Hi I think we can all agree that the problem has to be hardware or software. I can't say 100% that you can eliminate software issues with a boot-able Linux CD, But I think that's a great place to start. Here's a great link from one of my favorite resources. Read what HTG has to say about Linux and other rescue options. https://www.howtogeek.com/howto/31804/the-10-cleverest-ways-to-use-linux-to-fix-your-windows-pc/ Here's a quote from the above link. If you don't agree, I would love to hear your thoughts. "There’s a number of ways that you can use Ubuntu to diagnose hardware problems, but the first is really obvious once you think about it—just boot off the Live CD, and start running some applications and test out all the hardware from a working Linux environment. If the system works fine in Linux, the problem is probably a Windows, virus, or driver issue."
