Searching says that this has something to do with a special wifi antenna. Here's the Dell driver -

The title of your post made me think it was in a diff language. 

Thank you for your post, I did install that driver on Wednesday the 19th but my computer crashed again on Monday morning. I'm wondering if its possible that the wireless card has failed, but I did do the dell espa hardware test and it passed with no issues. So I'm stuck...

Just seeing if you were still having the issue or if you found a way to resolve.

We are seeing this on a good handful of our 7490 Devices and are looking for a solution.

Right Now I am just testing removing the etactista.exe all together by running the ETuninstall.exe from C:\Windows\Ethertronics\.

So if I remember right I ended up finding a driver update for the etactista program or whatever it is. I remember finding it on dells website for the 7490. Id take a look on their website and see if you find any driver updates that are related to the etactista program. After I did that I haven't had any reports of the computer crashing again. Part of the reason im not sure which one it was is because at the time I was trying several different things to fix the issue so im not 100 % certain that fixed it but I think that's ultimately what did it. Google dell drivers and go to the dell site, type in the model and look for the Ethertronics Active Steering Driver.

Good luck
