I know this question may be asked often, but I may have a unique situation. I have upgraded my new mobo to a Gigabyte board from an ASUS board. The PC boots and I can login to Windows 8.1, but I get the error of driver conflict. I know that I can clean install windows, I have no problem of that if necessary (download files for a few hours, oh well) but my problem is that I have a pre-installed version of windows, no key, no disc. Can I clean install from that? I also had an idea that I may be able to upgrade to Windows 10 using some kind of clean upgrade. Any help would be useful, thank you.
