I just installed windows to my new 830 128gb SSD. I had windows update install 91 updates, installed avast(which wanted to reboot), installed nvidia drivers(which also wanted reboot), and audio card drivers(which wanted reboot). Now when I finally try to do my first restart. My PC goes to shut down then says stage 1 of 3. Then it went to the normal "Shutting down..." screen and never showed stage 2 or 3. The progress circle is still moving but it has been over 30min and the pc has not finished w/e it is doing. Did I screw something up with all the different updates at once?
Possibly, Windows updates should only be installed by themselves, it might be writing video drivers to your system, which you've attempted to write/overwrite with the drivers (same for audio). I always install Windows, run all updates, then go back and install any drivers Windows didn't have native support for or ones that provide better functionality than the Windows drivers.
