Hey guys, Being the most active Windows community I know, I figured I'd ask here in hopes for a quick response. Anyone know the cause as to why drivers won't install or update? Windows Update fails, manual install fails (USB sound card, tap driver, graphics), and automated installers fail. Not sure why the hell this is happening, but I noticed it after I had an issue with my Nvidia driver causing TDR BSODs. After uninstalling, I can't reinstall the same/older/newer driver version for the card... Nor even TAP for activation. It was a clean install, too. 8.1 RTM with the Oct. rollup and mouse fix implemented into the ISO via KUC. Scouring the internet, I can't find anything to help and this is getting quite annoying.
