you have the 82583V correct? I'm assuming so. The only microsoft driver I have loaded is e1i63x64.sys if you're getting a cpudrv64.sys error, i'm not sure where that is coming from. On another post I saw someone say that the cpudrv64.sys is from the INTEL system requirements lab that looks for hardware. Perhaps when you tried to install the intel drivers and it couldn't find an adapter that somehow caused all of this.
I've done a clean install and haven't tried installing the intel drivers on windows 8.1 because I KNOW they won't install. I'm just confused as to why you're getting BSOD and others including myself aren't. hmm..
