Greetings once again, and thanks in advance once again for any help. I appreciate it. A couple-three months ago my laptop running Windows 7 Home Premium 64 bit crashed. After Goggling about for a bit I installed Debugging Tools For Windows (x64) so that I could open and read the resultant .dmp file. Of course, opening and reading the file was no problem; understanding what it meant proved much more difficult :blink: . Eventually I came to the conclusion that there was an issue with my Atheros Network driver (athrx.sys), so I uninstalled it, reinstalled it, and made sure it was up to date. This seemed to solve the problem until very recently, as today my laptop crashed for the second time in three days. Now I'm here with the hope that someone with more knowledge than I will take a look at the .dmp file (attached) and point me towards a long-term solution. Thank you.

Download BlueScreenView:
unzip downloaded file and double click on BlueScreenView.exe to run the program.
when scanning is done, go to EDIT - Select All
Go to FILE - SAVE Selected Items, and save the report as BSOD.txt
Open BSOD.txt in Notepad, copy all of the content, and paste it into your next reply

Thanks for the link, Jacee, but my issue is with a laptop running Windows 7, not a server. Plus, I have all things related to Remote Access disabled. I'll look into the functions of wanarp.sys and ntoskrnl.exe and see if I can find anything.
