Well let's go for a hardware approach.

Disable or remove your Yukon network adapter, if possible. If you can't unlug it, go to Device Manager, right-click on it, and select Disable.

Then run this video card test: Video Card - Stress Test with Furmark

Be sure to report the max temp it achieves.

Do you have a friend that would lend you his video card?

Leave the adapter disabled until we get these BSODs figured out.

Is the Yukon Wireless adapter disabled in Device Manager?

I still see drivers loaded in RAM:
