BSOD Happenes a lot, especially when trying to launch a game.

The last dump file in the logs was at 11:27, is that the correct time?

If so, the Realtek device is still the problem and the drivers are dated the same as before.

Code:

0: kd> lmvm RTL8192cu
start             end                 module name
fffff880`02ce0000 fffff880`02df2000   RTL8192cu T (no symbols)

If that is the correct log we need to find a more updated driver for that device.

I'm a bit confused here, it's a Realtek Wireless Network adapter driver that's causing the problem but your USB adapter is an Encore, I didn't pick up on that at first. I'm just checking your motherboard manual as I think the Realtek wireless adapter must be on board.

Can you open Device Manger, expand the Network Adapters and take a grab with the Snipping Tool. How to Use the Snipping Tool in Vista Then upload the shot in your next post. Screenshots and Files - Upload and Post in Seven Forums

Just to double check, is your motherboard just a P8Z77 or does it have a suffix?

Could you set a System Restore point then uninstall the Realtek Family Controller via Device Manager. Reboot and see if Windows installs a driver for it.

Hopefully, if the device has uninstalled it should have taken the driver with it. Test the machine out for a few days and if you get any more BSODs then post them up straight away. If you are confident the issue is sorted you can mark the thread as Solved, you can always mark it Unsolved if the problem returns.
