_FAULT_IN_NONPAGED_AREA (0x00000050) error. A lot of what I've been reading about it state that it could be an issue with the ram sticks, however the tests we've done (SFC, windows memory diagnostic w/ multiple passes) came up clean--we haven't tried memtest86 yet because we haven't had time, but plan to do that next.

Her laptop is as follows:

Toshiba Qosmio X70-ABT3G22
OS: Windows 8.1
CPU: Intel Core i7 4700MQ
RAM: 24GB (2x4GB + 2x8GB) Samsung DDR3-1600mhz

More info about the ram sticks in question:

(slot 3 is the same as slot 2 and slot 4 is the same as slot 1)

We used Blue Screen Viewer to look at the last two BSODs she had.

That's all the info I have at the moment, let me know what other info is needed. Any and all advice is really appreciated! Thanks!

edit#1: Also, overheating doesn't seem to be an issue--the BSODs occur regardless of whether she's playing a game, browsing the internet, or doing nothing. She's watched her CPU usage, memory usage, and computer temperature and everything is totally normal. Also, she's been on point in regards to updating drivers and Windows updates and such, but I'm thinking something slipped through the cracks. It's a new laptop and all.

Is this the way the laptop was configured for RAM? Or have you added some?

If you've added new RAM, try removing it and seeing if the problem remains.

Also as you mentioned the best way to check RAM is with Memtest, leave it run overnight. In my experience, it can take some time before errors start appearing. So let it run 6 - 8 hours. If after that long it hasn't produced any errors, they your RAM is fine.

techgeek :

Thanks for your response!

The RAM was pre-configured that way, direct from Toshiba. We haven't fiddled with any of the hardware.

Until we have time to run Memtest, are there any other things we should check into? Or are all indications pointing towards something physically wrong with the ram (as I fear)?

techgeek · Jul 17, 2014

Looking at the dump file really makes me think bad RAM. However you could also try opening a command prompt window and typing:

chkdsk c: /r

It will tell you that it can't lock the drive and ask if you want to schedule the check disk for on the next reboot, answer Y and close the command prompt and reboot.

This will do a full scan (include and surface scan) of your hard drive. It will take a long time depending on how big the hard drive is.

P.S. I really think it's RAM though, the crashes were with different drivers, but at the same address in both dumps.

techgeek :

Alright. If it comes back clean after the memtest we'll try that. I think you're right, though--there's been several more BSODs since this morning and all of them have the same address. I'll post them here for reference, but at this point the BSODs have become frequent enough that I don't see how it can be anything other than the RAM.

Here's the last crash logs.

(Really running the gamut of ominous error messages there!)

Anyway, Memtest will be running so I'll get back to you after we come back from work and all. Thanks again for your help.
