Delete remnants of its drivers using Driver Sweeper

Update to the latest from device manager OR get them from the manufacturers website OR from a reliable source like filehippo.com (avoid CCC - Catalyst Control Center during installation)

Keep us posted

Thanks. Do let us know what antivirus you're using. You shouldn't be keeping the computer without an antivirus.

Oh sorry, I am not currently with one because the components and OS are new, but I have used Avast on my last computers

Edit: Using Avast

Update this driver: (use the same method using driver sweeper)

Uninstall Avast! it contributes in BSODs. Use free MSE (at least to test)

Recommended antivirus program for Windows 7 based on stability compared to others:-

• Microsoft Security Essentials - Free Antivirus for Windows
• Malwarebytes - The Free version
• Good and Free system security combination.

Run a full scan with both (separately) once downloaded, installed and updated.

They seem to be caused by the atheros stuff again.

Anyway, enable driver verifier. For continuous 36 hours and give us all the dumps you get while its enabled.

• Driver Verifier - Enable and Disable

I tried to use it, following your instructions. I applied to all but microsoft drivers, it was freezing on boot-up. I then tried with only Atheros drivers, and it froze couple times on boot-up and couple times while I actually had a chance to use my computer.
