Hi, Would you please let me know if the BSOD occurs frequently or just once? After restarting the computer, does the computer work properly? Before uploading the dump file to SkyDrive, you could do some general troubleshooting steps to narrow down the issue. I suggest you update all devices' driver, chipset from manufacture's site, perform the clean boot. Also, refer to the following article to check if it is helpful. http://windows.microsoft.com/en-us/windows7/Resolving-stop-blue-screen-errors-in-Windows-7 Best Regards, Niki Please remember to click "Mark as Answer" on the post that helps you, and to click "Unmark as Answer" if a marked post does not actually answer your question.
