  1. tl;dr Device Manager stopped displaying video card when I intentionally uninstalled driver and software. Now cannot re-install driver/software because computer/NVIDIA cannot detect card. Lenovo W520, i7-2720 QM @2.20GHz OS: Windows 7, 64bit VC: NVidia Quadro 1000M RAM: 8Gb I have searched the internet high and low for an answer but cannot seem to find one: I *think* I need to force-install video card drivers, but i'm calling on the experts here to help me decide if that's what I need, or something else. BACKSTORY: None of this would have happened if I wasn't such a geek and read all the release notes during Lenovo updates: Chronology of events: download update. read release notes for NVidia video driver that say "if driver version before [some_version_number], uninstall before installing this update" or something like that. (I interpreted this to mean completely uninstall the driver. How I thought it would go down: uninstall, get yellow "!" in device manager, continue with update, tada!...if only.) PROBLEM: This is what happened instead: Uninstalled driver. Then windows tried to fix it for me and re-installed the driver... hmmm, ok, let me uninstall and check the "also delete files" box. damn it's gone from the device manager, i hope it comes back when I install the update....and nope... The Display Device for my NVidia card is completely gone from the device manger. Not hidden, actually gone. Then lots of internet searching over course of a week and here's what I've come up with so far: 1) Turns out, NVidia won't install their driver unless it can detect the card on your system. It must query the Device Manager to determine this, becauase it instantly returns a "The graphics driver cannot find compatible graphics hardware" message. (see attachment.) 2) I was able to find the old driver in C:\DRIVERS\WIN\VIDEO but same problem as (1). 2b) Also ran the bash script I found there which was supposed to set up the drivers, no luck. 3) Everything I can find on the internet regarding driver problems appears to assume a normal device manager: the common answer seems to be "go download latest drivers from NVidia and install", which doesn't work. 4) Found some similar "cant get card to work" forum posts, but non with the same genesis. Any help/tips/leads would be greatly appreciated!
