I believe the errors related to the Yukon Ethernet Controller and the video card have been resolved for a while now. I stopped receiving those errors after enabling IPv6 in Zone Alarm and uninstalling and reinstalling the video card driver respectively.
The recent problems that prompted this post are the 124 errors. A gentleman over at Microsoft Answers suggested that one of the recent dump files implicated my processor as needing to be replaced. I was looking for some additional opinions though before taking hardware out of my system or attempting a re-install of Windows.
I know 124 errors are not easy to pinpoint (since it could be the physical hardware, a driver, the OS, or other software).
As I mentioned earlier, I have already performed Steps 1-6 in the article mentioned. Should I go forward with a clean install of Windows?
Any other analysis or ideas anyone?
