Solved BSOD after sleep 8.1 update (Page Fault in Nonpaged Area)

Laptop: Lenovo Ideapad Yoga 13 from 2012

I updated to 8.1 two days ago. Since last evening, my computer started having the BSOD (page fault in nonpaged area) after waking up from sleep or opening my laptop lid.

After doing some self research late evening, I updated all known drivers that needed updating. I also updated the latest BIOS. I also did a computer scan and got no errors. Unfortunately, I'm still getting the BSOD.

I used BlueScreenView which highlighted "ntoskrnl.exe + 18524a" as the stack error. I've also attached the dump zip.

Thanks in advance for any help!

All your latest dumpfiles are Probably caused by : rtwlanu.sys ( rtwlanu+dc970 ).
This is the driver for your Realtek Wireless Lan.

Please update to the latest windows 8.1 driver from here Drivers and software - IdeaPad Yoga 13 Notebook.

You have also some other outdated drivers. (Audio, chipset, touchpad, card reader etc.)
Please check/update all your others drivers from the above page to the latest windows 8.1. drivers.

Thanks lifetec. That is bizarre, I've updated every driver on that website (incl the Realtek driver) and also checked on intel's website for all the latest drivers. Did the latest dump files not reflect those changes? I will try again to make sure everything is installed again. Thanks again!

Your outdated drivers based on dumpfile saturday 19 july 12:18

Thanks lifetec! It looks like the Realtek driver WAS the problem. Everything is back to normal now. Thank you!
