BSOD wlangzg.sys

I get frequent BSODs, and the screen gets messed up( IE the time quarter of the screen is at the bottom, AND half the left side of the screen is on the right), and it blames it on wlangzg.sys. Please help, I it is driving me mad, not saving my documents often enough.

Welcome to SF!

First, what is blaming wlangzg.sys?

Could you please upload your dmps for analysys? http://www.sevenforums.com/crash-loc...d-problem.html

Now, wlangzg.sys is a network driver. I suggest updating it in Device Manager, or look online on the computer manufacturer's site for an updated driver.

It does seem like a network driver error, but I also wonder if sptd.sys is the cause. Sptd.sys is a driver used by many virtualization programs, such as Daemon Tools and Alcohol 120%. It is notorious for causing BSODs.

I recommend completely uninstalling any such tools you may have, in addition to updating your network drivers.

How can I find what uses that? My family uses this computer, all trying their own thing without actually knowing what it does.

I may have misunderstood you, did you want Revo or Windows? This is of windows

I suspect Virtual Clone Drive is the culprit. Use Revo Uninstaller to remove it completely.
