When I hit for solution it says 'Internet isn't connected right now,check and try again later'.But I'm connected to the internet.Also Blue Screen doesn't mean 'Only Blue screen crash' it can be 'Black' too.And so I've faced black one.screen goes black after opening the lid,it should wake up from sleep mode but instead of sleeping it shutsdown without any prompt.

The source, vwifibus.sys, is a third-party Windows 8 driver file for WLAN devices that is packaged with the Windows 8 iso. According to solvusoft, the file is insecure. It should have been bypassed by your current NIC/WLAN driver, so if you haven't already, update your network drivers. I usually suggest drivers from Realtek, or update drivers from a driver updating program like SlimDrivers or Driver Booster. Hopefully a solid update will ail the issue for good

I fixed it by Additional Windows Updates.Now everything seems to working fine.
