Windows 7 - Blue Screen, please help

Hello,
I have installed a Windows 7 a few days ago and I had more than 15 blue screens. I found on the internet an article to find what causes the BSOD. I did it as they said, and result was, that my wi-fi card driver is wrong (windows can't handle it. I used the verifer.exe, and after reboot I wasn't able to run Win, so I went to the Safe mode and I 've delete the setting from verifer.exe).. So I uninstalled the drivers, and I thought, that its gonna be ok, but in 1 hour the BSOD found me again. So I decide to install that wi-fi card driver back, so I will be able to use internet. Now, I am really confused, what's causing the BSOD.
The ussual report from BSOD is:

When I tried to open the .xml file to see the report, I didn't find it there (I just copied the address to link bar, and then I went to that folder and nothing have been there (I enabled the hidden folders/files.))


I like Windows 7, but is pointless for me to using it, if I get the BSOD and all work get lost.
Please, let me know, if you need some other details to help me to solve this problem.

Thank you very much

To diagnose the BSOD, use the instructions here: Diagnosing Bsod's (originally posted 02Oct08) - Vox

FWIW - the most useful memory dumps will be the one's that occurred when the Driver Verifier was running.

Copy the results of the analysis to your next post so we can have a look at it.
