Debugging :: BSOD For Windows 8.1 - Page Fault In Nonpaged Area

I recently bought a lenovo 11s with the i5 hashwel and i have been getting a few errors.

Every time I shut down the laptop and close the laptop over, when i try to start it again the BSOD error message "Page fault in nonpaged area (rtwlan.sys)" appears.

I have checked my event viewer and the critical message is a kernal 41 error. - Am not sure if this data is needed but more data rather than less am i right? - the error in event viewer as follows:

- <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">
- <System>
<Provider Name="Microsoft-Windows-Kernel-Power" Guid="{331C3B3A-2005-44C2-AC5E-77220C37D6B4}" />

<EventID>41</EventID>
<Version>3</Version>
<Level>1</Level>
<Task>63</Task>

[Code] ......

I have updated all the drivers i can via lenovos website and using the automatic search on device manager, all of which they say are up to date.

I have checked a possible cause being the bridging between my wlan and wifi but this doesn't exist i don't think.
