Laptop not getting proper shutdown or restart

[nscharan007]

i have lenovo g580 and using windows 8.1
from last few days i'm unable to shutdown or restart my lappy. Whenever i do this its screen goes black but the LED does goes off and after that nothing happens even on pressing power button. Everytime to get out of this i have to remove battery and reinsert it to get the pc on.
So i installed whocrashed.exe and find out the error adn it shows it that the causing problem is ntoskrnl.exe

so i have uploaded my minidump files here..........

Hi nscharan007.

Apparently the issue is network related, and the Broadcom WiFi is failing.

ffffd000`361e0d88  fffff800`0318fe60Unable to load image \SystemRoot\system32\DRIVERS\bcmwl63a.sys, Win32 error 0n2
[COLOR=Red]*** WARNING: Unable to verify timestamp for bcmwl63a.sys
*** ERROR: Module load completed but symbols could not be loaded for bcmwl63a.sys[/COLOR]
 bcmwl63a+0x2c0e60

And this is all about the related info: Broadcom WLAN Driver (Inbox) for Windows 8.1 (32-bit, 64-bit) - Lenovo G480(2184, 20149), G580(2189, 20150), G780

As per it, you have the proper driver installed.

And no other driver is available to download.

In this situation, bettter you contract the windows 8 experts in BSOD Crashes and Debugging - Windows 8 Forums .... they must have an idea about what to do in this stage.
