I recently upgraded from a 1060 to 3060 and I to install I Uninstaller the 1060 display drivers in the device manager because a website told me to. Turned off PC and unplugged PC. Took out old put in new, turned on PC no display. Tried repeating gpu and checking wires it lights up and everything. And tried to take out and use on-board graphics including taking out my cmos for 5 minutes and reset bios but the display won't work for mobo or gpu. I'm stuck and don't know what to do.
